Access Control

Access control is a security mechanism that regulates who can enter or use a particular resource, system, or facility. It is commonly used in physical security, such as keypads, biometric scanners, RFID card readers, and smart locks, to restrict unauthorized access to buildings or restricted areas. In digital security, access control ensures that only authorized users can access sensitive data, networks, or IT systems through authentication methods like passwords, multi-factor authentication (MFA), and role-based permissions.
