Enlisted Expeditionary Warfare Specialist (EXW) Practice Test

What is a security measure taken to prevent single-person access to COMSEC keying material and cryptographic maintenance manuals?

1. Surveillance Cameras

2. Two Person Integrated

3. COC watch

4. Two Person Integrity

The correct answer is: Two Person Integrity

The correct answer is "Two Person Integrity" because this security measure ensures that critical operations involving COMSEC (Communications Security) keying material and cryptographic maintenance manuals are conducted with at least two authorized individuals present. This system of checks and balances is designed to reduce the risk of unauthorized access or misuse of sensitive information by requiring collaboration and oversight. When implementing Two Person Integrity, the inherent idea is that one person alone cannot access or handle sensitive materials, thus minimizing the possibility of an insider threat or accidental compromise. This principle is particularly crucial in the context of cryptographic security, where the stakes of maintaining confidentiality and integrity are extraordinarily high. Other options, while related to security, do not achieve the same level of prevention against single-person access in the context of COMSEC. Surveillance cameras might monitor activity but do not actively restrict access. COC watch refers to a command operation center watch structure, which is not specifically aimed at preventing individual access to sensitive materials. Two Person Integrated is not a recognized term in security protocols, making it less relevant in this context.
