Top 5 IoT Trends

IoT devices can help companies use their data in many ways, including generating, sharing and collecting data throughout their infrastructure. While some companies are leaping into IoT technology, others are more cautious, observing from the sidelines to learn from the experiences of those pioneering IoT.

When looking through these five key trends, keep in mind how IoT devices affect and interact with company infrastructure to solve problems.

1. IoT Cybersecurity Concerns Grow

As new IoT solutions develop quickly, are users being protected from cyber threats and their connected devices? Gabriel Aguiar Noury, robotics product manager at Canonical, which publishes the Ubuntu operating system, believes that as more people gain access to IoT devices and the attack surface grows, IoT companies themselves will need to take responsibility for cybersecurity efforts upfront.

“The IoT market is in a defining stage,” Noury said. “People have adopted more and more IoT devices and connected them to the internet.” At the same time they’re downloading mobile apps to control them while providing passwords and sensitive data without a clear understanding of where they will be stored and how they will be protected—and, in many cases, without even reading the terms and conditions.

“And even more importantly, they’re using devices without checking if they are getting security updates…,” Noury said. “People are not thinking enough about security risks, so it is up to the IoT companies themselves to take control of the situation.”

Ben Goodman, SVP of global business and corporate development at ForgeRock, an access management and identity cloud provider, thinks it’s important that we start thinking of IoT devices as citizens and hold them accountable for the same security and authorization requirements as humans.

“The evolution of IoT security is an increasingly important area to watch,” Goodman said. “Security can no longer be an afterthought prioritized somewhere after connectivity and analytics in the Internet of Things. Organizations need to start treating the ‘things’ in the Internet of Things as first-class citizens.”

Goodman said such a measure would mean that non-human entities are required to register and authenticate and have access granted and revoked, just like humans, helping to ensure oversight and control.

“Doing this for a thing is a unique challenge, because it can’t enter a username or password, answer timely questions, or think for itself,” he said. “However, it represents an incredible opportunity to build a secure network of non-human entities working together securely.”

2. IoT Advancements In Healthcare

The healthcare industry has benefited directly from IoT advancements. Whether it’s support for at-home patient care, medical transportation, or pharmaceutical access, IoT solutions are assisting healthcare professionals with more direct care in situations where they cannot provide affordable or safe hands-on care.

Leon Godwin, principal cloud evangelist for EMEA at Sungard AS, a digital transformation and recovery company, explained that IoT not only makes healthcare more affordable—it also makes care and treatment more accessible and patient-oriented.

“IoT in healthcare will become more prevalent as healthcare providers look to reduce costs and drive better customer experience and engagement,” Godwin said. “This might include advanced sensors that can use light to measure blood pressure, which could be incorporated in watches, smartphones, or standalone devices or apps that can measure caloric intake from smartphone cameras.”

Godwin said that AI is also being used to analyze patient data, genetic information, and blood samples to create new drugs, and after the first experiment using drones to deliver organ transplants across cities happened successfully, rollout is expected more widely.

Jahangir Mohammed, founder and CEO of Twin Health, a digital twin company, thinks that one of the most significant breakthroughs for healthcare and IoT is the ability to constantly monitor health metrics outside of appointments and traditional medical tests.

“Recent innovations in IoT technology are enabling revolutionary advancements in healthcare,” Mohammed said. “Until now, individual health data has been mostly captured at points in time, such as during occasional physician visits or blood labs. As an industry, we lacked the ability to track continuous health data at the individual level at scale.

“Advancements in IoT are shifting this paradigm. Innovations in sensors now make it possible for valuable health information to be continuously collected from individuals.

Mohammed said advancements in AI and Machine Learning, such as digital twin technology and recurrent neural networks, make it possible to conduct real-time analysis and see cause-and-effect relationships within incredibly complex systems.

Neal Shah, CEO of CareYaya, an elder care tech startup, cited a more specific use case for IoT as it relates to supporting elders living at home—a group that suffered from isolation and lack of support during the pandemic.

“I see a lot of trends emerging in IoT innovation for the elderly to live longer at home and avoid institutionalization into a nursing home or assisted living facility,” Shah said. Through research partnerships with university biomedical engineering programs, CareYaya is field testing IoT sensors and devices that help with everything from fall prevention to medication reminders, biometric monitoring of heart rate and blood pressure—even mental health and depression early warning systems through observing trends in wake-up times.

Shah said such IoT innovations will improve safety and monitoring and make it possible for more of the vulnerable elderly population to remain in their own homes instead of moving into assisted living.

3. 5G Enables More IoT Opportunities

5G connectivity will make more widespread IoT access possible. Currently, cellular companies and other enterprises are working to make 5G technology available in more areas to support further IoT development.

Bjorn Andersson, senior director of global IoT marketing at Hitachi Vantara, a top-performing IoT and  IT service management company, explained why the next wave of wider 5G access will make all the difference for new IoT use cases and efficiencies.

“With commercial 5G networks already live worldwide, the next wave of 5G expansion will allow organizations to digitize with more mobility, flexibility, reliability, and security,” Andersson said. “Manufacturing plants today must often hardwire all their machines, as Wi-Fi lacks the necessary reliability, bandwidth, or security.”

But 5G delivers the best of two worlds, he said—the flexibility of wireless with the reliability, performance, and security of wired networks. 5G provides enough bandwidth and low latency to have a more flexible impact than a wired network, enabling a whole new set of use cases.

Andersson said 5G will increase the feasibility of distributing massive numbers of small devices that in the aggregate provide enormous value with each bit of data.

“This capacity to rapidly support new apps is happening so early in the deployment cycle that new technologies and infrastructure deployment can happen almost immediately, rather than after decades of soaking it in,” he said. “With its widespread applicability, it will be feasible to deliver 5G even to rural areas and remote facilities far more quickly than with previous Gs.”

4. Demand For Specialized IoT Data Management

With its real-time collection of thousands of data points, the IoT solutions strategy focuses heavily on managing metadata about products and services. But the overwhelming amount of data involved means not all IoT developers and users have begun to fully optimize the data they can now access.

Sam Dillard, senior product manager of IoT and edge at InfluxData, a data platform provider for IoT and in-depth analytics use cases, believes that as connected IoT devices expand globally, tech companies will need to find smarter ways to store, manage and analyze the data produced by the Internet of Things.

“All IoT devices generate time-stamped (or time series) data,” Dillard said. “The explosion of this type of data, fueled by the need for more analytics, has accelerated the demand for specialized IoT platforms.”

By 2025, around 60 billion connected devices are projected to be deployed worldwide—the vast majority of which will be connected to IoT platforms, he said. Organizations will have to figure out ways to store the data and make it all sync together seamlessly as IoT deployments continue to scale at a rapid pace.

5. Bundled IoT For The Enterprise Buyer

While the average enterprise buyer might be interested in investing in IoT technology, the initial learning curve can be challenging as IoT developers work to perfect new use cases for users.

Andrew De La Torre, group VP of technology for Oracle Communications at cloud and data management company Oracle, believes that the next big wave of IoT adoption will be in bundled IoT or off-the-shelf IoT solutions that offer user-friendly operational functions and embedded analytics.

