NAC policy enforcement

NAC (Network Access Control) policy enforcement is a security process that ensures only authorized devices and users gain access to a network. When someone tries to connect, NAC checks their device's security status—like current updates or compliance with security policies—and verifies their identity. If everything aligns with the organization's rules, access is granted; if not, connection is restricted or denied. This helps maintain a secure network environment by continuously verifying that devices meet security standards before allowing network access.
