Access control and intrusion detection is a unified system that allows users to monitor and control physical access to certain areas. This form of protection can extend to physical properties and into cybersecurity. Despite access control and intrusion detection being two separate hardware and software components, together they provide effective security measures.

Access control is responsible for restricting and granting access to specific people into particular areas. The goal of such software is to minimize unauthorized access to places, assets, and systems. This is where access control and intrusion detection in cybersecurity comes into play.

Intrusion detection relies heavily on identification and authorization. This means that users can only access restricted areas or devices through proper identification and level clearance. For this reason, we often see the software being guided by regulations and legal requirements.
