Why Have an IDS?

There is a very important reason why you need an intrusion detection
system—it gives you an essential layer of security that you must have in
order to keep wireless hackers from gaining access to your network
without your knowledge.

In fact, even end-users are strongly urged to implement personal
intrusion detection systems into their wireless workstations because it
is an important layer of security. An administrator can view the logs
your IDS generates in order to track and prevent hackers from gaining
access to either the network or your laptop hard drive.

There are different types of intrusion detection systems:


Computer decision (the computer determines if the alert warrants an
e-mail alert to the administrator)

Real live people (an IDS center makes the determination if your computer
is being hacked—even if it is a slow hack over a period of days
or weeks)
