After how many working days must End of month destruction be reported?

The correct choice indicates that end-of-month destruction must be reported within a timeframe of five working days. This requirement is crucial for maintaining effective COMSEC (Communications Security) practices. Reporting within this period ensures that all necessary documentation and accountability measures are upheld, fostering a reliable record of destruction activities.

Timely reporting within five working days aids in ensuring compliance with established security protocols and procedures. It allows for prompt oversight and verification of destroyed materials, which is key in preventing unauthorized access to sensitive information. This timeframe strikes a balance between being timely enough to ensure proper reporting and allowing personnel enough time to accurately document and report the destruction events.

In contrast, longer periods would pose risks in terms of security and accountability, as delays could lead to lapses in maintaining a comprehensive and up-to-date record of destroyed material. Hence, the five-day reporting window is established to support the integrity of comms security operations while ensuring effective management and compliance.
