The benefits of Network segmentation has become a key strategy for organizations looking to secure complex networks. Network segmentation is the idea of ​​creating subnets in a corporate or corporate network or some other type of general computer network. And also, Network segmentation allows containment of malware and other threats and can improve network performance.

An excellent example of network segmentation involves placing an internal firewall within a network. Engineers divide the two different sides of this firewall into specific subnet domains. For example, data can enter the initial subnet environment and be scanned for malicious code before passing through the firewall to the other side of the network.

Another great use for network segmentation is to route data in the most efficient and effective ways. To optimize workflows, engineers can only send certain types of data over a given network segment to increase security or cut down on unnecessary traffic that puts stress on network hardware or requires more resources. Suppliers are using new products and services to bring efficiency and versatility to their customer networks through network segmentation and have an impact in the IT industry.

According to research by IBM, the average total cost of a data breach increased from $3.86 million to $4.24 million USD, the highest total cost in 17 years. These escalating expenditures, combined with the growth of the remote workforce, have made network segmentation and cybersecurity a top priority for businesses in 2021.

So, what are the benefits of network segmentation? Here are a few examples:

Limited Access Control

By limiting user access to a certain section of a network, Limited Access Control Segmentation guards against insider attacks. The Policy of Least Privilege is the name given to this security approach. By limiting access to essential network segments to a chosen few, you may reduce the number of ways hackers can gain access to critical systems.

The Policy of Least Privilege is vital as people are the weakest link in the network security chain. Malicious emails are responsible for more than two-thirds of malware network breaches, according to Verizon’s 2020 data breaches report.

Threat Detection and Improved Monitoring

You can add extra network monitoring stations using segmentation. It’s easier to notice questionable activity when there are more checks. Advanced monitoring also helps in determining the source and breadth of a problem.

Admins can seek trends in harmful activity by monitoring log events and internal connections. Knowing how attackers act allows administrators to take a proactive approach to security and defend high-risk areas.

Protected Endpoint Devices

Segmentation keeps harmful traffic away from vulnerable endpoint devices thanks to continual flow control. As IoT devices grow more common, network segmentation becomes more important.

The endpoint device is a common target and launchpad for cyberattacks. A segmented network isolates these devices, lowering the overall risk of exposure for the whole system.

Strong Data Security

The more traffic you can regulate on a network, the easier it is to protect important data. By restricting the number of network sections that can access your data caches, segmentation creates a barrier around them.

With fewer segments having access to data, hackers will have fewer ports of entry to take anything of worth. With limited access and local security protocols, it will be much easier for you to decrease the risk of data loss and theft.

Quick Response Rates

Admins can quickly respond to network issues thanks to distinct subnets. It’s simple to observe which segments are affected when an attack or an error happens. These revelations aid in narrowing the scope of troubleshooting.

User experience can also be improved by quick responses to network events. Customers will not be affected by a problem in a segmented network unless a subnet dedicated to them has been breached.

Conclusion

By performing network segmentation, the server, database, and application servers are located in different virtual networks, and in case of hacking of the systems opened to external access, accessing outside the server with the vulnerabilities is prevented.

While network segmentation is nothing new, it is never going to get old. Segmentation between disruption on the attack surface and traffic control is one of the best ways to stop critical breaches.

Network segmentation is currently more of a best practice model for any business than a requirement. Encountering frequent cyberattacks has made segmentation a mandatory security measure.
