secret-key information. The access point provides two schemes for authenticating users: 802.1x EAP
and Kerberos.
Encryption applies a specific algorithm to alter its appearance and prevent unauthorized reading.
Decryption applies the algorithm in reverse to restore the data to its original form. Sender and
receiver must employ the same encryption/decryption method to interoperate.
Wired Equivalent Privacy (WEP) is available in two encryption modes: 40 bit (also called WEP 64) and
104 bit (also called WEP 128). The 104-bit encryption mode provides a longer algorithm (better
security) that takes longer to decode (hack) than the 40-bit encryption mode.
Each WLAN (16 WLANs available in total to an access point regardless of the model) can have a
separate security policy. However, more than one WLAN can use the same security policy. Therefore,
to avoid confusion, do not name security policies the same name as WLANs. Once security policies
have been created, they are selectable within the
existing default security policy does not satisfy the data protection requirements of a specific WLAN,
a new security policy (using the authentication and encryption schemes discussed above) can be
created.
