What must be logged for individuals with authorized unescorted access into a Physical Security Perimeter?

In the context of NERC Critical Infrastructure Protection (CIP) v7 Standards, it is essential to maintain thorough documentation related to individuals who have authorized unescorted access into a Physical Security Perimeter. This is critical for ensuring accountability, tracking access, and preserving security integrity.

The correct answer highlights the requirement to log entry date and time alongside individual identification. By documenting the date and time, organizations can maintain an accurate record of when individuals enter and exit sensitive areas, which is crucial for incident investigations and maintaining an audit trail. Recording identification ensures that the specific individual can be traced, which is important in enhancing the overall security posture of the facility.

While other choices may seem relevant, they do not encompass the full requirements set out by NERC CIP standards. Logging a visitor's purpose may provide context but does not satisfy the requirements regarding access accountability. Similarly, logging personal information alone might not convey the necessary access monitoring needed for security purposes. Simply recording the entry date lacks the specificity and depth needed for a robust security protocol, as it doesn't connect the access to an individual. Thus, comprehensive logging of both temporal details and identification is crucial under the CIP requirements.
