It just takes one glance at the headlines of any major newspaper to see the devastating effects of a cyberattack. 

Unfortunately, the steps organizations have taken in response range from putting their heads in the digital sand to implementing a sophisticated series of security tools and best practices. 

In recent years, one of the most effective techniques includes making a shift toward a Zero Trust approach, which is built upon the principle that no entity—user, app, service, or device—should be trusted by default. Or, more simply, trust is established based on the entity’s context and security policies, and then continually reassessed for every new connection, even if the entity was authenticated before.

Given these benefits, it’s not surprising that a recent survey revealed that more than 60% of companies view a Zero Trust strategy as paramount. However, progress toward implementation, which depends on network segmentation for effective policy enforcement, points to a less promising state: Only 19% of the companies in the survey have micro-segmentation in place.

This gap is particularly concerning given the business importance of protecting critical assets and data, which Zero Trust does. Since many companies that have deployed micro-segmentation are just using it for visibility, the number of companies prepared to put a Zero Trust strategy into practice may be very small indeed.

Let’s explore the “Why?” and “What now?” behind this gap.

Why Companies “Roll the Dice” Instead of Following Advice

These are some of the most common reasons for a slow or missing shift toward network segmentation:

1. It’s too complicated.

Early methods that enabled segmentation required a shift in network infrastructure, involving the creation of new VLANs, subnets, and even re-IP addressing. This process could disrupt existing applications and requires meticulous documentation to ensure changes are made thoughtfully. 

2. It’s too expensive.

Many data center micro-segmentation projects are really visibility projects disguised as security. Visibility requires large-scale deployment, which can limit micro-segmentation’s cost-effectiveness for a critical workload. Also, to be effective, controls need to be turned on.

3. It faces user pushback.

If micro-segmentation is not deployed carefully, users could become frustrated when resources or applications they used to be able to access become inaccessible or experience minor disruptions. 

4. It creates Zero Trust integration headaches.

Micro-segmenting a workload provides a good starting point for Zero Trust, but many vendor solutions leave customers far from the finish line. Customer IT teams still have the unenviable task of figuring out how to enforce identity-based policies for all network packets.

How to Position a Micro-Segmentation Project For Success

Micro-segmentation has been around for some time, so even its name can come with preconceived notions, such as those mentioned above.

However, micro-segmentation implemented with the right tools is very different: It removes the need to technically (or even physically) restructure a network, instead providing the opportunity to put policy enforcement in front of each workload. This method allows legitimate traffic to move freely but stops malicious lateral attacks in their tracks.

In other words, with the right tools, planning, and preparation, micro-segmentation can put organizations and security teams on a solid path to Zero Trust. 

Here are some ways to ensure your micro-segmentation project can deliver:

Think about the big picture.

Visibility is important, but executive teams and boards buying into a micro-segmentation project expect it to deliver tangible security benefits. That means you can’t stop at visibility—you also need to turn on the controls.

Think about zones.

Micro-segmentation for Zero Trust should support the creation of virtual network zones to contain assets and devices. These define the implicit trust zone for a Zero Trust Architecture and allow you to easily target policies at a large set of similar workloads, rather than managing access to thousands of individual servers.

Think small.

Focus on a few critical applications or assets with real business impact, and use the project to segment and protect them. Achieving 100% Zero Trust for one project is far more impactful than achieving 5% for 1,000 projects, and you can avoid asking your CFO to foot the bill for a traditional “boil the ocean,” large-scale micro-segmentation project.

Think holistically.

Blocking access to an asset with micro-segmentation implies you also have to take responsibility for providing access to authorized users and software. On-premises and remote users may be impacted differently, so prioritize solutions that integrate and address the access challenge to minimize user disruption and ensure a smoother transition to a more secure network environment.

Tips for Implementing Micro-Segmentation

When micro-segmentation is properly implemented, it can be a big security (and operational) win for your organization.

So how can your organization make the shift successful?

Although every organization’s requirements, needs, and environment are unique, I’ve found some common best practices that can guide your journey toward implementing micro-segmentation:

Crawl, walk, run.

Start with a proof of concept (POC) using a test application to gauge the impact of micro-segmentation. Gradually expand the scope to include more applications, prioritizing those deemed most critical.

Choose a POC application that covers your use cases.

Selecting a POC application that reflects the diversity of your use cases ensures that the micro-segmentation strategy is comprehensive and addresses the unique needs of different parts of your organization. For example, how will your chosen segmentation method support application access from authorized users in the office or working remotely?

Consider all types of assets you need to protect.

