Monitoring Activity
One of the best tools to use to maintain your wireless infrastructure
security is not any tool, but actual human intervention. The best way to
defend your network infrastructure from attack is to have an actual person
review the access logs and access attempts into your WLAN. If it
appears that someone is gaining access to network resources at off hours
or is attempting to break a password, you will be able to determine this
in a relatively short period of time.
Once you can determine if someone is attempting to gain access to
your systems, you can use techniques to triangulate the signal of the
person attempting to break into your network. For example, you can
trace the signal back to an attacker sitting in his car right outside your
building, and the police can make an arrest.
There are even law enforcement agencies who can take the uncorrupted
access logs from your access point and use that information as a
vehicle for prosecuting would-be attackers on your system. The reason I
say “uncorrupted” is because logs can be rewritten or modified by
intruders so that the information is inconclusive and cannot be used
against someone for prosecution. This is why early detection is the most
important element in making certain that your wireless infrastructure
remains secure and private.
