What does NAC stand for in the context of network access management?

In the context of network access management, NAC stands for Network Access Control. This concept relates to the policies and technologies used to ensure that only authorized users and devices can access certain networks or resources. NAC systems monitor and control the access to the network based on various criteria, such as user authentication, device health, and security posture. This is crucial for maintaining security and compliance in any organization, as it helps prevent unauthorized access and potential security breaches by enforcing rules about who can connect to the network and under what conditions.

The other options do not accurately capture the meaning of NAC in this specific context. While Network Authentication Code, Network Allocation Control, and Network Activity Checker might relate to other aspects of networking or security, they do not represent the comprehensive set of strategies and technologies encapsulated by Network Access Control.
