Frequently asked questions

Why use security information and event management (SIEM) for energy automation systems?

A Security Information and Event Management (SIEM) system conducts the following tasks in a scalable manner:

  • The SIEM centrally collects security-relevant events and alerts from all system components across the different OT sites (such as substations) and continually stores them in their chronological order
  • The SIEM is backed by site-local persistence and protection of the event information in substation syslog servers
  • All information is evaluated in the SIEM to reduce noise in the information, correlate them and detect abnormal behavior of/in the systems
  • If the SIEM detects an attack or an anomaly, an alarm message is issued and the operator is immediately notified
  • The SIEM can be used for a forensic analysis and reporting after a cyber incident
  • It is the basis for a comprehensive incident response practice that helps prevent or minimize the damage to critical power systems operations from cyber incidents
