What is the primary purpose of security policies enforced by NAC?

The primary purpose of security policies enforced by Network Access Control (NAC) is to control who and what can access the network. NAC solutions work by establishing policies that help to manage and enforce the conditions under which devices can connect to the network. This includes verifying the identity of users and devices, ensuring compliance with security policies, and granting or restricting access based on those evaluations.

By controlling access, NAC enhances security by ensuring that only authorized users and compliant devices are allowed to connect to the network, thus reducing the risk of unauthorized access, potential breaches, and other security threats. This management of access is a fundamental component of any organization's cybersecurity strategy, as it protects sensitive information and resources from malicious actors.
