In which scenario would you use Network Access Control (NAC)?

Using Network Access Control (NAC) is pivotal in managing the security posture of a network by evaluating devices attempting to gain access. The primary function of NAC is to enforce security policies that ensure only compliant and trusted devices can connect to the network.

In the scenario where devices are evaluated based on their status, NAC can assess whether a device meets certain criteria, such as updated antivirus software, the latest operating system patches, and adherence to compliance regulations. Depending on the assessment, NAC can either grant full access, limited access, or deny access altogether. This targeted approach helps in mitigating risks associated with allowing potentially insecure devices into a network, thereby enhancing overall cybersecurity.

The context surrounding this option emphasizes the importance of proactive measures in network security management, particularly in environments with diverse device types and constant changes in threat landscapes. Implementing NAC strengthens the organization’s defense mechanisms by making access control contingent upon device security status, which is crucial for maintaining the integrity and confidentiality of the corporate network.
