Unplugged data can also be hack-proof data

By Maggie Biggs, InfoWorld |  Networking

Both types of spread spectrum enormously increase wireless network security, especially when combined with available encryption techniques.

Spread-spectrum technology requires users to have very specific knowledge to gain access to wireless network traffic, which decreases the possibility of unauthorized users or hackers gaining access to your systems. For instance, direct-sequence spread spectrum requires intruders to somehow acquire the chipping code for network entry, and frequency-hopping WLANs require acquisition of the hopping pattern. In both cases, intruders also need to acquire frequencies and modulation techniques as well as scrambling patterns to decode signals and gain full entry.

Although these encouraging attributes paint a bright picture for the growth of corporate WLANs, companies still need to keep a sharp eye on their networks' evolving security needs and act promptly when problems are suspected. Networking security advances are made daily, but intruders are simultaneously getting smarter, building tools to circumvent even the newest security methods.

This solemn warning is no more pressing for WLANs than for wired networks. When it comes to security, companies should feel as confident in wireless systems as they do in traditional LANs. When implemented well, WLANs can indeed be watertight, while of course also providing the conveniences that made them so appealing in the first place: greater mobility and freer, less tied-down working styles.
