Mac OS X WiFi Scanner for Snow Leopard

WiFi Scanner is a free 802.11 wireless scanner and connection manager for Mac OS X 10.6 Snow Leopard or late. This will detect access points and clients in ad-hoc mode if the SSID is being broadcasted. It can be used for wireless site surveys, wireless discovery, and to connect to wifi networks. The tool reports signal strength in dBm and shows access point BSSID/MAC addresses.

Rogue Wireless Access Point Scanner

Rogue Wireless Access Point Scanner – Online rogue wireless acces point scanner scans for wireless devices and then outputs a list of MAC addresses that belong to the wireless device that is plugged into the network.

WLAN Book BridgeChecker

WLAN Book BridgeChecker – BridgeChecker is a windows utility that can automatically disable/enable wireless interfaces. Whenever your computer is connected to an Ethernet port and the link state is good, the utility can automatically turns off the IEEE 802.11 wireless network interface. This conserves IP address allocation, reduces security risks, resolves dual interface routing issues, and prolongs battery life.

Getting the Most Out of Wireless LAN Tools

Tools you need to use to design and maintain a secure and highly-reliable wireless network:

1. Wireless Network Design Tools – The days of randomly placing access points and sensors are long gone. Predictive modeling to quickly understand RF behavior of environment is critical to helping design a network with proper coverage and capacity.
2. Wireless Network Site Survey Tools – Manual site surveys are always a good idea to help validate designs.
3. Wireless Network Security Tools – Encryption is just one piece, a complete wireless LAN security solution requires proper authentication and intrusion detection.
4. Wireless Network Hacking Tools – Its important to think the the “bad guys” and test a network as often as possible.
5. Wireless Network Analysis Tools – Proper network protocol analysis is easy with the right tools. It is best to have tools for analyzing live network data and from a capture file on disk.
6. Wireless Network Reporting Tools – Fraud = poor record keeping. Keep track of traffic, users, events to better understand the health and security of a wireless network.
