Optimizing Resource Monitoring with NodeBeacon: Anomaly Detection for SOC Efficiency

As a CISO overseeing SOC operations, unusual resource spikes can signal everything from DDoS to crypto-mining malware, yet traditional polling methods add complexity. NodeBeacon simplifies this with direct, polling-free monitoring of CPU, memory, disk, and network metrics, reporting anomalies to SIEM via syslog.

Features include real-time tracking, baseline deviation alerts, and time-over-threshold monitoring, all without SNMP or WMI dependencies.

Business advantages encompass performance visibility for capacity planning, security intelligence on compromises, and operational efficiency in distributed environments.

Threat hunting benefits include using resource anomalies as hunt triggers—analysts can correlate high CPU with process lists to hunt for hidden miners or malware. By trending disk usage, teams can detect data staging for exfiltration, while network index spikes help hunt for beaconing C2. Integrating metrics with logs allows for hypothesis testing, like simulating resource-intensive attacks to validate detections.