Results of a survey of 800 respondents revealed an evolution of priorities in IoT adoption across industries, De La Torre said—most notably, that enterprises are investing in off-the-shelf IoT solutions with a strong desire for connectivity and analytics capabilities built-in.

Because of specific capabilities, commercial off-the-shelf products can extend IoT into other industries thanks to its availability in public marketplaces. When off-the-shelf IoT aligns with industrial needs, it can replace certain components and systems used for general-use practices.

While off-the-shelf IoT is helpful to many companies, there are still risks as it develops—security risks include solution integration, remote accessibility and widespread deployments and usage. Companies using off-the-shelf products should improve security by ensuring that systems are properly integrated, running security assessments, and implementing policies and procedures for acquisitions.

The Future Of IoT

Customer demand changes constantly. IoT services need to develop at the same pace.

Here’s what experts expect the future of Iot development to look like:

Sustainability and IoT

Companies must embrace IoT and its insights so they can pivot to more sustainable practices, using resources responsibly and organizing processes to reduce waste.

There are multiple ways a company can contribute to sustainability in IoT:

• Smart energy management: Using granular IoT sensor data to allow equipment control can eliminate office HVAC system waste and benefit companies financially and with better sustainability practices.
• Extent use style: Using predictive maintenance with IoT can extend the lifespan of a company’s model of manufacturing. IoT will track what needs to be adjusted instead of creating a new model.
• Reusing company assets: Improved IoT information will help a company determine whether it needs a new product by looking at the condition of the assets and use history.

IoT and AI

The combination of Artificial Intelligence (AI) and IoT can cause industries, businesses and economies to function in different ways than either IoT or AI function on their own. The combination of AI and IoT creates machines that have smart behaviors and supports strong decision-making processes.

While IoT deals with devices interacting through the internet, AI works with Machine Learning (ML) to help devices learn from their data.

AI IoT succeeds in the following implementations:

• Managing, analyzing, and obtaining helpful insights from customer data

Top 5 Cloud Networking Trends

1. Enterprise Network Strategy In The User’s Home

Changing workforce expectations have led many companies to a more globally distributed remote workforce – a trend that also rises with the cloud. 

As a result, enterprise networking infrastructure now has to support users in their homes.

Drit Suljoti, co-founder and CTO of Catchpoint, a digital experience monitoring platform provider, explained that consumer-grade networking technology does not always offer the levels of support and visibility necessary for remote work, which is increasingly becoming a problem.

“Organizations across the board have experienced the frustrations and performance volatility that can result from consumer-grade WiFi, VPN clients, and increased dependence on the internet from the employee’s wider household,” Suljoti said. “At the ground level, how can IT support desks ensure they have the necessary visibility into the daily digital life of their remote employees? 

“These mission-critical teams need the ability to understand the digital performance of an individual’s device, network, and applications, and the third-party providers they rely on. This is even more essential when employees are working remotely, without on-site support to troubleshoot performance issues.”

Bob Friday, VP and CTO of Mist, Juniper’s artificial intelligence (AI)-driven enterprise business, believes that many companies are starting to respond to this remote work shift by increasing networking security and monitoring their employees’ remote work environments.

“[A] major shift is in how enterprise-level networking trends are becoming increasingly important for personal users as well,” Friday said. “Whether you’re an executive at a company or you work in a profession that puts you into contact with sensitive information, the continued normalization of remote and hybrid work environments means that enterprise-grade networking and security will move into the home networking space.

“To ensure end-to-end network visibility, reliability, and security, we can expect enterprise-grade networking solutions to begin permeating remote and hybrid workforces, as enterprise IT teams take an even sharper look at their network edge.”

2. Networking With Remote AI Support

Users and enterprise devices often need technical support that was normally provided in the office. As remote work – again, supported by the cloud – continues to become a standard approach, many companies are adopting AI solutions to assist with customer experience (CX) and support requirements of the network.

“More help is needed in managing this critical infrastructure, which is why AI has become a necessity for network management,” said Friday. “Enterprises and technology providers have already adopted AI assistants in their networking support teams. Cloud AI has enabled a new tech support model, one that has created the volume and quality of data necessary to train AI technologies. 

“This AIOps model has led to incredible progress. At present, AI can answer up to 70% of support tickets with the same effectiveness as a domain expert. Eventually, this AIOps technology will move all the way to the end-user. 

“And like the average human employee, AI has the ability to learn and improve over time, thus providing a better customer experience consistently and proactively. But unlike the average human employee, that skill and expertise is not lost when they retire or quit. The more that AI is used as part of the IT help desk, the more the technology can improve its answers and, ultimately, the end-user experience.”

3. The Growth Of Intent-Based Networking (IBN)

Networking technology continues to grow more sophisticated. Particularly with the more widespread use of software-defined networking (SDN), intent-based networking is being used more in enterprise networks that want additional business intelligence (BI), configuration management, and other features embedded in their networks. All of these feature are part of the growing sophistication of cloud technology. 

Eric McGee, senior network engineer at TRG Datacenters, a data center vendor, explained why IBN is helpful to network administrators who want to better understand and manage their networks.

“One important networking technology trend that network engineers need to take note of is the emergence of intent-based networking,” McGee said. “The main role of IBN is to capture business intent and apply these insights across the network, ensuring that network administration is aligned with business intent. In other words, the IBN framework will receive an intent from the business and translate it, or encode it into the configuration of the network, resulting in the desired changes. Now, the network infrastructure is aligned with the business’s current needs.

“IBN also enables the automation of network administrative tasks involved, such as the configuration of networks, mitigation of risks, as well as the reporting and solving of network issues. Implementing IBN as a form of network administration makes the process of creating, managing, implementing, and monitoring network policies easier, simpler, and less labor-intensive. A lot of the manual effort put into traditional configuration management is made redundant when IBN is implemented.”

4. Holistic Networking Offerings

Traditional networking solutions typically need a variety of hardware and software components to work properly. 

However, as networks continue to evolve their software-defined, cloud, edge, and solutions, many networking vendors are offering more holistic networking packages to manage every aspect of the network.

Patrick MeLampy, Juniper Fellow at Juniper Networks, a top global networking company, believes that enterprise client-to-cloud connectivity is one of the biggest drivers behind more unified networking packages.

“I’d have to say that there are a few key networking trends that are gaining steam,” MeLampy said. “Enterprise client-to-cloud connectivity service offerings will take off. This means we’ll see Wi-Fi, wired, routing, and security capabilities pulled together, all in one simple offering, making it more efficient and effective for teams to manage ever-expanding networks.”

5. Managing Network Data With Different Ops Methodologies

With more software- and cloud-based networking solutions used across the board, several companies are looking into new ways to manage and read their networking data.

Richard Larkin, manager of North America sales engineering at NetBrain, a next-gen network operations company, believes that the knowledge and approach of different ops teams are particularly applicable to new ways of automating network data management. 

“The days of managing networks with SNMP polling and traps as well as Syslog data are almost over,” Larkin said. “Many enterprises still leverage these telemetry sources, but it’s not enough. We need a more comprehensive solution harvesting data, from API, CLI, packet, netflow, and other sources, to get the complete picture as well as visibility into SD-WAN, SDN, cloud, and SaaS offerings.

