Conclusion: Finding Security in an Unsecured World
Conclusion: Finding Security in an
Unsecured World
This chapter has focused on the concept of how a wireless network can
effectively provide the same level of security as that of a wired network.
However, the most important section of this chapter details all the ways
in which the wired equivalent privacy (WEP) can be circumvented
through several methods including:
IRL in real-life physical damage
Jamming and interference
Eavesdropping
Unauthorized access
By understanding these methods of attack, you can determine the
best manner in which you can prevent a hacker from accessing your system
and compromising the WEP of your wireless network. Using WEP
encryption enables your WLAN to resist the way in which encryption
keys are stolen. Effectively managing these keys maintains the wired
equivalent privacy of your WLAN so that you can use your network with
the confidence of maintaining a level of security analogous to that
offered by a wired LAN. 133
Physical barriers and protection mechanisms are the most important
means of making certain that hackers are unable to gain access to precious
network resources.
What equipment is vulnerable?
Access points/wireless routers
Laptop computers
Wireless PDAs
Wireless network interface cards
Network printers
Network file servers
Network fax servers
Effectively maintaining physical safeguards prevents hackers from
getting into these systems in person, and therefore makes it harder for
them to log in wirelessly. The idea is to protect wireless users as well as
the actual access points; only then can you be certain to manage all your
network resources effectively.
Finally, maintain a log of every activity on your WLAN. Keeping this
information protects you from hacking activity. Your best defense in
keeping your network secure is to make certain you can identify malicious
activity on your system. If you maintain a vigilant eye on your
resources, you can effectively protect your wireless network against
many possible intrusion attempts.
Following these guidelines will enable you to operate a secure wireless
network without fear of being hacked.