Ensure that your micro-segmentation strategy accounts for all types of assets, including Internet of Things (IoT) and operational technology (OT) devices. Collaboration with vendors that offer native support for these devices is crucial for a holistic approach to security.

Consider where your assets are located.

Assets may be distributed across various locations, including branch offices and cloud environments. Integrating micro-segmentation with an overlay network or software-defined networking (SDN) can simplify management and enhance security across all locations.

Make Micro-Segmentation Part of Your Network

At first blush, a move to Zero Trust—and the micro-segmentation that enables it—can seem complex and time-intensive.

Fortunately, new tools and platforms, such as overlay infrastructure, are available to more easily implement a Zero Trust framework. These tools can eliminate the common hurdles and hangups while minimizing disruptions to your systems, users, and budget. 

My final thought? Test the waters with a POC application and keep your specific use cases in mind, and you will be well on your way to better cybersecurity.

The UK government’s annual Cyber Security Breaches Survey has revealed that 50% of businesses have faced a cyberattack or breach in the past 12 months. It’s a dangerous world out there, and one small slipup can be extremely costly. Organisations are doing their best to reinforce their digital walls, but it’s a constant arms race; for every security innovation, a new exploit is deployed.

Even as businesses invest in tools to bolster their frontline defences, attackers are seeking other, more creative ways to get in. A prevalent example is Ransomware as a Service (RaaS) operations. In these attacks, groups such as LockBit help paying customers deploy ransomware tools to extort businesses. This gun-for-hire delivery model massively expands the number of malicious actors who can use ransomware; in addition to being a way for cybercriminals to make a quick buck, ransomware can become a tool of revenge, competition, and corporate sabotage.

Ransomware is a particularly cruel form of attack; it’s direct, personal, and blunt. It forces the victim to respond rather than silently removing data or payment information. Though the damage caused may be much the same in the end, for IT teams and senior decision-makers, it’s a deeply stressful process. Do you negotiate with your attacker? Pay to get your data back, with no guarantee they’ll comply? Risk being marked as a soft target for other attackers?

Furthermore, the problem is getting worse. Ransomware attacks have become increasingly prevalent in recent years. In 2023, they increased 95% compared to 2022, striking organisations of any sector and size. There’s no typical victim; ransomware can target any organisation. That means all organisations need to take steps to reduce the risk of a successful ransomware attack.

Here are five key actions that all organisations should consider to protect themselves from RaaS:

1. Train your employees well

The first step to preventing ransomware attacks is to train your staff on cybersecurity best practices and conduct red team exercises, which are simulated attacks that give your employees the chance to learn the best practices by putting them into action. Additionally, you can ensure employees stay up to date on your organisation’s current cybersecurity policies by conducting security skill assessments on a regular basis. Since ransomware attacks are usually carried out through social engineering tactics (which trick people into clicking links, opening files, or sharing login credentials), employees must be educated on how to spot phishing emails or malicious websites so that they will be less likely to unwittingly grant hackers access to company systems.

2. Control user access intelligently

Another way to reduce the risk of ransomware attacks is to limit access and permissions to only what users need. Role-based access controls can significantly reduce the possibility of a data breach. Following a Zero Trust approach by using 2FA or MFA enhances endpoint security because ransomware actors can’t gain access without secondary authentication. Automated, data-driven ID management systems are becoming increasingly intelligent, allowing for access to be withheld on the basis of the user’s geographical location, their behavioural patterns, the time of day, and even physical data like their typing speed.

3. Back up your backups

Backing up all your important files frequently could act as a lifesaver if you suffer a ransomware attack. You won’t lose access to confidential information and can resume operations with minimal downtime. You may even avoid having to pay the ransom, although having a backup doesn’t stop attackers threatening to sell the personally identifiable information they’ve obtained. It’s best to make backups on external drives and cloud servers and to follow the 3-2-1 backup rule: Have three copies of your data on two different media with one saved off-site.

4. Update regularly and configure firewalls

Systems or software that aren’t periodically updated or patched are highly vulnerable to attacks, and hackers target them to penetrate networks and access sensitive data. Keeping your applications, systems, servers, and antivirus solution up to date and equipping yourself with an extended detection and response tool can help prevent attacks. You can go a step further in protecting your network by configuring firewalls that filter out and block suspicious activities in the first place. Also, you should consider investing in an endpoint protection platform because it’s often the best bet when it comes to defending against viruses and malware, including ransomware.

5. Segment your network

Once a system is infected, the ransomware spreads like wildfire into other connected systems. Segmenting your network into various subnetworks helps prevent the ransomware from entering the main network and gives IT security teams the needed time to take remedial action.

