Explanation
Closed network, SSID spoofing, and MAC address filtering are techniques that can be used to secure wireless networks. In the closed network technique, the wireless access point (WAP) does not broadcast its Service Set Identifier (SSID). Users are required to know the SSID to ensure whether or not the wireless network exists. In the SSID spoofing technique, a software generates numerous WAP packets that advertise bogus SSIDs. When hackers scan for a wireless network, they receive the bogus SSIDs that cannot be differentiated from a valid SSID. Most WAPs support MAC address filtering that limits the clients, so that the WAP communicates only with valid media access control (MAC) addresses. Answer option B is incorrect. In IP spoofing, a user modifies packet headers using someone else's IP address to hide his identity. However, IP spoofing cannot be used while surfing the Internet, chatting online etc. This is because forging the source IP address causes the responses to be misdirected.