“A trend that I am seeing is the blending and blurring of lines between NetOps, SecOps, and DevOps. With networks becoming more software-defined and cloud-based, organizations are trying to fill the gap of the traditional network monitoring data (SNMP, Syslog, etc.) with homegrown solutions using Python, Ansible, and other coding. What would be interesting is if there was an easier way to codify the knowledge of the NetOps teams that required minimal coding and can be produced in minutes, not hours, days, and weeks.”

The Future Of Cloud Networking

With the vitality in cloud networking for businesses, these trends above will further develop in the future, offering more opportunities for the growing market. From automation and network efficiency, businesses will see more benefits than ever.

Looking ahead, the future developments in cloud networking may include:

• Networking automation: Using network automation will help a company with a variety of tasks, including configuring, provisioning, managing, and testing network devices.
• Network-as-a-Service (NaaS): NaaS is a cloud model that allows users to control their network and attain the performance they expect from it without having to own, build, or maintain their infrastructure.
• 5G Cellular: 5G, the latest cellular update, allows a new network designed to connect virtually, including machines, devices, and more.
• Wi-Fi 6: Wi-Fi 6 is the new release for Wi-Fi network protocol that can be faster than its predecessors due to more focus on traffic and other technologies.
• Network Efficiency: With improved network scalability in the next couple of years, traffic will be aggregated for IP and Ethernet platforms. 
• Universal Networks: In the future, networking will have the ability to add new protocols and functions for better service. This can include services such as Ethernet services, mobile services, and more.

Along with the listed predictions and processes, more technologies are developing in networking, including AI, ML, the cloud, edge computing, Internet of Things (IoT), and more as they continue to play an increasingly important role in the future of networking. 

Bottom Line: Top Cloud Networking Trends

With remote training becoming a necessity in businesses, networking can help manage workers at home with a network strategy and remote AI support – a trend that leverages cloud networking to a great extent. 

Companies can use tools such as software-defined networking (SDN), intent-based networking, business intelligence (BI), and configuration management through their networking infrastructure.

Interview: Networking Market

How did you first start working in the networking market? 

I started my career as a computer scientist out of MIT, in the voice communication market. I helped pioneer the creation of Unified Communications (phone calls, voice messages, and emails, at the start). This was just as business communication was transitioning from memos and phone calls to voice messages and email. I transitioned to networking just as WAN optimization technologies enabled voice and video to be effectively sent over networks.

What is your favorite thing about working at Riverbed Technology?

It’s working for a company that, at its heart, is about using technology to make complex problems easy. Riverbed didn’t invent WAN optimization, but they dominated the market with a product that was literally install-and-forget-about-it. The product just worked.

What sets Riverbed Technology’s networking approach or solutions apart from the competition?

For our Network Performance Management products, the portfolio that I lead, Riverbed’s edge has always given the greatest depth of insight to expert users. We have the broadest and deepest telemetry for all aspects of network performance on the market. Our latest focus is to leverage that data with Artificial Intelligence so that even non-experts can quickly find and fix performance issues.

The Networking Market

What is one key new networking technology that particularly interests you? 

Not purely for networking, but I think Artificial Intelligence and Machine Learning are going to enable issues to be resolved almost before people notice an issue. In the world of networks, I look forward to streaming telemetry (hopefully) replacing SNMP polling as a way to gather device status.

What is one new networking technique that teams should implement? 

Combining what we think of as separate disciplines, network performance management (NPM), and application performance management (APM), into coordinated teams. Both sides are working with applications running in computing elements that communicate over networks. I believe treating these as separate disciplines makes progress harder on both sides.

What is one new networking strategy that companies should implement? 

User experience first. We have all sorts of ways to measure how well networks are operating. But, at the end of the day, what truly matters is the performance that the person on the PC, laptop, or mobile phone is experiencing. What better than to measure that directly – as the key metric of performance?

What is the biggest networking mistake you see enterprises making?

Having too many separate tool silos. Sure, every group knows the data they consider most relevant. But what happens when each tool indicates “there’s no problem”? Much better to have a consistent set of collected data – so that you can be sure that issues can’t “slip through the cracks.”

What are some current trends in the networking market that are promising? 

The biggest trend that I see is a “left shift” of skills and tasks. There just aren’t enough networking experts; the people that have those skills have way too many demands on their time.

That’s where AI/ML comes in: it allows some of the approaches that the experts use to be automated and simplified, so more junior people can solve some problems that only experts could fix before.

What are the biggest factors that are driving change in networking?

The biggest factor is clearly the sheer amount of data we all work with. I joke with my kids that I remember when storage capacities were measured in megabytes. Now, 100Gbps links are common; organizations are (or will be) seeing data volumes measured in Petabytes, Zetabytes, and Exabytes. Networks operating at peak performance all the time is not just a convenience; it’s essential.

How has networking changed during your time in the market?

I’ve seen the pendulum swing a few times: all IT happening from data centers; the growth of the PC; client-server architectures; applications moving from the data center to the cloud (and sometimes back again). We’re now in a world where both people and the machines running applications could be anywhere. All of which makes the network that much more important.

Where do you predict the networking market will be 5 or 10 years from now?

Each new advance in network transport (faster wired and wireless technologies) has enabled more computing power for more people. I see that process continuing. Beyond higher-definition movies on huge screens, I’d like to see reliable, high-speed networking around the globe (and in orbit). There should not be “haves” and “have nots” when it comes to networks.

Personnel in Networking 

What is one new networking development your team wants professionals to know?

That your future is all about leverage: not just the problems you fix on your own…but helping build the tools that will enable teams to take on the more mundane of the problems you solve.

If you could give one piece of advice to a networking professional at the beginning of their career, what would it be? 

To realize and appreciate that many people may not know what you do…but that the networking profession provides the essential capabilities that keep the world running.

With the shortage of tech talent, how is your team finding and retaining professionals to work in networking?

We’re not actually seeing a challenge in finding talent. The challenge is in figuring out the best ways for teams to work together, across geographies and time zones, to achieve collaborative goals.

For the greatest business impact, what should networking professionals be focusing on most in their roles? 

The same as in any business situation: know who your customers are. For networking professionals, many of these “customers” may work for your own organization. Your success will come from enabling these people to be as productive as they can be.

What is one of your favorite parts of the work week? How does it encourage or inspire you? 

My manager’s staff meetings. I have such a brilliant and creative set of colleagues. Though the biggest inspiration really comes from seeing people find the humor in whatever challenge has just arisen.

Do you have a favorite way to recharge during the workday? 

My family has a three-year-old Labrador retriever. She needs a couple of heavy exercise sessions in the park each day. Some of my most creative ideas have come while I’m throwing a frisbee or tennis ball for her to fetch.

What are your favorite hobbies or ways to spend time outside of work?

I’ve just become the Executive Officer for my sons’ U.S. Naval Sea Cadet unit; the only unit in the country that’s a dedicated musical group. My lifetime highlight was marching with the band down Constitution Avenue in Washington, DC, as part of this past year’s July 4th parade.