Ransomware is a highly dangerous attack type that puts organisations’ customers, reputations, finances, and even viability at risk. With the right defences in place, and with employees properly prepared to spot and evade social engineering attacks, businesses can maximise their chances of avoiding a successful attack and stopping ransomware in its tracks.

Network Security protocols are designed to safeguard computer networks from unauthorized access, data breaches, and other cyber threats. And here are some common types of network security protocols:

 Secure Sockets Layer (SSL) / Transport Layer Security (TLS): SSL and its successor TLS are cryptographic protocols that provide secure communication over a computer network. They are commonly used to secure web transactions, such as those conducted in online banking and e-commerce.

IPsec (Internet Protocol Security): IPsec operates at the network layer and is used to secure Internet Protocol (IP) communications. It can provide encryption, authentication, and integrity verification, making it widely used in Virtual Private Networks (VPNs).

Wireless Protected Access (WPA) / WPA2 / WPA3: These are security protocols designed to secure wireless computer networks. They are used to encrypt data transmitted over Wi-Fi networks and protect them from unauthorized access.

Firewall Protocols (e.g., TCP/IP, UDP): Firewalls use various protocols, such as TCP/IP and UDP, to control and monitor incoming and outgoing network traffic. They can be hardware or software-based and act as a barrier between a trusted internal network and untrusted external networks.

Intrusion Detection System (IDS) / Intrusion Prevention System (IPS): While not exactly protocols, IDS and IPS systems use various techniques to detect and prevent unauthorized access and attacks. They analyze network traffic for suspicious patterns or anomalies.

Virtual Private Network (VPN) Protocols (e.g., PPTP, L2TP/IPsec, OpenVPN): VPNs use different protocols to create a secure, encrypted tunnel over an existing network. Protocols like PPTP, L2TP/IPsec, and OpenVPN are commonly used for establishing secure connections over the internet.

Simple Network Management Protocol (SNMP): SNMP is a protocol used for network management and monitoring. While its primary purpose is not security, it plays a role in network security by allowing administrators to monitor and manage network devices.

Secure File Transfer Protocols (e.g., SFTP, SCP, FTPS): These protocols provide secure methods for transferring files over a network. They often use encryption and authentication mechanisms to protect data during transfer.

DNS Security Extensions (DNSSEC): DNSSEC is a suite of extensions to DNS that adds an additional layer of security by digitally signing data to ensure its integrity and authenticity.

Pretty Good Privacy (PGP) / GNU Privacy Guard (GPG): PGP and GPG are used for securing email communications. They provide encryption and digital signatures to ensure the confidentiality and authenticity of email messages.

It’s important to note that new security protocols may emerge over time, and the landscape of network security is continually evolving. Always ensure that your network security measures are up to date with the latest industry standards and best practices.

Network-connected wrenches used globally are now at risk of exposure to ransomware hackers, who can manipulate their functionalities and gain unauthorized access to the connected networks, according to experts.

Research conducted by Nozomi reveals that the Bosch Rexroth Handheld Nutrunner, a network-connected wrench, displays vulnerabilities that could potentially allow hackers to disrupt entire networks or manipulate operations in production facilities, leading to work sabotage.

Bosch network wrenches, widely utilized in manufacturing and service stations worldwide, pose a significant risk, as any flaw in these tools could jeopardize entire facilities, potentially even causing fires.

The Nozomi report affirms that these Bosch devices, operating on NeXo-OS, can be manipulated through a web-based online management interface using a Wi-Fi module, making them susceptible to the spread of malware such as ransomware.

The research findings were brought to the attention of the German manufacturing and engineering tech company, Bosch, which has acknowledged the situation and is actively working on developing a solution.

A detailed explanation of these vulnerabilities in network-connected wrenches was provided in a paper released by Dan Goodin of Ars Technica. It emphasizes that similar vulnerabilities exist in wrenches from other companies like Cisco, Datto, HPE, and Juniper Networks, potentially serving as avenues for the spread of ransomware if their vulnerabilities are left unaddressed.

In an era where cyber threats continue to evolve in sophistication, organizations are increasingly turning to advanced security measures to protect their digital assets. One such strategy gaining prominence is micro-segmentation of networks, a powerful approach that proves invaluable in fortifying defenses against the pervasive threat of ransomware. This article explores the significance of micro-segmentation and how it contributes to a robust defense posture against ransomware attacks.

