There are several security methods to choose from, depending on user’s needs and the
capabilities of user’s wireless machines.
WEP open
and
WEP shared
—WEP is an encryption scheme that is used to protect
user’s wireless data communications. WEP uses a combination of 64-bit keys or
128-bit keys to provide access control to user’s network and encryption security for
every data transmission. To decode a data transmission, each wireless client on the
network must use an identical 64-bit or 128-bit key. WEP is an older wireless
encryption method that is not as hard to break as the more-recent WPA.
802.1x
— In 802.1x (also known as RADIUS), a separate machine called an
authentication server receives a user ID and password. It grants or denies access
based on whether the ID and password match any entries in its account list. User
can optionally enable WEP encryption with this option. Because it requires a
separate machine acting as the authentication server, 802.1x is most often used
in business environments.
WPA
— WPA is a more recent encryption method that addresses many of the
weaknesses in WEP. Any client capable of WPA encryption should use it instead
of WEP.
WPA (PSK)
— This is WPA encryption combined with a pre-shared key (PSK), which
is a text string known only to the gateway and authorized wireless clients. The
