Wireless Security – Defining Keywords and Assessing the Threats

Wireless networks can offer convenience but could become a security nightmare if not used appropriately. In the future, advanced security measures might be applied to wireless networks to make a certain network more secure; however, this is not yet the case. Security of a LAN is often dictated by the physical properties of the medium it uses for communication, the methods used to transmit the data, the protocols that control the security of the transmitted data, and the policies that a certain LAN enforces to ensure authorized use. Wireless LANs use airwaves to transmit data, and are considered inherently insecure because the data transmitted are not physically bound like their counterpart, the wired LAN. To secure a wireless LAN, both operational and data security must be enforced. The security issues of wireless LANs are similar to those of the wired LAN.