Understanding Micro-Segmentation:

Micro-segmentation involves dividing a network into smaller, isolated segments, each with its own set of security protocols and controls. Unlike traditional network security measures that rely on perimeter defenses, micro-segmentation operates within the network, creating barriers that restrict lateral movement for cyber threats.

Key Components and Benefits:

1.Isolation of Critical Assets: Micro-segmentation allows organizations to identify and isolate critical assets, such as sensitive databases and key servers. By segmenting these assets from the broader network, the impact of a potential ransomware attack is limited, preventing the lateral spread of malicious activity.

2.Reduced Attack Surface: By dividing the network into granular segments, the attack surface available to potential threats is significantly reduced. This makes it more challenging for ransomware to propagate throughout the network, as it must overcome multiple barriers rather than exploiting a single point of entry.

3.Enhanced Access Control: Micro-segmentation enables organizations to implement stringent access controls. Only authorized users and devices are granted access to specific segments, minimizing the risk of unauthorized access or lateral movement by ransomware.

4.Improved Incident Response: In the unfortunate event of a ransomware incident, micro-segmentation facilitates a more focused and efficient incident response. Security teams can quickly identify the affected segments, isolate the compromised systems, and prevent further damage before it spreads.

5. Adaptability to Network Changes: Micro-segmentation is adaptable to dynamic net-work environments. As organizations scale or reconfigure their networks, micro-segmentation can be adjusted to accommodate changes, ensuring continued protection against evolving ransomware tactics.

Case Studies and Real-World Examples:

Several organizations have successfully employed micro-segmentation to defend against ransomware. Case studies showcase instances where this strategy has prevented the lateral movement of ransomware, limiting the scope and severity of attacks.

Conclusion:

As ransomware threats persist in their sophistication, the implementation of advanced cybersecurity measures becomes imperative. Micro-segmentation stands out as a proactive and adaptive approach, providing organizations with a powerful tool to enhance their defense mechanisms. By isolating critical assets, reducing the attack surface, and improving access controls, micro-segmentation plays a pivotal role in safeguarding against ransomware attacks, ultimately ensuring the resilience and integrity of digital infrastructures.

It is not accurate to say that 5G networks are completely immune to cyber attacks. Like any other network, 5G networks are vulnerable to various types of cyber attacks, such as distributed denial-of-service (DDoS) attacks, phishing attacks, and malware infections.

However, 5G networks do offer some unique security features that can help mitigate the risks of cyber attacks. For example, 5G networks use advanced encryption technologies to protect the confidentiality and integrity of data transmitted over the network. 5G networks also use soft-ware-defined networking (SDN) and network function virtualization (NFV) technologies to create a more flexible and dynamic network architecture, which can help identify and respond to security threats more quickly.

In addition, 5G networks employ a concept known as network slicing, which allows network operators to create multiple virtual networks on a single physical network infrastructure. This can help improve security by isolating different types of traffic and applications, and providing more granular control over network access and usage.

Furthermore, 5G networks are designed with security in mind from the outset, incorporating security features into the network architecture and protocols. This can help reduce the risk of vulnerabilities and exploits being discovered and exploited by cyber attackers.

While 5G networks are not immune to cyber attacks, the security features and design principles of 5G networks can help reduce the risk of cyber attacks and improve the overall security and resilience of the network. It is important for network operators and users to continue to be vigi-lant and proactive in protecting against cyber threats, and to stay up-to-date on the latest securi-ty technologies and best practices.

Satellite networking is a great asset for many use cases. For example, it is critical in building a reliable global network that operates in adverse and DDIL (Denied, Disrupted, Intermittent, and Limited) conditions. This is especially true in defense use cases, where you must operate under challenging conditions, including lack of wired networks, unavailability of line of sight, or jamming.

To optimize satellite multi-orbit deployment networks, end users can integrate different types of links to leverage the benefits of the available satellite orbits: MEO, GEO, or LEO links. To achieve this, they need solutions that help them implement their multi-orbit networks with full automation. A secure SD-WAN solution provides a reliable approach and excellent user experience. SD-WAN creates a virtual (overlay) network on top of the physical infrastructure using a software-defined control plane. This abstraction grants greater flexibility and control over the traffic.

Today’s mobile workforce and distributed applications deployed in hybrid multi-cloud environments are driving factors for the adoption of Secure Access Service Edge (SASE) architectures, and SD-WAN is a fundamental part of SASE. However, satellite networks have unique characteristics that require tailored solutions. There are critical capabilities that network administrators should look for while implementing an SD-WAN network using satellite links.

