Which device detects attempts to cause a denial of service on a wireless network?

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

Answer: (A)

Wireless DoS attacks disrupt connectivity by targeting the radio spectrum, so the detector must monitor airwave activity for unusual patterns and attack signatures. A Wireless Intrusion Detection System specializes in this by continuously watching wireless traffic for signs of abuse—such as repeated deauthentication frames or abnormal beacon activity—and it raises alerts when it detects such activity. That focus on the wireless medium makes it the best fit for identifying attempts to deny service on a wireless network. An Intrusion Prevention System can detect and block threats, but it’s not specifically dedicated to wireless airspace analysis. Network Access Control manages which devices are allowed onto the network, rather than detecting DoS attempts. Secure Shell is a protocol for secure remote access and has no role in detecting wireless DoS events.
