WLAN discovery software such as NetStumbler, Kismet, or MacStumbler can be used to detect rogue access points if the victim is using IEEE 802 frequency bands. However, if the victim is using non-IEEE 802.11 frequency bands or unpopular modulations, these tools might not detect rogue access. NetStumbler, kismet, or MacStumbler also gives the authorization status of an access point. A Rogue access point (AP) is set up by the attackers in an Enterprise's network. The attacker captures packets in the existing wireless LAN (WLAN) and finds the SSID and security keys (by cracking). Then the attacker sets up his own AP using the same SSID and security keys. The network clients unknowingly use this AP and the attacker captures their usernames and passwords. This can help the attacker to intrude the security and have access to the Enterprise data. Answer: A, C are incorrect. The WLAN software such as NetStumbler, Kismet, or MacStumbler can search rogue access points even when the victim is using data encryption. However, these tools cannot determine the rogue access point even when it is attached to a wired network.
