Today we live in a digital world where even big task can be done in fraction of seconds. It has made our life so easy and comfortable. But do you know network breach is an inevitable risk online. It is almost certain that cyber attacks will happen and that is why it is necessary for every network to withstand a break in. Today cyber security mechanism stood out as very effective in limiting the damage in case of a network breach and that cyber security mechanism is network segmentation.
Segmentation provides the most efficient and effective defense of all forms of network security.
Security benefits of network segmentation include the following:
- Strong Data Protection
The more you monitor traffic on a network, the easier it is to protect critical data. Segmentation creates a wall around your data caches by restricting the amount of network parts that reach them.
- Better Access Control
Enable users to have access to unique network resources only.
- Threat Containment
Whenever any hacker tries to breach a segmented network, he will be contained within a single subnet. For the hacker it will take to break into rest of the system.
- Improved Performance
With fewer hosts per subnet, local traffic is minimized. Broadcast traffic can be isolated to the local subnet.
- Better Containment
If a network problem arises, the effect is confined to the local subnet.
Network Segmentation Best Practice
- Be Cautious of Over-Segmentation
Although the separation of individual properties on your network is an excellent cyber security policy, there is too much segmentation. If the network is too segmented, it can be more difficult to control and even impact the efficiency of the network — which affects employee productivity. Your security in depth approach should also take into account how important each resource you are isolating, how sensitive data and systems are to that endpoint, and how much network traffic that resource is required to manage. Doing so will help you balance the value of the protection you are implementing against the value of the resource.
- Conduct Regular Network Audits
Always do frequent network assessments to detect any new assets that have been added to the network as it is one of the most important network security practices for closing security loopholes in your organization. So, make sure to do it regularly.
