Controlled-access describes a location, system, or resource where entry, use, or information retrieval is restricted to authorized individuals or entities. This often involves security measures like key cards, passwords, biometric scans, or security personnel. The primary goal is to prevent unauthorized access, protect valuable assets, maintain privacy, and ensure safety. Implementation varies widely from physical barriers at entrances to digital firewalls protecting sensitive data, depending on the nature and sensitivity of the resource being protected.
Controlled-access meaning with examples
- The hospital implemented controlled-access to its intensive care unit, requiring staff to use keycards and visitors to register with security.
