Explanation

Network Admission Control (NAC) is a security technique that verifies the identity and compliance of the endpoints (devices or users) that attempt to access a network. NAC supports validation of the endpoint's security posture prior to allowing the session to go into an authorized state, which means that NAC checks whether the endpoint meets the predefined security policies and requirements, such as having the latest patches, antivirus software, firewall settings, or encryption standards, before granting network access. NAC can also enforce remediation actions, such as updating, quarantining, or blocking the endpoint, if it does not comply with the security policies and requirements. NAC can prevent unauthorized, infected, or vulnerable endpoints from compromising the network security and performance.
