Wireless Intrusion Prevention System (WIPS)

5 minutes 5 Questions

A Wireless Intrusion Prevention System (WIPS) is a security solution that monitors, detects, and neutralizes potential threats on a wireless network. WIPS uses a combination of sensors and software to continuously scan the wireless environment, identifying rogue access points, unauthorized devices,ā€¦

Question 1

Following a recent security audit, your company has discovered unauthorized access to its wireless network. Which WIPS feature can prevent rogue access point connections?

Correct Answer: Rogue access point containment

The best answer is 'Rogue access point containment'. This is a feature of Wireless Intrusion Prevention Systems (WIPS) that can prevent rogue access points from connecting to the wireless network. It does this by detecting rogue access points and actively preventing them from communicating with the network. The other answers are incorrect because they do not specifically address the prevention of rogue access point connections. 'False positive reduction' is about reducing incorrect alerts, not preventing access. 'Intrusion detection system' is a broader concept that includes detection but not necessarily prevention of access. 'SSID cloaking' is a method of hiding a network's name, not preventing rogue access points from connecting.

Question 2

A company recently installed a WIPS to protect their wireless network. Suddenly, employees are unable to connect to the network. What is the most likely cause?

Correct Answer: WIPS is accidentally blocking legitimate connections

WIPS, or a Wireless Intrusion Prevention System, is designed to monitor, detect, and defend against unauthorized wireless network access attempts. If suddenly after installation of WIPS employees are unable to connect to the network, the most likely cause is the WIPS accidentally blocking legitimate connections. This situation could be due to overzealous security settings or a misconfiguration. The other answers are not as likely. If the WIPS was not properly configured, it may not function at all or fail to provide adequate protection, but it would not typically prevent all connections. Similarly, if WIPS is detecting interference as false positives, then it may issue alerts or kick off unauthenticated devices, but it wouldn't disconnect all employees. Lastly, if the wireless access point was down, that would indeed prevent connection, but that's a separate issue from WIPS.

Question 3

A small business has recently deployed a new WIPS and is experiencing intermittent connection issues. Which WIPS feature should be adjusted to reduce false positives?

Correct Answer: Tuning the WIPS sensor sensitivity

Adjusting WIPS sensor sensitivity can help fine-tune the balance between detecting legitimate threats and reducing false positive alerts. Disabling WIPS or ignoring rogue access points would reduce security, disabling BYOD support is unrelated to WIPS sensitivity, MAC spoofing protection doesn't address false positives, and increasing WIPS scan frequency might increase alerts.
