While this book demonstrates all the security vulnerabilities of your
WLAN, it is clear that because there are so many advantages to using a
WLAN in your corporate environment, these devices will not disappear
any time soon from the IT landscape within your organization.
While you can never expect to provide 100 percent security for your
WLAN, you can take the simple precautions outlined in this book to look
for potential vulnerabilities, plug those holes, and prevent hackers from
corrupting your resources. If a hacker does break into your network,
keeping accurate logs is an excellent way of tracing that network activity
so that you can block any future attempts.
Above all, make certain you have good security professionals monitoring
your network logs and real-time network activity for any potential
problems. Hackers love to try to hack into your network late at night on
off hours, or during weekends when very few people are in your corporate
facilities. By examining the network logs, it is not only possible to
detect spikes in abnormal network usage activity, but you can look for
low-level hacking activity, where a hacker attempts to guess at your settings
a little each time so as not to trigger any possible alarms you
might have configured to detect items such as a distributed denial of
service attack on your systems.
Wireless LANs will undoubtedly improve greatly in terms of speed,
usability, and security as time goes on. Authentication and PKI mechanisms
are only the beginning of locking down your WLAN so that you
can control access to any of your networking resources.
For the most part, an ounce of prevention is all you need to prevent
damage to your wireless network before it starts. Keep an eye out for
suspicious activity and make certain you inform your users to stay vigilant
about who has access to your network and what rules you have in
place through your security policy so that only specified users have
access to selective resources. If you monitor your network and watch all
wireless connections, you can be certain that you can provide sufficient
security to provide a dedicated wireless network and stay problem free.
