014.01.64.4. How does Linux handle wireless network authentication and encryption, and what role does the wpa_supplicant daemon play in managing both authentication and encryption for a wireless network interface? Explain the importance of securing wireless networks and why Wired Equivalent Privacy (WEP) is discouraged.
This question evaluates the candidate's knowledge of wireless network security in Linux, focusing on authentication and encryption. It also tests their understanding of the significance of securing wireless networks and the reasons behind discouraging the use of WEP.
wpa_supplicant daemon handles wireless network authentication and encryption for the wireless network interface. This daemon handles both WPA2 and WPA3 (WiFi Protected Access) schemes of authentication, as well as nearly any kind of encryption technique used on wireless networks. It's important to secure wireless networks, as otherwise they are easily accessible which raises certain concerns regarding speed, network security. WEP is dicouraged as its not secure and isn't supported by many networks.
