INFO: What is Wireless Security
Wireless Security prevents unauthorized access to wireless networks. The wireless signal in a home is accessible outside the walls of the residence and if a malicious user uses the network for illegal activities, the owner and operator of the network can be held accountable.
There are two primary types of wireless security, WPA and WEP. Both security measures use security keys or encryption keys to protect the network.
WEP is compatible with almost all devices, but the security can be broken by an experienced hacker given time. WEP also uses a longer security key that is typically random letters and numbers.
WPA and WPA2 is slightly less compatible but is far more secure, also uses a shorter, easier to remember security key. Most wireless devices made in the last five years support WPA and WPA2.
