Once malware or other elements of compromise are identified, care must be taken to remove them completely from the network. Tools that modify shared libraries or files, modify applications or code, or exploit existing software—a technique known as “living off the land”—can make identifying and removing all attack elements particularly challenging. As a result, action must be taken quickly to prevent the attacker from compromising the system again. This is accomplished by using the information gained from previous steps and immediately addressing the issues that led to the breach, such as reconfiguring the device, installing a missing patch, or resetting compromised credentials.
has been contained and resolved, recovery must be performed using correct backups. Recovery teams must be able to return critical systems to working order as quickly as possible. IT teams should also be aware that embedded threats can be difficult to completely eliminate, especially those designed to avoid detection, so it is always a good idea to increase security monitoring in the weeks following a breach to ensure that the threat has been completely eliminated.

This is a longer process of remediation that will reduce the likelihood of an incident happening again. Lessons learned should be incorporated into security policies, points of compromise should be eliminated, hidden malware should be found and removed, and the same weaknesses in other parts of the network should be strengthened.
This is where you may need to take a hard look not only at your existing security tools and systems, but also at your people and processes. What security elements are missing that could have detected a breach but didn’t? What processes were broken? What skills were missing that could have expedited breach detection or recovery? This may mean adding additional tools to your security architecture, upgrading or replacing systems that failed, and providing additional training to critical security personnel.
