KisMAC is a free stumbler application for MacOS X, that puts your card into the monitor mode. Unlike most other applications for OS X it has the ability to run completely invisible and send no probe requests. Unlike console-based Kismet, KisMAC offers a pretty GUI and was around before Kismet was ported to OS X. These are few things among many that KisMAC can do: reveals cloaked SSIDs, reveals logged in Clients (incl. MAC Addresses), mapping and GPS support, visualization of network coverage, PCAP im- and export, support for 802.11b & g, different attacks against encrypted networks, deauthentication attacks, Apple Script compatible (in newest SVN version).

Netstumbler is a free windows wireless sniffer. It is the most popular windows tool for finding open wireless access points (”wardriving”) using the 802.11b, 802.11a and 802.11g WLAN standards. It is also useful in verifying network configurations, finding locations with poor coverage in one’s WLAN, detecting causes of wireless interference, detecting unauthorized (”rogue”) access points, aiming directional antennas for long-haul WLAN links.

Netscreen series integrated devices incorporating a firewall, IPSec VPN capabilities, and denial of service mitigation, with Unified Threat Management (UTM) security features including Stateful firewall, IPS, Antivirus, Anti-Spyware, Anti-Phishing, Anti-Adware, Anti-Spam, and Web Filtering to protect the network from attack. I’ve installed and manage a lot of Netscreen firewalls. They’re excellent UTM device but if you’re looking for a cheaper option, then Sonicwall also can do the job.

Kismet is a very powerful and popular wireless network detector, sniffer, and intrusion detection system. Kismet will work with any wireless card which supports raw monitoring (rfmon) mode, and can sniff 802.11b, 802.11a, and 802.11g traffic. Kismet identifies networks by passively collecting packets and detecting standard named networks, detecting (and given time, decloaking) hidden networks, and infering the presence of nonbeaconing networks via data traffic. It can automatically detect network IP blocks by sniffing TCP, UDP, ARP, and DHCP packets, log traffic in Wireshark/TCPDump compatible format, and even plot detected networks and estimated ranges on downloaded maps.

Airsnort is a wireless LAN (WLAN) tool which cracks WEP encryption keys. AirSnort passively monitors wireless transmissions and automatically computes the encryption key when enough packets have been gathered. AirSnort runs under Windows or Linux, and requires that your wireless nic be capable of rf monitor mode, and that it pass monitor mode packets up via the PF_PACKET interface.
