| MiniStumbler is a very user-friendly wireless network scanner that listens for beacon signals coming from open and broadcasting WLANs. In addition, this program will provide a plethora of information that makes it very useful for both hackers and the security professionals. As you will see, MiniStumbler might be small, but it packs a load of power in its functionality. Installing MiniStumblerMiniStumbler is a basic one-file program that simply needs to be downloaded, unzipped, and placed in the My Documents shared folder that is used to pass files from host to palmtop. After the ministumbler.exe file is located on the iPAQ's file system, the program is ready to use. However, the requirements are very strict with regards to WNICs and drivers. Using MiniStumblerMiniStumber is just as easy to use as its big brother, NetStumbler. Assuming a properly working WNIC is installed, MiniStumbler will execute and inform the user that the program is sniffing by displaying the phrase NO AP; otherwise the phrase No wireless will be displayed. If you are in the presence of an access point, the status message will read 1 AP. In addition, if you have a GPS unit connected to the iPAQ, the program will display GPS On. Because the program executes in a running status, there is not much more to do other than search for wireless networks. The readout is straightforward, although it does require scrolling. However, most of the important information is available on the main screen. The first thing you will notice is a small colored circle with the MAC address of the access point or WNIC, the SSID, and a colored circle representing the signal strength. The following lists the colors and their meanings:
Other useful features of MiniStumbler include the following:
As you can see, this program is a powerful tool for any security auditor. Because this program is available on both laptop and Pocket PC-based computers, with basically the same functionality in each, the Stumbler suite is a necessity. The only disadvantage of this program is the limited WNIC support. MiniStumbler will only support two types of WNICs: the ORiNOCO WaveLAN and the Compaq WL110. Other cards might work, such as the Dell TrueMobile, but it might take some tweaking and research to accomplish this.

Despite the prevalence of standards committees in the wireless industry, there is no single unifying standard. It is important for enterprises to consider all the aspects involved in mobile support while contemplating a strategy for mobile e-commerce. Some of the key criteria in choosing a wireless network specification include: Average size of transfers Number of devices in the wireless network Others Range of transmission Secur...
2. Wireless Attacks ~ War Driving
When a surveillance attack is either impossible or too difficult, war driving is an effective alternative. In many situations, war driving follows and adds information to a prior surveillance attack. Conversely, the information obtained from random war driving often leads to a surveillance attack on a discovered location. The term war driving is borrowed from the 1980s phone hacking tactic known as war dialing. War dialing involves dialing all the phone numbers in a given sequence to search for modems. In fact, this method of ...
3. How To Get Photo Quality Prints
There are a variety of ways to get photo-quality prints from your digital images. You can make them yourself with a printer at home, or have a photo finisher do the work for you. Many camera stores offer photo finishing from digital images. Simply take in your memory card, order the prints, and pick them up the next day. This service is now available in most drugstore chains, too—instead of dropping off a roll of film while running your errands, you leave them your memory card instead. You can also order prints throu...
4. Wireless Privacy Protocols ~ WEP detailed
The Wired Equivalent Privacy protocol is incorporated as part of the IEEE 802.11b protocol. Actually, the standard only calls for 40-bit WEP, but almost all vendors offer up to 128-bit WEP. To secure data, WEP uses the RC4 algorithm to encrypt the packets of information as they are sent out from the access point or wireless network card. This is the same algorithm used in many other Internet applications that require security, such as Secure Sockets Layer (SSL). SSL is the most common protocol used by online stores to e...
5. Wireless Attacks ~ Rogue Access Points
Rogue access points are those connected to a network without planning or permission from the network administrator. For example, we know one administrator in Dallas who just did his first wireless security scan (war driving) on his eight-building office campus. To his surprise, he found over thirty access points. Worse, only four of them had authorization to be connected to the network. Needless to say, heads rolled. Rogue access points are becoming a major headache in the security industry. With the price of low-end ac...
6. Wireless Network Protocols ~ Advantages and Disadvantages of Bluetooth
There are various wireless communication protocols. These technologies range in scope from long distance WLANs to one-meter IrDA devices. Each of these technologies has its niche, as well as its attendant strengths and weaknesses. For example, WLANs enable the transmission of data up to several hundred feet, but often require manual configuration changes that are difficult to implement. On the other hand, IrDA permits a seamless connection between devices without the need for extra configuration. However, their usability is de...
7. Wireless Network Protocols ~ Understanding HomeRF and IrDA
About the same time WECA approved the 802.11 standard, several other types of wireless technologies were being introduced. Although a few have made a rather impressive niche in the Personal Area Network (PAN) market, the only other WLAN technology that came close to competing with 802.11 was HomeRF. Using the Shared Wireless Access Protocol (SWAP), HomeRF merges the 802.11 FHSS standard with the six voice channels based on Digital Enhanced Cordless Telecommunications (DECT). In other words, the home network included both ...
8. How To Present a Digital Slideshow
Slideshows are an age-old photographic tradition. Digital cameras make it easier than ever to present your images to many people at once. Most digicams have a "video out" capability that lets you connect your camera directly to a television for playback on a large screen. If your camera has this functionality, it most likely has a slideshow mode that allows you to choose images that are stored on the memory card and present them on the television in timed intervals. All you have to do is turn on the stereo for some ba...
