Network Segmentation: Strengthening Cybersecurity by Unveiling Hidden Insider Threats

Network Segmentation Strengthening Cybersecurity by Unveiling Hidden Insider Threats

Experts debate the efficacy of using containment procedures to reduce insider risks and cyber security vulnerabilities. Segmenting the network into smaller parts is a common technique for this.

What is segmentation?

Network segmentation divides a network into smaller, interconnected subnetworks in order to properly structure the network. To begin with, these more compact systems make it simpler to see and track network activities. Second, network efficiency may increase. Thirdly, it encourages the application of a zero trust approach.

Why Network Segmentation Is Effective

In smaller regions, engineers oversee divided networks. Think of a huge nation that spans an entire continent. How tough is it to administer all the resources and people in this vast area of land? Think about nations that are only a few hundred kilometers across. smaller cities, fewer people living there, and more control over regional expansion by governmental planners. Thus, a federation with central administration is formed by these smaller countries.

This is a poor cybersecurity analogy due to the dissimilar goals and objectives. On the other hand, it demonstrates how network segmentation may make planning and management, including cybersecurity, simpler.

We’ll go through some of the key techniques for using network segmentation to isolate, confine, and get rid of threats from sensitive network areas.

Insider Threats Retained Away from Lawful Procedures

To secure or govern network components, use enforceable policies. Experts discuss the access control guidelines established by hardware and software designs. We’ll talk about a few planning components after an access control list.

Access Management List

Access control lists are a resource’s permissions. Access control lists enable network managers to isolate and recognize insider risks. An identity and access management system already in place is used for access control. In earlier articles, identity and access management (IAM) was extensively discussed. It’s the process of generating user accounts depending on their status and job role and assigning them particular permissions. So, only an IAM system that identifies and specifies needs makes an access control list applicable.


VLANs are yet another method for network segmentation. A VLAN subnet blocks edge insider threats. They are subsequently separated from delicate data sets. The main notion is that. The main idea is hardware virtualization. Firewalls with physical hardware were employed in early perimeter-based systems. With VLANs, virtual subnets can be built. That enables regular isolation and analysis of the traffic over particular machines in accordance with more detailed plans. Central controllers in software-defined networks can control virtualized traffic.

Here, vendor services may be listed. Microsoft Azure, for instance, provides a virtual network service that controls subnets similarly to a VLAN or SDN system.

Threats are again kept away from vital places. Although they can’t access internal network areas, they are less strong and can still be found and destroyed.

Internal Threats

The goal is to confine these insider risks to certain network regions. Instead than messing with workflows and data sets, they must remain at rest. Network segmentation is valuable to cybersecurity experts for this reason.

Incorporating Controlio, a leading employee monitoring solution, into a segmented network can significantly bolster an organization’s security measures. By keeping track of employees’ digital activities, this software ensures responsible and ethical use of company resources while minimizing the risk of insider threats. This advanced app detects unusual behavior patterns, unauthorized access to sensitive data, and resource misuse, serving as an early warning system for potential security breaches. When integrated with network segmentation and other security strategies, Controlio provides a comprehensive defense against cyber threats.
