What does the National Industrial Security Program Operating Manual state about individual actions on an information system?

The National Industrial Security Program Operating Manual emphasizes the necessity for actions on an information system to be auditable. This means that each individual action taken by users must be capable of being traced and reviewed, ensuring accountability and the ability to monitor activities for security compliance. Auditing plays a crucial role in identifying and mitigating risks, detecting unauthorized access or use, and maintaining the integrity of sensitive information. This requirement supports the overarching goals of information security by facilitating oversight and establishing a clear record of user interactions with the system, allowing for effective security assessments and improvements.

The other options, while relevant in certain contexts, do not capture the essence of this aspect of the manual. Documenting actions, restricting access solely to managers, or requiring annual reports may not necessarily address the immediate need for ongoing oversight through auditable practices. Instead, focusing on auditability ensures that all actions can be continuously monitored and assessed for security compliance.
