Intrusion Detection Systems (IDS) have inherent limitations which lead to false positives and false negatives; the authors propose that combining signature and anomaly based IDSs should be examined. This paper contrasts signature and anomaly based IDSs, and critiques some proposals about hybrid IDSs with signature and heuristic capabilities, which is designed to offer superior pattern analysis and anomaly detection by reducing false positive rates and administrator intervention. In this paper, they address these two issues of accuracy and efficiency using conditional random fields and layered approach.
