Access control is a security system that controls who is allowed to enter or exit a building, facility, or restricted area. It can be used to ensure that only authorized individuals have access to sensitive areas, as well as to track and monitor the movements of people within a facility.
There are several types of access control systems, including:
- Physical access control: This involves the use of physical barriers, such as doors, gates, and turnstiles, to control access to a location. Physical access control systems may also include the use of identification cards, key fobs, or biometric scanners to verify a person’s identity.
- Network access control: This type of access control system controls access to a computer network or other electronic system. It may use passwords, security certificates, or other forms of authentication to verify a person’s identity and grant them access to the system.
- Software-based access control: This involves the use of software to control access to a system or network. This type of access control system may use login credentials or other forms of authentication to verify a person’s identity and grant them access to the system.
An access control service is a service that provides access control systems and related support to businesses and organizations. This may include the installation and maintenance of physical access control systems, as well as the management and support of software-based access control systems.
