Misuse Detection ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object]
Misuse Detection Methods & System AutiGUARD Case Based reasoning IDES,NIDX,P-BEST,ISOA Expert System IDIOT Colored Petri Automata STAT family(STAT,USTAT,NSTAT,NetSTAT) State Transition Analysis RUSSEL,P-BEST Rule-based Languages System Method
Anomaly Detection ,[object Object],[object Object]
Anomaly Detection Methods & System JAM, MADAM ID Data mining approaches ,[object Object],[object Object],[object Object],[object Object],[object Object],IDES, NIDES, EMERALD Statistical method System Method
Anomaly Detection Disadvantages ,[object Object],[object Object],[object Object]
Misuse Detection vs. Anomaly Detection High false-alarm and limited by training data. Is able to detect unknown attacks based on audit Anomaly Detection Cannot detect novel or unknown attacks Accurately and generate much fewer false alarm Misuse Detection Disadvantage Advantage
The Frame for Intrusion Detection
