| Prior to deploying any live wireless equipment in your enterprise, we recommend that you create a lab and test everything. Similarly, a wireless security expert will need a test lab of her own for research and development. A wireless test lab is completely different from your ordinary computer lab. Your wireless lab cannot be confined to a specific space. It needs to be mobile, just like your users will be. When testing for access point placement in your environment, there are several factors you need to consider. These factors are as follows:
Testing for coverage areas and deciding on placement locations can be a bit difficult, as it is difficult to bolt an access point to the ceiling and then constantly move it. Fortunately, we have come up with a better solution. Take a cart similar to those found in libraries and mount a telescoping pole to one of the sides. At the top of the pole, attach a flat piece of wood or plastic (not metal) that is big enough to hold the access point like a "ceiling," perpendicular to the ground. Offset the wood so that the access point can hang down without hitting the cart. Next, attach the access point upside down to the wood or plastic piece on the top of the pole. By raising the pole with the access point on top, you will place the access point at ceiling height and still be able to move it by pushing the cart. On the cart should be a battery connected to an inverter, giving you a power source in which to plug the access point. By walking the floor with a laptop or PDA, you are able to test connectivity to the access point. We also recommended that you test not only the area you are attempting to cover, but also the surrounding areas. This will enable you to map wireless coverage that inadvertently "bleeds" beyond your perimeter. The best type of lab configuration is one that will closely resemble your production environment. In addition, the lab should be flexible enough to allow you to test new products, and allow for future network expansions. And remember—test everything!

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 ...
2. 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...
3. 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...
4. 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...
5. 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...
6. 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 ...
7. WLAN Broadcasting ~ MiniStumbler ~ a wireless network scanner
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 MiniStumbler MiniStumbler is a basic one-file program that simply needs to be downloaded, unzipped, and placed in the My Documents sha...
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...
9. Concerns for Mobile Enterprises
Although it is one thing for organizations to keep up with the latest industry trends, making it happen in everyday life is a totally different story. The following are some of the key concerns of enterprises that are contemplating a mobile e-commerce strategy: Security: Wireless networks are very easy to break into and difficult to monitor. Your enterprise assets must be protected. Management: Effective management of the components that make up a mobile enterprise, all the way from servers to the ...
10. Wireless Attacks ~ Client to Client Hacking
Clients exist on both wireless and wired networks. A client can range from anything such as a Network Attached Storage (NAS) device, to a printer, or even a server. In a typical ad-hoc network, there are no servers or printers—just other individuals' computers. Because the majority of consumer operating systems are Microsoft based, and since the majority of users do not know to how to secure their computers, there is plenty of room to play here. For example, an attacker can strike at a laptop that uses a wireless ...
