MIDASEC07-BP02 Implement SIEM systems
Aggregate and analyze logs from industrial and cloud systems using a security information and event management (SIEM) system to help detect and respond to threats efficiently.
Desired outcome: Centralized visibility across hybrid environments enables faster detection of coordinated threats or unusual activities.
Benefits of establishing this best practice: Improves threat correlation, reduces alert fatigue, and strengthens compliance with audit trails.
Level of risk exposed if this best practice is not established: High
Implementation guidance
Use Amazon Security Lake or integrate with third-party SIEM tools such as Splunk or IBM QRadar for advanced analytics and incident workflows.
Implementation steps
-
Set up Amazon Security Lake to collect and normalize logs from AWS and industrial sources.
-
Integrate with a SIEM system for event correlation and alerting.
-
Define detection rules and dashboards tailored to OT and ICS environments.
-
Automate incident response workflows with runbooks or SOAR integrations.
