Best Practices

1. Runtime Protection Strategy

Deploy as Java agent for comprehensive instrumentation
Implement defense in depth with multiple monitoring layers
Use behavioral analysis for zero-day threat detection

2. Performance Optimization

Use efficient data structures for real-time monitoring
Implement sampling for high-frequency events
Cache baseline calculations

3. Container Security

Leverage container runtime security features
Implement drift detection for immutable infrastructure
Use namespaces and cgroups for isolation

4. Incident Response

Implement automated response actions
Integrate with SIEM and SOAR platforms
Maintain audit trails for forensic analysis

5. Compliance and Governance

Implement regulatory compliance checks
Generate compliance reports automatically
Maintain security posture dashboards

This Titliel Aqua Runtime implementation provides comprehensive cloud-native runtime protection with advanced threat detection, behavioral analysis, and automated response capabilities for enterprise Java applications.
