System and method of dynamically weighted analysis for intrusion decison-making

An intrusion detection system, comprising:

• an analysis module that receives first configuration information from an intrusion detection skin, wherein the first configuration information identifies a set of one or more analysis approaches to be executed and a weight to apply to each of the one or more analysis approaches, and executes the set of one or more analysis approaches against event information generated by one or more computing elements in a computer environment;
• a filtering mechanism that determines a score based on one or more policies;
• and
• a score interpreter that determines whether the event information represents an intrusion based on the score.

A computer program product for intrusion detection in a computer environment, the computer program product comprising:

• a computer usable medium having computer usable program code embodied therein;
• computer usable program code configured to receive first configuration information from an intrusion detection skin, wherein the first configuration information identifies a set of one or more analysis approaches to be executed and a weight to apply to each of the one or more analysis approaches;
• computer usable program code configured to execute the set of one or more analysis approaches against event information generated by one or more computing elements in the computer environment;
• computer usable program code configured to determine a score based on one or more policies;
• and
• computer usable program code configured to determine whether the event information represents an intrusion based on the score.