Continue reading to learn more about the features, pros and cons, and functionality of a circuit-level gateway.

For more information, also see: Why Firewalls are Important for Network Security

How Circuit-Level Gateways Work

Circuit-level gateway firewalls work by providing a layer of security between TCP and UDP throughout the connection by acting as the handshaking agent. They authenticate the handshake by scanning and examining the IP addresses of the packets as the 5th layers, and stand between the incoming web traffic and the sending hosts.

This type of firewall is rarely used individually as a stand-alone solution for network security. They’re best combined with a stateful inspection firewall for securing layers 3 and 4, and an application-level firewall to secure Layer 7.

Circuit-level gateway firewalls are able to maintain a network’s security by constantly validating and authenticating the connection by only allowing safe data packets to pass. In the case of malicious activity detected in an incoming data packer, the firewall terminates the connection and closes the circuit connection between the nodes.

For more information, also see: What is Firewall as a Service?

Features of Circuit-Level Gateways

When implementing a circuit-level gateway firewall, whether individually or in tandem with other network security and firewall solutions, there is a set of features you can expect upon deployment.

Some of circuit-level gateway firewalls’ most notable features include:

TCP Handshake Verification

While circuit-level gateways don’t check incoming data packets for the destination IP address, they check and verify the TCP handshake required for establishing the connection, and whether it adheres to the security and privacy standards set by the network’s admins.

It checks and authenticates the connection through the three-way TCP handshake. The firewall synchronizes both sides in the connection sessions and mitigates unauthorized interception.

Hides the Network’s Information

When communicating with outside hosts, servers, and devices, a circuit-level gateway’s firewall doesn’t reveal the private information of your network to avoid the exploitation of communication information.

After the initial verification of the communicating party, this type of firewall doesn’t intervene with the type and volume of traffic exchanged.

For more information, also see: Artificial Intelligence in Cybersecurity

Stand-Alone Security Functionality

When it comes to securing the communication and movement of data packets in the 5th layer of the OSI model, circuit-level gateways are fully capable of being a stand-alone solution. It can be used to centralize the management and security policy of the entire layer without the need to integrate third-party tools.

SOCKS Protocol Configurations

When used in a network firewall setting, SOCKS servers allow the hosts of the network’s servers to fully access the public internet while providing complete protection from unauthorized actions and web traffic interception attempts.

Depending on the ports and protocols used in the network communication, the gateways can either use SOCKS as the proxy of the connection or as the client.

For more information, also see: Data Security Trends

Advantages of Circuit-Level Gateways

Similarly to the wide variety of other types of firewall solutions, circuit-level gateway firewalls come with a set of benefits and drawbacks.

Following are a handful of the most notable circuit-level gateways firewall advantages:

• Keeps private your network’s identifiable information
• Simple and quick to implement
• Doesn’t exhaust time and computational power by avoiding the monitoring and scanning of individual data packets
• Lightweight software with a low impact on the network’s performance
• Cost-efficient in both software and hardware expenses
• Doesn’t require dedicated proxy servers for each applications
• Highly flexible for address schemes development

“A circuit-level gateways firewall operates at the OSI model’s session layer, monitoring TCP (Transmission Control Protocol) connections and sessions,” writes Anshuman Singh, senior executive content developer for Naukri Learning.

“Their foremost objective is to guarantee the safety of the established connections. Circuit-level gateways are inexpensive, simple, and have little impact on network performance,” adds Singh.

Disadvantages of Circuit-Level Gateways

Following are a few of the most notable drawbacks and disadvantages of circuit-level gateways firewalls:

• Unable to detect malicious files in data packets
• No support for advanced content filtering
• Cannot monitor the communications of applications
• Only compatible with TCP connections
• Unable to protect more than Layer 5 of the OSI model
• Requires initial configuration of the network protocol stack

When to Use a Circuit-Level Gateways Firewall

Picking out the primary or sole tools for securing your network can be tricky, especially with the wide variety of firewall types and generations available commercially. Luckily, the use cases for a circuit-level gateway firewall aren’t numerous.

For one, it’s the perfect option if you’re on a low budget and unable to provide the necessary hardware and bandwidth to account for the weight of more complex firewall solutions. They allow for more control over the connections of your network with minimal effort as it doesn’t need the capabilities or configuration otherwise required for in-depth packet filtering and monitoring.

On their own, circuit-level gateways aren’t considered to be the most effective at securing a network, especially one where devices and users communicate frequently with outside servers. However, compared to more simplistic options, such as a stand-alone deep-packet inspection firewall, circuit-level gateways are an improvement.

Examples of Circuit-Level Gateways Firewall Providers

Forcepoint

Forcepoint is an Austin, Texas-based software company that designs, develops, and sells network security and management software. It offers solutions ranging from data protection and cloud access security to advanced NG firewalls, and even cross-domain solutions.

Stonesoft is one of Forcepoint’s Next-Generation Firewall (NGFW) solutions. It provides both stateless and stateful packet filtering alongside circuit-level firewall capabilities with advanced TCP proxy control agents.

It’s an intelligent firewall solution that can be extended all the way to Layer 7, implementing built-in SSL VPN and IPsec capabilities.

Forcepoint’s NGFW has accumulated high user ratings over the years on various third-party review sites. For example, it has a 3.8 out of 5 rating on PeerSpot and 4.4 out of 5 on G2.

In 2020, Forcepoint was recognized for 4 years in a row by Gartner as a Visionary in Network Firewalls.

Juniper Networks

An enterprise leader, Juniper Networks is a Sunnyvale, California-based developer of computer networking products. It provides its clients with all the necessary software and hardware to build, maintain, and manage a network, from routers and switches to network security and management software.

The Juniper Networks SSR120 is a network appliance that’s software-driven with various NGFW capabilities. It’s a branch of Juniper’s SSR (Session Smart Router) portfolio and supports network security and management capabilities from Layer 2 all through to Layer 5.

Similarly, it includes various additional features such as traffic encryption, built-in VPN support, advanced traffic filtering, and DoS/DDoS protection. 

Juniper’s solution is trusted by its users, as demonstrated by the positive reviews on various third-party reviews sites, such as PeerSpot with a 4 out of 5 rating, and Gartner with a 5 out of 5 rating.

Bottom Line: Circuit-Level Gateways

Unlike packet inspection firewalls, circuit-level gateways don’t filter and monitor the contents of exchanged data packets with outside sources. Instead, they confirm the security and authenticity of the connection, and verify that it doesn’t pose a threat to the network through its IP and address and other superficial parameters.

It’s not fully safe to use as circuit level gateway as a stand-alone solution for protecting a network with a wide variety of components, but it remains one of the most affordable and non-resource-intensive network security solutions. There are multiple firewall solutions that include, or consist of, circuit-level gateway capabilities. They are offered by household names in the computing networking cybersecurity and management software industry, such as Juniper Networks and Forcepoint.

The local machine, the thin client, is simply used to display the results in a way that is as close as possible to what you might see when running the program locally. These local machines are also called a slim or a lean client.

How Do Thin Clients Work?

Thin clients work on an operating system locally and carry flash memory. All applications and data for thin clients are stored in the central server and allows local printing, device support, web browsing, and processing network computing.

