Digital Bond Inc. used PI infrastructure for detecting security threat to control system workstations. Under the contract from the Department of Energy, Digital Bond partnered with OSISoft to research for the best security practice for control system. PI infrastructure collects data from network, workstation, control system application and field devices. ACE module then correlates security threats with the collected data to detect security “meta events”. Digital Bond’s research result of using PI to add security intelligence to control systems will be available in summer 2008.
