Which type of physical security measure involves controlling access points to a building?

Access Control Systems are crucial for managing who can enter or exit a building. They implement various mechanisms to ensure that only authorized individuals gain entry, effectively protecting the premises from unauthorized access. These systems can include key card readers, biometric scanners, and password-protected entry points, providing a reliable means of controlling access.

By integrating technology with policy, Access Control Systems enhance physical security by allowing administrators to grant or revoke access as needed, track movements within the building, and maintain a record of entries and exits. This capability is vital for preventing security breaches and ensuring the safety of personnel and assets within the facility.

In contrast, while Intrusion Detection Systems focus on identifying unauthorized intrusions, Surveillance Cameras serve to monitor activities for security purposes but do not inherently control access. Physical Barriers, like fences or gates, can help restrict entry physically but do not manage access permissions in the way Access Control Systems do. Thus, the primary function of controlling access points aligns closely with the functions of Access Control Systems.
