Network Security

Network security refers to the protection of information and resources from loss, corruption, and improper use. Are wireless networks secure? Among businesses considering the implementation of a wireless system, this is a common and very important question. To answer this question, you must consider the functionality a wireless network performs.

A wireless network provides a bit pipe, consisting of a medium, synchronization, and error control that supports the flow of data bits from one point to another. The functionality of a wireless network corresponds to the lowest levels of the network architecture and does not include other functions, such as end-to-end connection establishment or login services that higher layers satisfy. Therefore, the only security issues relevant to wireless networks are those dealing with these lower architectural layers, such as data encryption.
