What is a requirement for all combinations used in a special access program facility?

• A. They must be easily memorable
• B. They must be the same throughout the facility
• C. They must be different for each door or container
• D. They mainly should include numbers only

Answer: (C)

In a special access program facility, one key requirement for combinations is that they must be different for each door or container. This is crucial for maintaining security. Using distinct combinations for different access points enhances the overall security architecture by minimizing the risk of unauthorized access. If all doors or containers had the same combination, it would create a significant vulnerability, as gaining access to one area could potentially compromise others.

Furthermore, having unique combinations allows for more controlled and monitored access, making it easier to ascertain which particular area was accessed and by whom, should a security event occur. This approach also aligns with best practices in security management, emphasizing the importance of compartmentalization and limited access to sensitive information or areas within the facility.

In contrast, other options suggest mechanisms that could either reduce security or complicate the compliance with security protocols. For example, easily memorable combinations may lead to easier unauthorized access, while having the same combination throughout the facility compromises the integrity of compartmentalized security. The idea that combinations should primarily include numbers only may not apply, as a combination can and often does include letters and symbols for added complexity and security.
