Knowledge-Based and Behavior-Based IDS:

Knowledge-Based IDS: Knowledge-Based IDS, also known as signature based, are reliant on a database of known attack signatures. Knowledge-based systems look closely at data and try to match it to a signature pattern in the signature database. If an incident matches a signature, the IDS registers that an attack has happened or is happening and responds with an alert, alarm or modification to firewall configuration.

The main weakness of a knowledge-based IDS is that its effectiveness is based on known attack methods. Upgraded or altered versions of known attacks are often undetected by the IDS. Therefore, a knowledge-based IDS is only as effective as its signature database so the database must be kept updated.
