Today the number of Laptops, PDA's and Mobile Phones that use Wireless Communication Technologies is increasing in every minute. PDA's give you the opportunity to access to the internet, check your email and much more. Mobile phones too, they help you to send Multi-Media Messages (MMS, for example photo or MP3 files) to other people with cell phones or individual email addresses. You can also use General Packet Radio Service (GPRS) that is probably provided by your mobile phone network's operator to access to the internet. You can simply use Laptop, PDA or Cell Phones to establish connection to each other via Bluetooth. These devices all give you the ability to "enter a network mobile which has many benefits for you. However, wireless networking has many security issues. Crackers have found wireless networks relatively easy to break into, and even use wireless technology to crack into non-wireless networks."1
"An increasing number of government agencies, businesses, and home users are using, or considering using, wireless technologies in their environments. Agencies should be aware of the security risks associated with wireless technologies. Agencies need to develop strategies that will mitigate risks as they integrate wireless technologies into their computing environments. ...
We will also point to some of the ways crackers use to enter wireless networks and how they can easily bring down even a whole none wireless network via that.
An Overview of Wireless Technology
No physical connection is established between the devices in a wireless network. No cable or wire to joint two devices to each other or one device to a network. All devices connect through radio frequencies to transmit the data. Wireless technology may involve complicated systems such as Wireless Local Area Networks known as WLAN. It may also include simple devices that do not have a storage system such as wireless headphones and microphones. Devices with Infra-Red technology are also involved such as a wireless mouse or a remote controller.
Wireless Networks help implementing a mechanism to transmit data between devices and also inside the devices. These networks are categorized into three main groups. Wireless Wide Area Networks or WWAN for example GSM (Global System for Mobile Communications), Wireless Local Area Networks or WLAN and Wireless Private Area Networks known as WPAN technology for example Bluetooth.
Mainly, the devices that use wireless technology are the devices that can be carried easily from one place to another such as Laptop computers, Personal Digital Assistants (PDA's) and Cell Phones. "Many laptop computers have wireless cards pre-installed for the buyer." 4
"PDAs are data organizers that are small enough to fit into a shirt pocket or a purse. PDAs offer applications such as office productivity, database applications, address books, schedulers, and to-do lists, and they allow users to synchronize data between two PDAs and between a PDA and a personal computer. Newer versions allow users to download their
