In the context of cyber resilience, a “Clean Room”, also known as a “Clean Room”, is an isolated and secure digital environment used to recover after a cyber-attack. This strategy can be part of a disaster recovery or IT contingency plan. Typically, this environment has the last secure copy of the organization's critical data and systems and is isolated from other systems to prevent the spread of malware or other security threats. In the event of a cyber incident, the organization can fall back to this “clean” environment to restore its systems without fear of compromise. Often, this approach is used to manage the risk of ransomware attacks, where an infection can spread rapidly across connected systems. It is important to emphasize that maintaining a “clean room” for cyber resilience involves an ongoing effort. Such an environment must be kept regularly updated to reflect current changes to the organization's systems and data. This ensures that, should the need arise, operations can resume with as little disruption as possible.
