(3) Documentation must be maintained, such as manuals and user guides, describing the systems in use and the operation, including hardware.

(h) Remote access.

(1) Agents may be granted remote access for system support, provided that each access session is documented and maintained at the place of authorization. The documentation must include:

(i) Name of agent authorizing the access;

(ii) Name of agent accessing the system;

(iii) Verification of the agent's authorization;

(iv) Reason for remote access;
