A network encrypted with WPA/WPA2 is more secure than a network
encrypted with WEP, because WPA/WPA2 uses dynamic key encryption.
To protect the information as it passes over the airwaves, you should enable
the highest level of encryption supported by your network equipment.
WEP is an older encryption standard and may be the only option available
on some older devices that do not support WPA.
See Security Settings for Wireless Networks, page 56.
• Keep wireless routers, access points, or gateways away from exterior walls
and windows.
• Turn wireless routers, access points, or gateways off when they are not
being used (for example, at night or during vacations).
• Use strong passphrases that are at least eight characters in length.
Combine letters and numbers to avoid using standard words that can be
found in the dictionary.
See Password Rules for Password Complexity, page 156.
General Network Security Guidelines
Wireless network security is useless if the underlying network is not secure. Cisco
recommends that you take the following precautions:
• Password protect all computers on the network and individually password
protect sensitive files.
• Change passwords on a regular basis.
• Install anti-virus software and personal firewall software.
• Disable file sharing (peer-to-peer). Some applications may open file sharing
without your consent and/or knowledge.
