Which system detects and prevents unauthorized wireless devices and rogue access points?

• A. Wireless IDS (WIDS)
• B. Wireless Intrusion Prevention System (WIPS)
• C. Network Intrusion Prevention System (NIPS)
• D. Intrusion Detection System (IDS)

Answer: (B)

In wireless security, the system that both detects rogue devices and access points and takes action to stop them is required. A wireless IDS monitors the radio spectrum, flags unauthorized devices and rogue APs, and logs alerts, but it doesn’t automatically block them. A wireless intrusion prevention system builds on that by not only detecting threats but also enforcing defenses in real time—things like deauthenticating rogue clients, isolating or blocking a rogue AP, and enforcing wireless security policies. General NIPS or IDS focus on wired or broader network traffic and may miss or be unable to effectively contain wireless-specific threats. Therefore, the solution that detects and prevents unauthorized wireless devices and rogue access points is a Wireless Intrusion Prevention System.
