Explanation:
Network Access Control (NAC) means controlling access to an environment through strict adherence to and implementation of security policies.
The goals of NAC are to prevent/reduce zero-day attacks, enforce security policy throughout the network, and use identities to perform access control.
Network access control lets IT departments determine which users and devices have authorized permissions, adding another level of security to the network and its data.
