Introduction

It isn’t enough to simply secure your system. You also need to plan for when system elements are compromised, whether through accident or by the actions of a malicious actor. When this happens (and it will), it is necessary to be able to quarantine those system elements until the problem is resolved.

For critical applications that cannot be brought down due to a security issue, you need to be able to perform this action dynamically, without reconfiguring and restarting the entire system. Simply revoking certificates of compromised elements isn’t enough. You need to make sure that all communication channels created using those certificates are closed down as well.

Multiple parts of your system have to work together to do this well, from threat detection to certificate management to the actual communication between devices. This type of integration can be challenging and it is important to do it right, as mistakes here can keep security issues from being handled on time and properly.
