Patrick, My suggestion is to use counters for several types of entities. Each IDS event will increment some counters with a given quantity, according to its severity. Then you use thresholds based on the pontuation of the entities in a given time interval. A entity that rises above the threshould triggers an alert and the events that caused the above-average pontuation are showed to the analyst for further investigation. Some good entities can be: hosts, networks, applications, users, protocols. You can improve the system by monitoring traffic with netflows and generating events for abnormal traffic, also based on thresholds.

Hi There I am doing a project of applying data mining techniques to Intrusion Detection systems. I am also interested in DECISION SUPPORT SYSTEM (Note that this is decision SUPPORT system, not decision MAKING. So it does not make decision but SUPPORT the decision making process.). So I decide to have DECISION SUPPORT SYSTEM as a section of my project. The problem is that I dont know how to LINK Intrusion Detection to DECISION SUPPORT SYSTEM. I thought: IDS can detect possible THREATS and this helps Network Admin to make DECISION about the security level, or DO corrective ACTIONS. Can you give me some thoughts of HOW TO LINK/RELATE IDS to DECISION SUPPORT SYSTEM? In the other words, how IDS can be considered as a DECISION SUPPORT SYSTEM and are there any products relating to this topic in real world? Thanks Have a nice day Patrick Tran ------------------------------------------------------------------------ Test Your IDS Is your IDS deployed correctly?
