Systems and methods are described for conducting work flows by an SIEM device to carry out a complex task automatically. According to one embodiment, an SIEM device may create a work flow that includes multiple security tasks that are performed by one or more security devices. When a security event is captured or the work flow is scheduled to be executed, the SIEM device starts the work flow by scheduling the security tasks defined in the work flow. The SIEM device then collects results of security tasks performed by the one or more security devices.
