A centralized SIEM solution is not currently deployed for this application. Logging and monitoring are managed through AWS CloudWatch, which provides centralized log aggregation, monitoring, metrics, and alerting. Logs are retained securely and can be analyzed for performance issues and potential security events. AWS-native security services are also integrated to support proactive detection and response. While this is not a traditional enterprise SIEM, the solution provides centralized visibility, monitoring, and alerting within the AWS environment.
