Healthcare System Log Aggregation and Threat Detection

Design a complex Bash-based log aggregation and security monitoring script for healthcare IT infrastructure. The script must collect and analyze logs from multiple sources (EHR systems, network devices, authentication servers) using advanced grep/awk parsing, detect potential security anomalies, and generate comprehensive threat reports. Implement machine learning-inspired pattern recognition to identify unusual access attempts, create automatic IP blacklisting, and generate detailed forensic reports compatible with HIPAA security incident documentation requirements.
