COMSEC TS material requires which level of integrity and control?

• A. Two-person integrity; in constant view of one another
• B. One-person integrity; single lock
• C. Three-person integrity; three locks
• D. Two-person integrity; in constant view of one another; two locks with different combinations and no one person having knowledge of both combinations

Answer: (D)

COMSEC TS material is protected by dual custody and dual control to prevent any single person from gaining access. The idea is that two qualified individuals must be present and able to observe each other while handling the material, providing constant oversight and accountability. Access is secured with two locks and different combinations, and crucially, no one person knows both combinations. That way, both custodians must cooperate to access the material, which protects against both theft and covert misuse. Other approaches that rely on a single person or do not enforce dual-control and separation of knowledge would create a single point of failure and reduce protection.
