Use encryptionEncryption is the number one security measure, but many wireless access  points (WAPs) don't have encryption enabled by default. Although most  WAPs support the Wired Equivalent Privacy (WEP) protocol, it's not  enabled by default. WEP has a number of security flaws, and a  knowledgeable hacker can crack it, but it's better than no encryption at  all. Be sure to set the WEP authentication method for "shared key"  rather than "open system". The latter does not encrypt the data; it only  authenticates the client. Change the WEP key frequently and use 128-bit  WEP rather than 40-bit.2. Use strong encryptionBecause of WEP's weaknesses, you should use the Wi-Fi Protected Access  (WPA) protocol instead of WEP if possible. To use WPA, your WAP must  support it (you may be able to add support to an older WAP with a  firmware upgrade); your wireless network access cards (NICs) must  support it (again, a firmware update may be necessary); and your  wireless client software must support it. Windows XP Service Pack 2  installs the WPA client. SP1 machines can be updated to support WPA by  installing the Windows WPA client with the Wireless.  Another  encryption option is to use IPsec, if your wireless router supports it.3. Change the default administrative  passwordMost manufacturers use the same default administrative password for all  their wireless access points (or at least, all those of a particular  model). Those default passwords are common knowledge among hackers, who  can use them to change your WAP settings. The first thing you should do  when you set up a WAP is change the default password to a strong  password (eight characters or more in length, using a combination of  alpha and numeric characters, not using words that are in the  dictionary).</blockquote>
