1. The wireless network has eased the process of expanding the existing networks. The Service Set Identifier (SSID) is the main information of the wireless network. Exposing the SSID cause possibility that the wireless network to be hacked. One of the countermeasures for this issue is by hiding the SSID from being exposed to the public. However, this technique is not fully effective. a. Explain how SSID hiding can increase the wireless network security (2 Marks) b. Explain the reason of SSID hiding or disabling technique is not entirely securing the wireless network? (4 Marks) C. IEEE 802.11b offers security services for its users. Briefly discuss TWO (2) security services available. (4 Marks) 2. Wireless network is unguided media which requires security solution to harden the communication. a. Define the source of keystream in Wired Equivalent Privacy (WEP). (2 marks) b. Discuss the differences between WEP and WPA2 in term of: a. Encryption technique b. Key distribution technique (4 Marks) c. Elaborate TWO (2) security services provided by WEP. (2 marks) d. Discuss the improvement made from WPA to WEP service from the perspective of key derivation and distribution perspective
