Refer to the information below to answer the question. A large organization uses unique identifiers and requires them at the start of every system session. Application access is based on job classific

Access control logs must contain the time of access in addition to the unique identifier because audit logs require timestamps to establish a chronological record of who accessed what and when, which is essential for detecting violations, conducting forensic investigations, and satisfying independent access control reviews. Without timestamps, the identifier alone cannot prove when a session occurred, making the log insufficient for accountability and compliance purposes.

Security classification pertains to the sensitivity level of data or resources, not a required field in access control logs alongside user identifiers; it is an attribute of the resource, not the session event.

While denied access attempts are valuable for security monitoring, they are a category of log event rather than a mandatory field that must accompany the identifier in every access control log entry.

Associated clearance refers to a user's authorization level and is an attribute of the user account or access policy, not a required element that must be recorded within the access control log entry itself.
