Single Intruder Single Terminal (SIST) : Intrusion are launched by a single intruder from a single terminal device or its logical equivalent.
Single Intruder Multiple Terminal ( SIMT) : Intruder uses multiple windows on a computer to carry out or more intrusion. Alternatively intruder might use multiple windows to establish several connections to the same target , hoping to hide the intrusive activity by distributing the activity over several windows, each having a separate session to target computer
Multiple Intruder Multiple Terminal ( MIMT) : Multiple intruders participate in one or more intrusion simultaneously.
Stress Test : Intensity: The intensity checks if the IDS affected by sessions in which a lot of activity is generated very quickly, and therefore the IDS information source logs a lot of activity in short time.
“Stress Scripts” that simulates such a session should be created.
Script should simulate several user sessions.
Scripts logs all the activity after the intrusion and then logs out the user session.
Such script is normally combine form of Basic detection tests scripts.
The scripts should be run once.
Stress test can be repeated by several times , each time with different number of stress scripts running.
