The Industrial Control Systems Joint Working Group (ICSJWG) has created a consolidated document; a sector independent roadmap. This Cross-Sector Roadmap was conceived and developed over the last two years by industry and government thought leaders that saw the need for a unifying Roadmap to secure control systems across all critical sectors. Version 3 of the consolidated roadmaps is available for download. The document aids entities in creating a cybersecurity plan that incorporates the unique environment of control systems. The document is an excellent addition to a utility’s cybersecurity reference library and is available here.
 

The Industrial Control Systems Joint Working Group (ICSJWG) was established by the Department of Homeland Security to facilitate information sharing and reduce the risk to the nation’s industrial control systems. The group meets regularly and has several active sub-groups. The ICSJWG provides a vehicle for communicating and partnering across all Critical Infrastructure and Key Resources Sectors (CIKR) between federal agencies and departments, as well as private asset owners/operators of industrial control systems.
