Description: Physical access control is a security measure that limits access to facilities and resources. Its primary goal is to protect physical assets, such as buildings, server rooms, and critical equipment, from unauthorized access. This type of control is implemented through various technologies and methods, which may include locks, access cards, biometric systems, and video surveillance. The main features of physical access control include user authentication, authorization for access to specific areas, and auditing of access events. The relevance of this security measure lies in its ability to prevent theft, vandalism, and other incidents that can compromise the integrity of an organization’s assets. In various environments, physical access control is complemented by security policies that define who can access which areas and at what times, thus ensuring a secure and controlled environment. Additionally, in the context of cybersecurity, physical access control is considered a first line of defense, as it protects critical systems and data from external and internal threats.