The thin client devices used to access remote user data can be strong and operate within a budget for companies that use a thin client. As connection protocols grow and improve, businesses can gain much more effectiveness out of thin clients and virtual desktops.

Client management console is a benefit for thin client users. It is a virtual tool that is installed and remotely manages all deployed employees. A client management console can create, clone, and show the company’s customized image to the deployed thin client devices. 

Different thin clients, therefore, support different workloads. For instance, the VNC protocol described above doesn’t (yet) natively support video streams. You could open a video player on a VNC-connected desktop, but you’d see at most one frame every second or so, even on a broadband connection.

On the other hand, you could run a web browser that supports Flash, connect to a remote video server, and enjoy full-screen H.264 video playback — on the exact same network connection. It’s also possible to open a VNC connection in a web browser, since a VNC server can provide a Java-based browser applet that runs at just about the same speed as the binary client and supports most of the same features.

For more on management: The Network Management Market 

Thin Client Use Cases

In theory, most any application can be run on a thin client. In practice, getting the most out of a given app in a thin client setting may require functionality that isn’t available through the client device.

Thin clients lend themselves most naturally to certain kinds of usage:

Thin Client In High-Security Or Public Environments

Any place where security is an issue typically benefits from some type of thin-client setup. Data is kept on the backend; the client only presents the user with whatever they are authorized to see, and tampering with the client generally only results in a broken client instead of stolen data.

Thin clients are also useful in public environments — libraries, government offices, airlines, Internet cafés — where many people may use the same machine, and there’s a need to reduce the amount of risk due to leftover data from previous sessions. The risk is not eliminated — it’s always possible to “shoulder-surf” someone else’s work — but it is reduced by dint of there being minimal data on the terminal itself.

Thin Clients For Minimal Workloads

Thin clients are well-suited to workloads where the actual work being done is not CPU-intensive, and requires only as much client feedback as would be provided by a web browser. In fact, many such thin clients may well be web browsers, since they provide toolsets to cover most of the user interaction you might need in such a scenario.

Thin Clients For Apps With Higher Computational Demand Than The Client Hardware

One common scenario for repurposing older PC hardware is to convert it into a thin-client system of some kind. Applications that would not run well on the PC itself could be published from a server to that PC across a thin-client connection, provided the app’s functionality wouldn’t be hindered that way.

For cybersecurity news: Cisco Report Shows Cybersecurity Resilience as Top of Mind

Types Of Thin Clients

Thin clients can be grouped into two basic categories: software thin clients and hardware thin clients.

A hardware thin client is a device that has been created specifically to run thin-client software and little else. It’s easy to compare it with the “dumb terminal” or “diskless workstation” of old, albeit with better graphics, but there are some other differences.

Thin Client Examples

For one, the exact makeup of a hardware thin client varies. It could be an existing PC that’s been stripped down to do nothing more than run the client software, or a custom-designed piece of hardware that again does little more than connect to the remote host and perform the needed client display functions. One example of such a device is the nComputing system, a hardware thin-client mated with a server which allows dozens of users to be supported by a single desktop-class machine.

A software thin client is, simply, an application running on whatever host is available, whether dedicated (as with a hardware client) or just commodity hardware. It may use some of the abilities of the local host — hardware-based graphics acceleration, for instance — to better render the remote client’s interface.

But the exact choice of host doesn’t have to be a system designed solely as a connecting client—it can be a full-blown PC with its own workload, running the thin-client application in conjunction with other things.

Provided is hardware thin clients and software thin client software examples:

Examples Of Hardware Thin Clients

• Wyse Thin Clients: Wyse, owned by Dell, was once a maker of terminals, but has since branched out into thin clients. Aside from connecting to remote hosts using ICA, RDP and VMware View protocols, Wyse has their own proprietary extensions to accelerate and enhance multimedia (including Flash) and multiple-display support across the wire. The clients are powered by a variety of operating systems depending on which model you use: Linux, Windows XPe, Windows CE, Citrix XenDesktop and their own proprietary ThinOS.
• Leadtek Virtual Desktop System: Leadtek normally known for making graphics cards, but they also manufacture the Virtual Desktop System line of thin-client devices, which use the Teradici PCoIP protocol. The VP 200H is an add-on card which converts an existing system into a PCoIP client, while the VP 200P is a standalone device with low power consumption.
• Oracle/Sun’s Sun Ray: A line of hardware clients designed to connect over local and wide-area networks, with a variety of configurations (e.g., both single and dual display connectors). The remote host can be Windows, Linux or Solaris OS, as Oracle ships support for all three operating systems.

Examples Of Software Thin Clients

• X Window System (X11): This is the graphical windowing system developed for current breeds of UNIX, as discussed above. X11 works on a very low level, however — the core of the protocol doesn’t address things like windows, buttons, menus, style/theme controls, etc. — so those things are typically handled by other components. The emphasis with X11 has been on backwards compatibility and “provid[ing] mechanism rather than [user interface] policy,” so it’s still regarded mainly as a low-level transport protocol. X11 clients and servers exist for multiple systems apart from UNIX, which allows UNIX X11 apps to be published to, for instance, the Macintosh or Microsoft Windows.
• For more information on Windows 11: Microsoft Windows 11’s Use of AI
• Terminal Server Service (Termsrv.exe): Microsoft’s proprietary protocol for remote desktops and applications isn’t just used for thin client connections, although that’s one of its major functions. It can also be used to publish a specific windowed application to another system — for instance, from a virtual machine to a physical one, as XP Mode in Windows 7 does for making XP applications available to the system at large.
• Citrix ICA: The Citrix family of remote-application products works similar to Terminal Services, but supports both clients and application servers across multiple platforms. Citrix also works closely with the Xen hypervisor, so that virtual machines running under Xen (or individual applications running under those machines) can be published across the network.
• Sun Ray/Appliance Link Protocol: Oracle’s (formerly Sun Microsystems) proprietary thin-client protocol, which allows their Sun Ray thin-client hardware to connect to Sun servers. A proprietary software client made by Oracle also exists, which allows any client that can run the software to connect to a Sun Ray / ALP server. (An open-source software implementation of the client hardware, called SoftRay, is also currently being developed in Java.)
• PCoIP:  Short for “PC-over-IP”, this is Teradici’s proprietary protocol for remotely connecting to a virtualized machine. It can be used with dedicated thin clients (“Zero Clients” in Teradici’s parlance); a PC with an add-on card, such as Leadtek’s “Virtual Desktop System” lineup of devices; or in software, such as in VMware’s View 4 application.
• Virtual Network Computing (VNC): Short for Virtual Network Computing, this allows one computer to virtualize its desktop for another computer, regardless of the OS on either end. It allows for very precise rendering of the remote desktop, but at the cost of bandwidth and latency during major screen updates. Many extensions have been built into VNC to allow accelerated performance on specific platforms (e.g., Microsoft Windows), and a number of commercial (RealVNC) and free (TigerVNC) implementations exist.
• Web Browsers: The most common real world version of a software thin client might well be a web browser, especially given the amount of rich interactivity provided by most web sites. Google’s Chrome OS is one current example of a browser-based thin client, where the client contains just enough code to run the browser and any minor maintenance required on top of that (networking, local cache, etc).

