Authorization is the process of granting or denying access to individuals based on their verified identity and assigned permissions. Access control systems use authorization rules defined by administrators to determine the level of access each user should have. User roles, access groups, or explicit access permissions are commonly used to control and enforce authorization rules.


Accountability is a crucial feature of access control systems, enabling organizations to track and monitor access activity. These systems maintain audit logs or event logs that record access attempts, successful or unsuccessful access, and other relevant events. Accountability helps in identifying any security breaches, determining patterns of suspicious activity, and ensuring compliance with security policies and regulations.

Benefits of Access Control Systems

Implementing an access control system provides numerous benefits for organizations and individuals alike.
