What Are Wi-Fi software tools?

The increasing use of the notebook computer and other wireless devices has promoted the use of Wi-Fi technology, which employs IEEE 802.11 or 802.11a technologies to provide secure connections. This is made possible by a wide array of software tools known as Wi-Fi software tools. These tools play different roles such as the ones outlined below:

  1. Denial of Service (or DoS) attacks against wireless systems which prevent the user from accessing or using his network connection.
  2. Wireless network encryption cracking of the transmitted data.
  3. Wireless network discovery for finding out which wireless networks are available
  4. Monitoring of dictionary and brutal attack force against the network, which is an attempt to gain the PIN for the network through various means.
  5. Wireless network traffic analysis which aid by graphically showing what kind of traffic is coming in and out of your network.
  6. Wi-Fi software tools are not heterogeneous, and are available for various platforms such as Windows, UNIX and Mac OS as well as for multiple platforms. The software systems for Windows include the following:

    KNSGEM II

    This program takes survey logs emanating from NetStumbler, WiFiHopper and Kismet and works with Google Earth to provide graphical representation of coverage maps in 3D.

    NetStumbler.

    This tool makes it possible to detect Wireless Local Area Networks (WLANS) using radio technologies such as IEEE 802.11b, 802.11a or 802.11q. Among other things, it ensures that your network’s settings are just as the way you intend them to be, as well as locating unauthorized access points on the network.

    Stumbverter.

    This is an application which allows the importation of Network Stumbler’s files into Microsoft’s MapPoint 2004. The Wireless Application Protocols (WAPs) which are logged -in will be represented by small, colorful icons depending on the Wired Equivalent Privacy (WEP) mode and strength of the signal.

    Lucent/Orinoco Registry Encryption/Decryption.

    This application is responsible for keeping WEP keys in the registry in an encrypted form. The application is useful, as it can encrypt the WEP keys into some value associated with the registry, or vice-versa.

    Wi-Fi Hopper.

    This is a Windows network discovery and connection client, and as such it takes part in network discovery, connection parameter settings and site surveys. There are filters that can allow you to choose what kind of details you want displayed, as well as what kind of settings you wish to be tested.

    Wireless software tools for UNIX

    Aircrack-ng.

    This has replaced its predecessor called Aircrack which, however, although out of development, is still functional. This software tool, like its predecessor, is a WEP and WPA-PSK key cracking utility.

    AirSnort.

    This is a wireless software tool whose main purpose ids to crack encryption keys on 802.11b networks. It works by monitoring the transmission and working out the encryption keys when enough packets have been accumulated.

    Wi-Fi Software tools for Mac OS:

    Kismet.

    Kismet is a network detector, sniffer and network intrusion detention system all rolled into one. It can work with any wireless card that supports raw monitoring mode. Networks on 802.11b, 802.11a and 802.11q are vulnerable to being sniffed out by Kismet.

    MacStumbler.

    This is a software tool that is mainly designed to locate access points while on the move, or to find out about any network problems.
