NAC - Network Access Control

Network Access Control (NAC) is a security solution that ensures only authorized and compliant devices are granted access to a network. NAC systems enforce security policies and assess the health status of devices seeking to connect to the network, allowing organizations to mitigate security risks and maintain a secure network environment.

The Security+ exam may cover the fundamental concepts of NAC, including its purpose, components, and the processes involved in assessing and controlling network access. Additionally, knowledge of NAC's role in endpoint security and network segmentation is important for the exam.
