What is the purpose of a security log?

The purpose of a security log is to track activities, incidents, and observations during shifts. This ensures that all significant events, whether they are routine activities or unusual occurrences, are documented in a systematic manner. By maintaining a thorough log, security personnel create a historical record that can provide insights into patterns of behavior, assist in investigations, and be instrumental in reviewing security protocols. The detailed nature of a security log enhances situational awareness and accountability, enabling security teams to make informed decisions and respond effectively to incidents.

The other options do not accurately capture the fundamental purpose of a security log. Recording personal opinions about incidents lacks objectivity and utility, while documenting shifts without detailing incidents fails to provide valuable information for assessing security operations. Using a security log solely as a backup for missing records undermines its primary function of creating a real-time, accurate account of activities and conditions.
