Preventing Network Intrusion Attempts

There are two ways in which to prevent network intrusion attempts on

your WLAN (Figure 18.5).

1. Use an automated intrusion detection system that uses a form of

fuzzy logic to detect and report any possible hacking type of activity.

These types of systems are mostly automated and use a preprogrammed

set of attack signatures to identify hackers attempting to

gain access to your wired or wireless network. If a hacker does try to

gain unauthorized access, a computer program monitoring network

activity will notify the administrator if any suspicious activity

occurs. A good example of this type of intrusion detection system can

be found at intrusion.com.

2. Use of a manual intrusion detection system that is staffed by actual

people. A company will put a special device inside your internal network

that securely transmits network logs and activity to the managed

service company, using actual people to look for suspicious

activity and inform your administrators if you are experiencing

hacking activity. A good example of a company that actually uses

experienced security professionals to monitor your systems for suspicious
