That's why we need to calibrate IDS. Initially IDS need to run in test mode
and monitor the alert it produces and justify which one is true or false
positive so you can disable the alert. False positive alarm WILL raise no
matter how secure your network is because of web applications or
non-standard communication protocols. If you want to see what I mean, setup
a standard snort gateway and open www.bharian.com.my within your client and
snort will warn you that bharian is trying to hijack your connection, and
this is an example of false positive alert.

Post Script: IDS is not plug and play system
