What Is Wireless Security
Network security in a wireless LAN environment is a unique challenge. Whereas wired networks send electrical signals or pulses through cables, wireless signals propagate through the air. Because of this, it is much easier to intercept wireless signals. This extra level of security complexity adds to the challenges network administrators already face with traditional wired networks.
There are a number of extremely serious risks and dangers if wireless networks are left open and exposed to the outside world. This article covers the types of attacks wireless networks encounter, preventive measures to reduce the chance of attack, guidelines administrators can follow to protect their company's wireless LAN, and an excellent supply of online resources for setting up a secure wireless network.
