A cyber attack can be devastating for a business. In many cases, the company is left completely reeling after an attack. However, there are steps that you can take to help improve your cyber resilience and survive a cyber attack. One of these steps is to implement segmentation into your network. Segmentation can help reduce the “blast radius” of an attack and make it more difficult for the attacker to move laterally throughout your network. In this blog post, we will discuss how segmentation can help improve your cyber resilience and survive a cyber attack.
When it comes to cyber attacks, businesses need to be prepared. An attack can happen at any time and often leaves the company completely unprepared. This is why it’s important to have a good cyber resilience plan in place. A big part of being prepared for a cyber attack is having a network that is segmented.
Segmenting your network essentially means creating different “zones” within your network. These zones can include a guest network, a production network, and a DMZ network. By having these different zones, you can help control the spread of an attack. If an attacker does manage to get into one of the zones, they will be isolated from the rest of the network and will not be able to move laterally as easily.
In many cases, businesses have flat networks, which means that there is no segmentation in place. This leaves the entire network vulnerable to an attack. If an attacker does manage to get into the network, they can easily move laterally throughout the network and affect a large number of systems. This is often how ransomware attacks work. The attacker will encrypt the data on the systems in the network and then demand a ransom from the company in order to decrypt the data.
However, if you have a segmented network in place, the attacker will not be able to move laterally as easily. This can help limit the damage that they are able to do and make it more difficult for them to encrypt all of the data on the network. Additionally, if you have backups that are accessible from the production network, they will be less likely to be compromised or destroyed if the attacker is only able to affect one segment of the network.
Overall, segmentation is a key part of having a good cyber resilience plan. By segmenting your network, you can help reduce the “blast radius” of an attack and make it more difficult for the attacker to move laterally throughout your network. This can help limit the damage that they are able to do and make it more difficult for them to encrypt all of your data. If you don’t have a segmented network in place, now is the time to implement one. It could potentially save your business from a devastating cyber attack.