Limitations Of Thin Clients

The single biggest disadvantage to a thin client is its dependency on the network. Since everything a thin client does is provided across a network connection, the network becomes both a single point of failure and the single biggest performance bottleneck in the system. If the network slows down, experiences latency or cuts out completely, the client may do anything from lag to stop working entirely.

The exact construction of the thin client and server model in question can ameliorate some of the problems with a slow or flaky network. A web browser, for instance, can locally cache everything it downloads, although the size of the cache will vary depending on the capacity of the client hardware. Most anyone who’s browsed from their cache during a DNS outage will be familiar with how useful this can be. 

However, thin client dependency on the network remains. Also, networks are still many orders of magnitude slower than the slowest internal component in even a modest PC— the cost of which may be comparable to a hardware thin client. This may limit a thin client’s cost-effectiveness compared to a more conventional local-workstation solution.

Bottom Line: Thin Clients

A thin client is a computer system used to run applications where most processing is done on a remote server linked over a network, grouped into two basic categories: software thin clients and hardware thin clients.

All applications and data for thin clients are stored in the central server and allows local printing, device support, web browsing, and processing network computing. Thin Clients are great for high-security and public environments, minimal workload, and higher computational demand for apps.

The benefits of FWaaS include cloud speed, flexible cloud scaling, global reach, flexibility, security and performance improvements, and more. It also will benefit a company during cybersecurity threats that might arise.

See below to learn all about why companies are using FWaaS as a network security solution.

Why Use A FWaaS Solution?

• What are the benefits of FWaaS?
• Why are firewalls critical?
• Why is the as-a-service model important?
• Bottom line

What Are The Benefits Of FWaaS?

Beyond the core aaS benefits, FWaaS enjoys specific improvements, including cloud speed, flexible scaling, and network architecture support. Here are the primary benefits of FWaaS:

Cloud Speed

Local firewall appliances can be constrained by local appliance limitations such as memory and processor capabilities. FWaaS deploys as many resources as needed and thus delivers the faster performance needed to match the performance cloud applications.

Flexible Cloud Scaling

FWaaS cloud architecture grows and shrinks as needed to provide right-sized architecture for all needs.

Local hardware deploys with fixed maximum capacities:

• Often must be purchased much larger than needed to accommodate future growth and thus wastes money
• Can be overwhelmed by traffic or packet inspection requirements at peak use, even if the appliance size meets the average needs
• Can become a bottleneck for traffic, especially with bandwidth-constrained connections to the internet. Technically, this is an issue with local architecture, not the firewall appliance itself, but this is an inherent issue with locally deployed resources

FWaaS vendors deploy:

• Unlimited computing power to examine packets and filter malicious data
• Unlimited scalability to meet future needs whether they increase or decrease
• Direct connections between remote users and cloud resources to eliminate local network network bandwidth constraints
• The cloud scale and data of all customers to provide robust training for AI and ML algorithms to deploy better security for all customers.

Global Reach And Control

Local appliances only control local networks, whereas remote offices have their own local appliances that may be inconsistently deployed and difficult to manage remotely.

FWaaS enables a concentrated group of firewall experts to configure, deploy, monitor, and maintain consistent security policies for all offices and remote workers in a centralized manner. In addition, FWaaS can be deployed consistently within cloud resources closer to global offices to minimize delays in network packet transmission

Increased Flexibility

Appliance-based firewall upgrades and network restructuring require considerable labor and time to design and implement:

• Physical appliance replacement or reconfiguration
• New software installations (and possible downtime)
• New firewall rules that need to be implemented on each physical appliance one at a time

By comparison, FWaaS installs upgrades instantly, new features are added with the click of a mouse, and new security rules deploy in a few seconds.

Modern Network Architecture Support

Local firewalls use decade-old architecture technology to protect legacy local networks well. FWaaS expands coverage to modern IT architecture:

• Cloud-first FWaaS provides better coverage for cloud-based solutions (SaaS, PaaS, IaaS, etc.) by enabling secure direct connections between users and resources without local network choke points.
• FWaaS integrates naturally with software-defined wide area networks (SD-WAN) to provide integrated security as well as scalable architecture.
• FWaaS provides a fundamental component for secure access service edge (SASE) solutions and often will be packaged as a feature with a SASE product.
• FWaaS can provide consistent coverage and rules for geographically dispersed remote users, resources, and networks.
• FWaaS protects multiple cloud deployments and SaaS solutions with consistent deployment so long as the FWaaS vendor supports that cloud.
• FWaaS easily supports and protects bring-your-own-device (BYOD) devices with standardized policies and protection.

Security And Performance Improvements

Local firewalls can lead to security and performance weaknesses:

• Local hardware can be overwhelmed with deep packet inspection requirements and slow down network traffic.
• Some firewalls cannot inspect Secure Sockets Layer (SSL) encrypted traffic, while others simply slow down traffic because they perform poorly.
• Local firewalls can expose the network to attack because of delays to implement patches or the latest security intelligence updates.
• Some remote users or resources may bypass firewall appliances to access cloud resources directly to avoid performance issues and expose themselves to security risks.

FWaaS uses cloud-native scale to deploy resources as needed to:

• Perform consistent packet inspection without performance delays even for SSL traffic.
• Keep network security capabilities fully updated with immediate integration of security intelligence and vulnerability patching.
• Security can force all traffic to flow through FWaaS solutions without user or operational complaints about performance bottlenecks.

Simplified Network Architecture

Local IT staff deploy local firewall solutions for a new office. However, this often results in an IT architecture of many different brands and models that can complicate deployment, training, management, and consistency.

FWaaS simplifies network architecture by allowing resources to connect to a standardized solution with consistent security controls and configurations.

Why Are Firewalls Critical?

Firewalls typically provide the first line of defense for a resource. IT managers historically deployed firewalls to protect networks, but firewalls evolved significantly to expand protection in several ways.

In terms of capabilities, firewalls began to incorporate other technologies to provide unified threat management (UTM) or improved threat detection from deeper packet inspection in next-generation firewalls (NGFW).

In terms of deployment, we now use firewalls embedded in operating systems to monitor traffic for specific applications and containers and as web application firewalls (WAF). Of course, to truly understand the importance, we also must understand the threats addressed by firewalls and FWaaS.

Threats Defended By Firewalls And FWaaS

In general, firewalls block malicious traffic and viruses before they can reach the network, application, server, or website.

FWaaS specifically defends a dispersed IT network that can contain a variety of geographically dispersed local networks, remote users, data centers, and cloud resources such as software-as-a-service (SaaS) applications, platform-as-a-service (PaaS) resources, or infrastructure-as-a-service (IaaS) infrastructure.

