Which term is used to describe a NAC category when enforcing access policies on devices attempting to connect to the network?

• A. Network Access Control (NAC)
• B. Intrusion Prevention System (IPS)
• C. Wireless IDS (WIDS)
• D. Secure Shell (SSH)

Answer: (A)

Network Access Control is the mechanism that enforces access policies as devices try to connect to the network. It checks the device’s posture and policy compliance (like antivirus status, OS version, or updates) and then decides the appropriate level of access—full access, restricted/quarantined access, or denial. This is exactly the concept described by describing the NAC category used for enforcing access when devices attempt to connect. The other options don’t fit because IPS is about detecting or preventing intrusions, WIDS focuses on wireless network monitoring, and SSH is a secure remote login protocol.
