Wireless Intrusion Prevention System (WIPS)

5 minutes 5 Questions

A Wireless Intrusion Prevention System (WIPS) is a network security solution that monitors wireless network traffic and protects it from potential threats. It helps to identify unauthorized access points, rogue devices, and other potential security threats while ensuring that wireless networks operate efficiently. WIPS also detects and mitigates attacks such as Denial of Service (DoS), cracking attempts, and unauthorized attempts to access the wireless network. By continuously monitoring the network for suspicious activities, WIPS ensures that businesses can maintain secure and efficient wireless connectivity without sacrificing data security or network performance.

Guide on Wireless Intrusion Prevention System (WIPS)

Wireless Intrusion Prevention System (WIPS) is an essential concept in the CompTIA Network+ course.

What is WIPS?
WIPS is a network security solution that monitors, detects and mitigates threats on a wireless network. It protects the network from unauthorized access, misuse, malfunction, modification, destruction, or improper disclosure.

Importance of WIPS:
WIPS is an important component of any wireless network because it provides protection against attacks that can compromise the network's security. It helps in maintaining the integrity and confidentiality of the network.

How it works:
WIPS works by monitoring the radio spectrum for the presence of unauthorized access points (rogue APs). Once an unauthorized access point is detected, WIPS can either automatically take action to mitigate the threat or alert the network administrator.

Exam Tips: Answering Questions on WIPS
- Understand the principles of how WIPS works. This includes its role in protecting the wireless network and its method of detecting and mitigating threats.
- Be able to identify the key features of WIPS, its advantages, and potential challenges.
- Practice with real-life scenarios where WIPS would be implemented to enhance network security.
- Keep updated with the latest threats to wireless security and how WIPS can help address them.

This knowledge will be essential not just for understanding the role of WIPS in maintaining network security, but also for successfully answering related exam questions.

Question 1

Your company has introduced a bring-your-own-device (BYOD) policy. What should be enabled on the WIPS to support this change?

Rogue access point containment False positive reduction SSID cloaking Automatic device classification

Correct Answer: Automatic device classification

The 'automatic device classification' functionality should be enabled on the Wireless Intrusion Prevention System (WIPS) when your company introduces a bring-your-own-device (BYOD) policy. With this feature, the WIPS can correctly identify and classify each device that attempts to connect to the network, allow trusted devices, and restrict unknown or unauthorized devices. This is crucial in an environment where employees use their personal devices that can vary greatly in terms of makes, models, and operating systems. The other answers are not as applicable. 'SSID cloaking' is security through obscurity but it does not provide solid defense. 'Rogue access point containment' is a feature useful for managing unauthorized access points but does not specifically support a BYOD environment. 'False positive reduction' is important for overall WIPS efficiency, but it does not directly relate to handling BYOD policies.

Question 2

A retail business manager suspects a nearby competitor is conducting deauthentication attacks on their Wi-Fi network. Which WIPS feature can efficiently protect the network?

Rogue access point detection Deauthentication attack prevention Disabling traffic encryption Man-in-the-middle attack prevention

Correct Answer: Deauthentication attack prevention

Deauthentication attack prevention is specifically designed to detect and prevent attempts to disconnect devices from the Wi-Fi network. Disabling traffic encryption reduces security. Man-in-the-middle attack prevention does not address deauthentication attacks. Rogue access point detection helps protect against unauthorized access points, but not deauthentication attacks. Adjusting WIPS sensor sensitivity and enabling BYOD support are unrelated.

Question 3

In a healthcare environment, which WIPS feature can help prevent unauthorized access to patient information?

Geolocation features Reducing scanning frequency Rogue access point detection Disabling encryption

Correct Answer: Rogue access point detection

Rogue access point detection helps to identify unauthorized access attempts that may be used for data theft. Disabling encryption and enabling guest network access would reduce security. Reducing scanning frequency might allow unauthorized devices to go undetected. Geolocation features are used in conjunction with rogue access point detection to help locate these devices. MAC address filtering is a less comprehensive method compared to rogue access point detection.
