CWS Wireless Security & Troubleshooting Techniques

Question 1

Which protocol is used to secure wireless networks?

Accepted Answer

WPA2

Answer

WPA2 (Wi-Fi Protected Access II) is a robust security protocol widely used to secure wireless networks. It employs strong encryption algorithms, such as AES, and authentication methods to protect data transmitted over Wi-Fi from unauthorized access and eavesdropping. While WPA3 is newer, WPA2 remains a common and effective standard for securing most wireless networks.

Question 2

What is MAC address filtering?

Accepted Answer

Allowing only authorized device addresses

Answer

MAC address filtering is a network security method that allows a network administrator to control access to a wireless network by specifying which devices are permitted to connect. Only devices whose unique Media Access Control (MAC) addresses are on an approved list will be granted access. This adds a basic layer of security by restricting unauthorized devices from joining the network.

Question 3

What tool is used to analyze signal strength?

Accepted Answer

Wi-Fi analyzer

Answer

A Wi-Fi analyzer is a specialized tool, often available as a mobile app or desktop software, used to scan for wireless networks and display crucial information about them. Its primary function is to measure and visualize signal strength, identify channel congestion, and detect sources of interference. This data is invaluable for optimizing Wi-Fi network performance and troubleshooting connectivity issues.

Question 4

What can reduce signal interference in Wi-Fi?

Accepted Answer

Change Wi-Fi channel

Answer

Wi-Fi networks operate on specific channels, and if multiple networks or other electronic devices in the vicinity use the same channel, signal interference can occur. Changing your Wi-Fi router to a less congested channel can significantly reduce this interference. This improves signal quality, increases data transfer speeds, and provides a more stable wireless connection.

Question 5

Which is a common wireless security risk?

Accepted Answer

Open network with no encryption

Answer

An open wireless network with no encryption is a significant security risk because all data transmitted over it is completely unprotected. Anyone within range can easily intercept and read sensitive information, such as passwords, personal data, or financial details. This lack of security makes the network highly vulnerable to eavesdropping and unauthorized access.
