Security Term

Network Access Control (NAC)

A security approach that enforces policy-driven access to a network based on the identity and health of connecting devices.

What is Network Access Control (NAC)?

NAC solutions assess devices before they connect, checking antivirus status, patch level, and configuration compliance, and grant access only to compliant devices. Non-compliant devices may be quarantined or given limited access. NAC is essential for BYOD and IoT environments.

Understanding this concept is crucial for maintaining a robust security posture. In the context of modern cyber threats, network access control (nac) represents a significant area of focus for security professionals and organizations alike.
