Which security measure must be applied to COMSEC material from receipt to destruction?

• A. Delegated Authority Security
• B. Two-Person Integrity (TPI)
• C. Continuous Monitoring
• D. Restricted Access Protocol

Answer: (B)

The correct choice emphasizes the importance of Two-Person Integrity (TPI) as a crucial security measure in handling COMSEC material throughout its lifecycle—from receipt to destruction. TPI ensures that at least two authorized individuals are present when handling sensitive materials, which significantly reduces the risk of unauthorized access or misuse. This practice is particularly important in COMSEC environments, where the integrity of information is paramount.

TPI provides a layered approach to security by requiring mutual oversight and verification, thereby preventing any single person from having exclusive control or oversight of sensitive data or materials. This shared responsibility not only helps to safeguard against malicious actions but also minimizes the risk of accidental mishandling or errors.

Other options may pertain to aspects of security but do not specifically address the comprehensive, ongoing requirement for dual oversight and accountability that TPI provides in the context of COMSEC material. For instance, Continuous Monitoring might refer to ongoing surveillance of security systems, while Restricted Access Protocols might limit access rights, but neither encompasses the specific dual-person requirement integral to TPI when managing sensitive COMSEC material.
