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.