Specifically, FWaaS and firewalls typically:

• Block malicious web traffic such as bad bot activity, malware, packets that indicate intrusion activity, IP address spoofing, and traffic from identified malicious websites
• Perform network inspection and monitoring to detect, alert, and block malicious traffic between network resources, including cloud resources

More advanced firewalls and most FWaaS also deploy advanced features that enable additional capabilities:

• Internet Protocol security (IPsec)-enabled firewalls defend against data corruption, denial-of-service (DoS) or distributed denial-of-service attacks (DDoS), data theft, man-in-the-middle (MitM) attacks, network attacks from untrusted computers, unauthorized attempts to control network-connected devices, untrusted communication, and user-credential theft.
• Advanced firewall products can also block Domain Name System (DNS) attacks or spoofing, outgoing sensitive data, zero-day attacks with assistance from artificial intelligence (AI) or machine learning (ML) algorithms.
• Secure Sockets Layer virtual private network (SSL VPN)-enabled devices block unauthorized remote connections to the network and protect remote users against attacks or information sniffing.

Why The As-A-Service Model Is Important?

All as-a-service offerings share common benefits stemming from their business model. Most organizations enjoy:

Concentrated Expertise

As-a-service vendors’ experts do the heavy lifting on the back end to create superior technology with a user-friendly interface. Customers need less expertise internally to configure and deploy the technology.

For FWaaS specifically, organizations can use a dramatically smaller number of firewall experts internally to configure and deploy firewalls for the entire organization. In addition, the infrastructure of the firewalls themselves will be deployed, configured, and maintained by firewall experts with experience and technical capabilities beyond the economic reach of most organizations.

Ease Of Support

Simplified processes make aaS solutions fast and easy to purchase, deploy, maintain, and support. Some aaS solutions allow for many, if not all, of these tedious and time-consuming IT tasks to be eliminated entirely. For FWaaS, the advantages manifest as:

Purchasing

FWaaS do not require six-figure appliances and financing that needs approval from the finance department. Many FWaaS solutions can be purchased in minutes with a credit card and an email address.

Deployment

Deployment becomes simplified and requires less resources and expertise. Whereas physical appliances need to be shipped and delivered, and virtual appliances need to be downloaded and installed, FWaaS is instantly available. Moreover, physical and virtual appliances deployed locally or in the cloud all require internal experts to deploy correctly, secure, and connect with the rest of the IT infrastructure.

FWaaS guides users through their options and mainly requires IP addresses to be entered correctly. Even a single internal firewall expert can establish a set of baseline configurations that can be consistently deployed across a wide variety of resources. Customers that need additional help or customized deployments can engage the FWaaS experts to guide customization or even perform the setup.

Lastly, distributed locations often need their own dedicated appliances to secure the local network. Each of these appliances (virtual or physical) must be sized to current growth expectations and require future upgrades if the location’s needs increase. FWaaS scales automatically, and additional firewalls can be consistently and rapidly deployed with mouse clicks.

Maintenance

FWaaS providers take on the full responsibility of maintenance requirements and updates.

Local firewalls require alert IT teams to watch for the latest updates, manage network downtime, and correctly apply updates and patches promptly to prevent attacks.

Comparatively, FWaaS providers handle all maintenance in the background with minimal downtime using virtual appliance failover.

Additionally, local firewalls require constant updates for malware intelligence. The lists of the latest websites to block, additional malware signatures, or revised AI algorithms must be continuously obtained and added. Some processes can be automated, but some delays or downtime in the update process are inevitable. With FWaaS, providers keep all firewalls continuously and fully updated with the latest intelligence to block malicious websites and traffic.

Support

Power failures, device failure, and other network problems related to firewalls need to be managed and supported by internal teams. When moving to FWaaS, the customer and infrastructure support is offloaded to the vendor, which uses redundant architecture to minimize downtime and failure without any additional financial or staff resources required from the customer.

Economies Of Scale

As-a-service vendors buy larger architecture and hire a more expensive staff of experts than any single company could reasonably afford. The aaS vendors then sell it on a fractional cost basis to their customers.

For FWaas, customers gain the advantage of reduced prices and a shift from capital expenses (CapEx) to operating expenses (OpEx) by switching to a monthly or annual consumption subscription.

Moreover, FWaaS competes against NGFW and UTM appliances, which require significant upfront costs to acquire so often customers buy more than what they need to prevent purchasing additional equipment before the end-of-life of their expensive appliance. Switching to the FWaaS subscription model dramatically lowers initial costs and allows customers to pay only for the capabilities and capacity they need at any given time.

While some organizations might dramatically increase their use of firewalls with FWaaS and find their costs actually increase, typically, this will reflect an unmet need of the organization more than a failure to recognize cost savings.

Flexible Consistency

As-a-service solutions enable a select group of experts to configure a standardized solution that can be deployed through the internet to all parts of the organization.

Local firewalls often will be set up by local staff that may not have the best expertise in the organization or may apply inconsistent security policies or make mistakes in configuration or integration.

FWaaS allows the organization to deploy consistent security policies developed by the organization’s experts. FWaaS deploys with consistent configurations based upon preset templates. Organizations can decide when and how to deploy protections based on the processes and assets to protect and where in a cloud-based data chain to place protections.

Bottom Line: Advantages of FWaaS

FWaaS solutions provide profound advantages over traditional firewall solutions, even advanced UTM and NGFW appliances. However, potential customers may hesitate to adopt FWaaS because of:

• Perceived loss of control over the underlying hardware
• The concentration of too many security “eggs” in one basket
• The concern that firewall settings can be seen by FWaaS providers and become a security risk
• The concern that FWaaS technology is too new, and vulnerabilities have yet to be exposed and fixed
• The concern that FWaaS technology requires training on the subtle differences and settings for the technology compared to local firewalls
• The perception that current firewalls have many years of life in them and that cost savings might not be realized

These valid concerns will surely be addressed over time. Just as most other cloud solutions have gained acceptance, FWaaS solutions will prove to be an important feature for the operational and security architecture for most organizations as they move forward.

The following case studies can help companies see how network segmentation is being used by organizations in different industries.

5 network segmentation case studies

1. ServiceNow
2. Oil and Gas Refinery
3. Modern Woodmen of America
4. Clothing Manufacturer
5. Children’s Mercy Kansas City

1. ServiceNow

ServiceNow is a leading IT service management provider. Joel Duisman, the company’s principal IT security architect, recognized the need to improve an existing network segmentation strategy. He wanted to strengthen the protection of the company’s core services and domain controllers.

He chose service provider Illumio to meet those needs and moved forward with a phased rollout. The ServiceNow IT team appreciated how Illumio offered real-time visibility and gave consistently high protection in a multicloud environment.

“I sleep better at night knowing that Illumio closes the doors on potential attacks against our domain controllers. The demonstrable risk to the environment is noticeably lessened,” Duisman says.

Industry: IT services

Network segmentation product: Illumio Secure Cloud

Outcomes:

• Improved compliance with client audits
• Provided flexibility across cloud and on-premises data
• Enhanced protection of multiple systems without interruptions

2. Oil and Gas Refinery

Leaders at a major oil and gas refinery were experiencing unexplained data loss that made it more challenging to track emissions and otherwise stay in compliance with industry regulations. They hired the Champion Technologies team to troubleshoot after they couldn’t pinpoint the problem themselves.

