Researchers Identify Principles to Reduce Noise in Network Intrusion Detection Systems in SOC

Researchers from Eindhoven University of Technology analyzed 290,000 unique rules and 30 million alerts to identify design principles for reducing noise in Network Intrusion Detection Systems. The study found that a small subset of high-noise rules was responsible for the majority of false alarms, and that a balanced approach to rule design is crucial for effective threat detection. By implementing these principles, Security Operations Centers can reduce unnecessary workload and improve overall effectiveness.
