6 - Configuring Security

7. (802.11b/802.11a) Configure basic WEP 64/128/152 security. You can
configure up to four different WEP keys on the access point and most
wireless end devices, and then you specify which key is being used to
encrypt data. You should periodically change which WEP key these
devices use. For help, see Configuring WEP 64/128/152 Security on
page 162.
8. (802.11b/802.11a) Use an 802.1x security solution. 802.1x security
provides a framework to authenticate user traffic to a protected
802.11b or 802.11a network. Using 802.1x security provides secure
data transmission by enabling secure IAPP, enabling secure wireless
hops, and dynamically rotating the WEP keys. You configure the
access point as an authenticator.
For the authentication server, you can either use an external
RADIUS server or you can use a newer access points Embedded
Authentication Server (EAS).
For help, see Implementing an 802.1x Security Solution on
page 164.
