Access control

Access control refers to the practice of managing and restricting access to certain resources or areas within a system or physical space. It ensures that only authorized individuals are able to access specific information, data, or locations.

Access control systems typically involve the use of authentication methods such as passwords, biometrics, or security tokens to verify the identity of users before granting them access. These systems also often include authorization mechanisms that determine the level of access granted to each individual based on their role or permissions.

Access control is a crucial aspect of security measures in both digital and physical environments. In digital environments, access control is used to protect sensitive data and prevent unauthorized users from accessing confidential information. This can help prevent data breaches, identity theft, and other cyber threats. Meanwhile, in physical environments, access control is used to secure buildings, rooms, and other areas from unauthorized entry. This can help prevent theft, vandalism, and other security risks.
