Wireless security is the prevention of unauthorized access or damage to computers using wireless networks.
However, wireless networking is prone to some security issues.
Hacking has also become much easier and more accessible with easy-to-use Windows- or Linux-based tools being made available on the web at no charge.
Some organizations that have no wireless access points installed do not feel that they need to address wireless security concerns.
There were relatively few dangers when wireless technology was first introduced.
Hackers had not yet had time to latch on to the new technology, and wireless networks were not commonly found in the work place.
Since most 21st-century laptop PCs have wireless networking built in (see Intel "Centrino" technology), they don't need a third-party adapter such as a PCMCIA Card or USB dongle.
