An Access Control System is a security solution that manages who is allowed to enter or exit specific areas of a facility. These systems can use a variety of authentication methods including:
- Keycards
- PIN codes
- Biometric identifiers (fingerprints, facial recognition)
- Mobile credentials
- RFID/NFC devices
The system records entry and exit data, providing a detailed audit trail of employee movement, which is especially useful for HR and security departments.
Types of Access Control Systems
1. Discretionary Access Control (DAC)
- The business owner or manager decides who gets access.
- Suitable for smaller organizations with simple needs.
2. Mandatory Access Control (MAC)
- Permissions are defined by system administrators based on levels of security clearance.
- Used in high-security environments (e.g., military or data centers).
3. Role-Based Access Control (RBAC)
- Access is based on an employee’s role within the organization.
- Efficient for larger businesses with multiple departments.
