An intrusion can be defined as any practice or act that attempt to crack the integrity, confidentiality or availability of a resource. This may consist of a deliberate unauthorized attempt to access the information, manipulate the data, or make a system unreliable or unusable. With the expansion of computer networks at an alarming rate during the past decade, security has become one of the serious issues for computer systems. As a result of this, Intrusion Detection Systems (IDS), which can effectively detect intrusion accesses, have gained attention.
