# MIDASEC07-BP02 Implement SIEM systems
<a name="midasec07-bp02"></a>

 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

+  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.