The first critical capability to consider is Quality of Service (QoS). Network administrators configure classification systems that match the critical traffic and assign it to a high-priority queue. When congestion arises, critical traffic takes priority. But in satellite networks, conditions are always changing, so congestion might change without notice. For this reason, an ideal SD-WAN solution for satellite networks should be tightly coupled to QoS.

Networks that operate using limited satellite bandwidth benefit from a closed loop between an SD-WAN system and the RF modems. For example, the gateway modem could signal to the SD-WAN detection of degradation in available bandwidth. This triggers the SD-WAN to adapt to the situation and adjust the interface shapers. Any SD-WAN solution suitable for satellite links must provide a flexible programmable capability to dynamically adapt to network conditions. It should support automation via open API integration. In a multi-orbit deployment, users need distinct QoS treatment for every link. This closed loop is an effective way of achieving it.

Traffic Engineering is an indispensable capability for multi-orbit links. It enables users to bond multiple satellite connections to provide increased bandwidth and redundancy. In a multi-orbit scenario, an ideal SD-WAN solution must be able to failover seamlessly from one link to another. Since conditions of satellite links are constantly changing, a quicker failover to an alternate link guarantees better user experience. The ideal solution should also support asymmetric paths wherein uplink and downlink traffic are sent via different satellite links. This is useful when a certain link has limitations in one direction. By implementing this capability, available links can be fully utilized even if they are impaired in one direction.

To complement the Traffic Engineering features, users should also explore SD-WAN solutions that provide advanced monitoring capabilities, including real-time and historical information used for traffic routing decisions. Typically, satellite links are part of one segment in a multi-segment network. Having visibility into end-to-end performance of the entire segment via advanced SLA measurement techniques is a very useful feature for the optimal utilization of the links.

Despite having multi-orbit redundancies, we can never fully avoid a situation where the only available option to forwarding traffic is a suboptimal link. TCP optimization capabilities like BBR, Hybla, SACK, and Recent Acknowledgement help in mitigating this, especially for links with high latency or loss. However, this does not help for UDP-based applications. In those cases, administrators should rely on packet remediation techniques like Replication and FEC. Since these capabilities add to the byte counts sent over the links, the SD-WAN solution must support dynamic activation of these features based on network conditions, only activating them when necessary.

Finally, consider how to reduce network overhead by the SD-WAN due to the addition of extra bytes to the headers. These extra bytes typically carry information about the overlay tunnel. Satellite connectivity is expensive, so every byte that is not spent in goodput has an adverse effect on the budget of the project. This overhead can be reduced by implementing a tunnel-less overlay, a very critical capability when selecting your SD-WAN solution for the satellite links. Tunnel-less in an SD-WAN solution makes the network more scalable and bandwidth-efficient, eliminating fragmentation of packets and providing better security. Some use cases that drive tunnel-less overlay include satellite, maritime, and federal networks that leverage NSA High Assurance Internet Protocol Encryption (HAIPE) or Commercial Solutions for Classified (CSFC)-based architectures.

SD-WAN can revolutionize satellite-based communications, particularly for mobility and DDIL use cases. To be a suitable SD-WAN solution, the system needs to provide fully integrated routing, a full stack of security, and support of the above-mentioned critical features. It must provide full visibility into network and security events with the capability to automatically execute optimal policies based on application and current network conditions.

National Security Agency (NSA) has issued a report that has outlined cybersecurity threats related to 5G Network Slicing. The cyber alert was issued to companies involved in the business of offering applications and services related to the high-speed wireless internet broadband services.

5G Network slicing is nothing but sharing resources aligned with the same physical infrastructure by multiple resources. The slicing of network can be allocated based on the specific needs of applications and use case of customers.

NSA wants the network operators to follow basic security standards that allow to mitigate threats associated to threats like Denial of service, man in the middle attack and configuration related troubles.

Security concerns related to network split were raised by Cybersecurity and Infrastructure Security Agency (CISA) in September 2020 and experts were pressed into service to ease the risks on a technical note.

As architecture plays a crucial role in the espousal of new technologies, certain companies like Huawei, ZTE and Hikvision were imposed with a trade ban in whole of united states. Meaning, the products and services sold by this firm will not be entertained anymore in America.

NOTE 1- 5G plays a vital role in the prevalence of technologies like autonomous cars and IoT and so securing the network becomes extremely crucial, especially when adversaries are indulging in cyber warfare.

NOTE 2- Business firms should be extremely cautious when countries like Russia, China and North Korea are waiting for a chance to exploit the critical infrastructure of other nations for own benefits. And as the future looks bright for 5G adoption across the world, the threat vulnerability might also double or triple within no time.