Champion Technologies performed an in-depth site survey to compare the refinery’s current setup to best practices. Network segmentation was one of the recommended improvements. The providers also updated network components and provided monitoring software. These improvements give employees a better understanding of what’s happening on their network and ensure they get timely alerts to avoid regulatory fines.

Industry: Oil and gas

Network segmentation product: Champion Technologies provided Layer 2 network switches, Syslog software and segmented network

Outcomes:

• Stopped a known data loss problem
• Improved network security
• Tightened industry compliance

3. Modern Woodmen of America

Modern Woodmen of America is a fraternal financial services organization that aims to bring clarity through services, such as retirement planning and life insurance.

The organization uses a self-service portal that members can access anytime and anywhere. However, its traffic management system only handled virtual infrastructures, leaving a significant segment of traffic unmanaged. The company worked with service provider 27 Virtual to transition to VMware NSX-T and solve that problem.

“The inability to set up segmentation policies and east-west firewalling across dev, stage, and prod environments created a security gap that could be exploited by sophisticated threat actors,” says Zach Lotz, senior network engineer, Modern Woodmen of America.

“Once an attacker gained access, they’d have free reign to spread throughout the network.”

However, migrating to VMware NSX-T caused notable changes.

“The best part of segmentation with NSX-T is the ability to start broad — development versus production — and then go more granular as needed, even down to the application level,” Lotz says.

“This allows us to lock down our network to the point where only known traffic can communicate while everything else is blocked. Any anomaly is quickly identified and dropped.”

Industry: Financial services

Network segmentation product: 27 Virtual assisted the client in switching to VMware NSX-T for its network segmentation needs

Outcomes:

• A more modernized network infrastructure
• Secure 24/7 access to apps by staff and members
• Better security against unknown traffic

4. Clothing Manufacturer

A clothing manufacturer approached Burwood Group because of a need to get back into payment card industry (PCI) compliance. The service provider performed a network discovery process to learn more about the manufacturer’s apps and how people used them. The team suggested a network segmentation strategy after completing that assessment.

This change allowed the company to go from more than 1,600 security policies to 234. Network segmentation also made it easier to stay compliant and be more proactive about cybersecurity.

Industry: Manufacturing

Network segmentation provider: Burwood Group

Outcomes:

• Decreased security rules while reducing vulnerabilities
• Improved the company’s cybersecurity posture
• Minimized overall business risks

5. Children’s Mercy Kansas City

Children’s Mercy Kansas City is a 700-bed medical facility with a growing and varied collection of connected medical assets.

People also collaborated with multiple departments but lacked cohesive data security policies to follow when doing so.

Leaders chose Medigate by Claroty to enhance network segmentation capabilities and accommodate rapid growth. The product gave a risk-scored asset inventory to show people vulnerabilities within the facility’s connected devices.

“Medigate has been a necessary investment,” says Tarunjeet “T.J.” Mann, chief information security officer, Children’s Mercy Kansas City.

“They have provided the means for us to protect and monitor every connected device in a hospital at machine speeds.”

The solution also auto-generated security policies for each network segment, reducing potential threats and giving people better network oversight.

At a high level, NDR tools examine traffic for unusual or unexpected traffic and network behaviors that could indicate an imminent cybersecurity attack or data breach. NDR provides enterprises with the ability to broadly analyze network threats originating from many sources, including those that have no previous signature, including those appearing in cloud environments.

What Technology Is Used For NDR?

NDR products can utilize multiple technologies to analyze network traffic, but most frequently, machine learning and behavioral analytics. These technologies continuously analyze raw traffic and flow records to create models (or a “baseline”) of expected network behavior.

When NDR detects anomalous, unexpected network activity that goes against this expected baseline, these systems respond by transmitting a flag to network security teams for review. Depending on how filters are set up, the potentially analogous network traffic is either blocked or allowed to pass through and restricted or permitted after analysts review alert flags.

It is important to distinguish NDR as a network security tool from more traditional rules-based network security approaches like standalone SIEM (security information and event management), which strictly rely on predetermined rules.

Modern NDR analyzes raw network traffic logs versus “looking back” at the traffic that has already come across the network — as a result, modern NDR as a standalone product or used in conjunction with legacy network security tools can provide much more comprehensive coverage. NDR can also gather network traffic data from existing network infrastructure, including firewalls.

Some of the most noted NDR technologies:

• Darktrace
• Vectra AI
• Cisco Stealthwatch
• Awake Security Platform
• ExtraHop Reveal(x)
• Blue Hexagon
• RSA NetWitness Network
• IronNet IronDefense

What Is The Environment Of Network Detection And Response Software?

NDR is well-suited for enterprise networking environments, including those that serve a distributed workforce across multiple locations. NDR helps to centralize and manage the unwieldy task of monitoring huge amounts of network traffic flowing in and out of an enterprise network at lightning-fast speeds.

Typically, NDR software is installed at the local level but managed cybersecurity providers are increasingly offering “as-a-service” products that are hosted and managed remotely. In either case, SOC teams must be able to respond to alerts and make or recommend frequent adjustments to NDR settings.

NDR Software Core Functionality and Benefits of NDR Software

At its heart, NDR is intended to further protect enterprise networks that are already being monitored and protected in other ways. NDR is rarely used on a standalone basis — instead, it is a core component of a unified network security approach that adds technology like machine learning and other AI-driven enhancements to the mix.

Advanced NDR solutions give enterprises insights into network traffic not available through traditional security tools, from all directions, not just ingress and egress traffic. In effect, NDR can detect anomalous network traffic behaviors that remain inside a network, too, as well as traffic entering and exiting cloud environments.

True NDR can be an improvement over NTA tools that trigger an excessive amount of false positive flags. Enterprises may find it is worth the investment to partner with a company that has the capability and knowledge to access advanced AI technology, which is better able to sift true threats from likely false positive threats. This can be a marked advantage for SOCs where analysts are spending precious time sorting through mountains of false positive flags.

One significant benefit of bringing an NDR solution on board is its ability to help protect against ransomware, which has emerged as one of the biggest, most difficult-to-overcome cyberthreats of this century. Today’s ransomware attackers don’t even need to be tech-savvy to deploy attacks, thanks to the advent of Ransomware-as-a-Service (RaaS).

Ransomware attackers can also easily leverage AI to overcome various network security protections. A system that can establish a baseline of expected network behavior and then compare any network traffic against it has a significantly higher chance of overcoming and preventing ransomware in general (though no current product on the market can claim to completely eliminate this threat).

While most NDR products fall short of providing authentic real-time protection, near-real-time NDR is becoming the norm.

Bottom Line

Modern enterprise network security teams face a cyber security landscape where sophisticated attacks are constantly being refined by bad actors who are often well-versed in the latest tools available on the market. Enhanced NDR is much more robust than legacy tools leftover from years past and may well be an appropriate investment for future-facing enterprises, especially those with goals to scale in the coming years. These tools can be quite challenging for cybercriminals to overcome, making it all the more likely that a bad actor moves to an easier target.

Enterprises relying on legacy tools may not need to start from scratch in order to take advantage of the benefits of NDR. Many tools can be used in tandem with older systems, including those with on-premise hardware connected to cloud environments. These hybrid setups may benefit the most from the addition of complementary NDR.
