Healthcare System Log Monitoring and Anomaly Detection

Create an advanced Bash monitoring script for healthcare IT infrastructure that continuously scans system logs, network traffic, and user access records. Implement real-time threat detection mechanisms that: 1) Parse log files using grep and awk, 2) Identify potential security breaches or unauthorized access attempts, 3) Generate immediate email/SMS alerts for critical events, 4) Create comprehensive security incident reports, 5) Automatically quarantine suspicious IP addresses. Include configurable sensitivity levels and integration with centralized security information and event management (SIEM) systems.
