These systems might use various forms of authentication such as key cards, biometric scans, or personal identification numbers (PINs). The primary purpose of access control systems is to protect physical, human, and information assets by controlling the movement of personnel and restricting unauthorized access. They also allow for the audit of people's movement in and out of the controlled areas, helping to identify potential security breaches or incidents.

Importance: Access Control Systems are critical for maintaining the security integrity of any organization. They help to restrict unauthorized access and manage permissions for resources within a physical or online environment. These systems ensure that only authorized individuals can access sensitive data or areas.
What is an Access Control System? An Access Control System is a set of system level protocols that control who or what is allowed to access certain resources in a physical or virtual environment. It can be used to manage logical access (to networks, systems and data) and physical access (to buildings, rooms and data centers).
How it Works: It works based on four fundamental principles: identification, authentication, authorization and accountability. Initially, a user is identified, then their authenticity is verified. Once authentication is successful, the user is authorized to access certain resources depending on their access level. Finally, all activities are logged for accountability.
