What does NAC stand for in network security?

NAC stands for Network Access Control in the context of network security. It is a security solution that enforces policies for accessing computer networks. NAC systems ensure that only authorized devices and users can connect to the network, which helps protect sensitive data and resources from unauthorized access and potential security threats.

Network Access Control functions by assessing the security posture of devices attempting to access the network before granting them permission. This can include checking for updated antivirus software, security patches, or compliance with organizational security policies. By utilizing NAC, organizations can better manage risks associated with endpoint connections and maintain a more secure network environment.

Other options represent different concepts and do not align with the established terminology in network security. For example, "Network Application Compliance" might suggest a focus on application-level security compliance, which is not a recognized acronym in network access management. "Network Analysis Center" refers to a facility or unit that focuses on analyzing network traffic and performance rather than controlling access. "Network Asset Codification" suggests a method of identifying and managing assets but is not related to access control in a security context.
