Wireless Network Security Vs. Wireless Perimeter Security

Perimeter and network security come together.

Although wireless network security and wireless perimeter security sound similar, they differ in several ways. One protects digital valuables or information, while the other protects the physical valuables such as people, places and objects. As with most things electronic and computerized, the two often come together to work towards a common goal.

Identification

Wireless perimeter security can be identified through the use of wireless devices such as IP cameras, heat and motion detectors, electronic badges or keys, as well as a management system to oversee the operation. Perimeter security regulates physical access to a specific location. Wireless network security takes the form of software, which puts up digital hurdles and road-blocks to regulate access to computer networks and the services and data stored on them--through the use of user names, passwords and complicated algorithms.

History

In 1994, Olympus released its first digital camera, which allowed users to upload pictures by cellular telephone lines. Security technology then exploded into the wireless field, incorporating live video feeds, biometrics and more. In 1999, wireless network security developed out of the need to provide wireless networks some form of security--specifically, the same level of security users had with wired networks.

Features

Wireless perimeter security installation includes places traditionally considered intensive, such as on bricked or concrete walls. Battery-powered units automatically recharge using sunlight, eliminating the need for external power. Those created for the purpose of security often link to specialized software for remote observation and storage. Wireless network security management, monitoring and updates occur remotely, with a physical presence on-site considered optional.

Benefits

Wireless devices, whether intended or not, can work with wireless perimeter security, allowing for a large range of products and prices to cover every possible perimeter security need. As networked devices, they form a comprehensive package. Combined with WEP, WPA, WPA2 or another form of wireless network security, perimeter security functions safely and relatively free of intrusion.

Considerations

Although excellent when they work, wireless signals can get interrupted. Turning on a microwave in the vicinity of a wireless device can scatter the signal. When installing in commercial areas, consider metal studding, the type of fastener used, the wiring and lighting, and anything else that may cause signal degradation. Wireless network security is just as frail--passwords can be lost, routers damaged and upgrades compromised--resulting in an inaccessible or inoperable wireless network.
