Frequently Asked Questions
What is network access control?
NAC decides which users and devices may join a network and what they can reach. It checks identity and health before granting access, and can quarantine non-compliant devices.
How does 802.1X work?
A supplicant, such as a laptop, authenticates through a switch or access point to a RADIUS server using EAP. Only after success is the port or connection opened.
What is posture assessment?
Posture assessment checks a device's security state, like patches or antivirus, before allowing access. This advanced Codelivly room is free and shows how NAC enforces it.
