Who was responsible for enforcing access control policies before electronic access control systems?

Before the advent of electronic access control systems, the primary responsibility for enforcing access control policies rested with security officers. These individuals played a critical role in managing physical security measures, which included monitoring access points, verifying the identities of individuals entering secured areas, and ensuring that only authorized personnel could access sensitive locations.

Security officers were tasked with the implementation of access control measures, such as overseeing the use of keys, locks, and security badges. They would often conduct manual checks and patrols to maintain security and prevent unauthorized access. This human oversight was vital in maintaining the integrity of access control policies, especially in environments where sensitive information or valuable assets were involved.

The other options, such as employees, automated systems, or the IT department, either did not carry the same level of authority in enforcing access control or were not primarily responsible for physical security before the shift to electronic systems.
