Protecting Access
One method that can help you protect your wireless resources is to
deploy mandatory mutual authentication that requires that traffic not
be sent until the user is authenticated to the server. Unfortunately,
most implementations to not offer authentication options, so support
will come from the evolution of access points with this capability.
Some of the early 802.11 implementations are not able to use the persession
keys derived to encrypt your data transmission. These implementations
only encrypt data using multicast/broadcast default keys.
These types of implementations are vulnerable to a number of WEP
attacks, especially if the default keys are not automatically changed frequently
and do not follow any given pattern for such changes. The
administrator of your deployment needs to use automated methods to
change the default key to create secure management mechanisms that
keep your wireless network protected against these types of attacks.
As hackers become more and more savvy, and acquire a wealth of
automated hacking tools, your network security must evolve to deal with
these constant threats.
