What are the two types of PDSs in COMSEC reporting?

• A. Critical and non-critical
• B. Reportable and non-reportable
• C. Incident and non-incident
• D. Active and inactive

Answer: (B)

The two types of PDSs, or Protected Distribution Systems, in COMSEC reporting are classified as reportable and non-reportable. This classification is essential for understanding how incidents or issues related to these systems should be communicated within the context of communication security.

Reportable PDSs are those where incidents must be formally reported to ensure that proper actions can be taken to maintain the integrity and security of the system. This could include scenarios where there is a breach, potential compromise, or any situation that may jeopardize the secure transmission of classified information.

Non-reportable PDSs, on the other hand, do not require formal reporting for incidents that occur. These situations may still be monitored or documented internally, but they do not necessitate the same level of immediate concern or formal action as reportable incidents do.

Understanding this distinction is crucial for personnel involved in communication security because it dictates the procedures they must follow in the event of a security issue, influencing how quickly and effectively issues are handled and the necessary documentation maintained for accountability and compliance purposes.
