threat-detection

To detect port scans in network traffic, apply these explicit thresholds: port entropy must exceed 6.0, the SYN-only ratio must be greater than 0.7, and unique ports must exceed 100. This multi-condition approach accurately identifies malicious scanning patterns.

Identify network beaconing behavior in pcap data by calculating the inter-arrival time (IAT) coefficient of variation (CV). Flag connections as malicious beaconing when the IAT CV is strictly less than 0.5, indicating regular interval communications.

Yes, you can apply these exact threat detection thresholds to real-time enterprise network monitoring and incident response. The rule-based thresholds for port scans, DoS, and beaconing are designed for both real-time analysis and pcap processing.

Using exact numerical thresholds for intrusion detection provides transparent, rule-based identification of malicious patterns without model training overhead. This approach ensures deterministic results for port scans, DoS, and beaconing across enterprise networks.

Fixed thresholds for network threat detection may not adapt to evolving attack vectors or benign traffic anomalies that mimic malicious patterns. You should regularly validate these explicit rules against your specific enterprise network baseline to minimize false positives.
