What is the focus of Requirement R4 in relation to Transient Cyber Assets?

Requirement R4 focuses on the implementation of documented plans concerning Transient Cyber Assets. This requirement emphasizes the need for entities to have procedures that clearly outline how to manage these assets securely. Transient Cyber Assets, which are often temporarily connected to critical systems, need structured processes to control their access and ensure they do not introduce vulnerabilities into the Protected Cyber Assets.

Having documented plans ensures that there is consistent and repeatable guidance for personnel on how to deal with these transient assets, reducing the risk of unauthorized access and possible cyber incidents. Such plans typically cover aspects like identification, access controls, monitoring, and the removal of these assets after use.

The focus on documented plans distinguishes this requirement from others that may address aspects of access authorization, budget considerations, or physical security, as those elements do not specifically pertain to the management and security processes for transient cyber assets.
