Defense Infrastructure: Improvements in DOD Reporting and Cybersecurity Implementation Needed to Enhance Utility Resilience Planning

Continuity of operations at DOD installations is vital to supporting the department s missions, and the disruption of utility services such as electricity and potable water, among others can threaten this support. House Report 113-446 included a provision that GAO review DOD s and the military services actions to ensure mission capability in the event of disruptions to utility services. This report addresses (1) whether threats and hazards have caused utility disruptions on DOD installations and, if so, what impacts they have had; (2) the extent to which DOD s collection and reporting on utility disruptions is comprehensive and accurate; and (3) the extent to which DOD has taken actions and developed and implemented guidance to mitigate risks to operations at its installations in the event of utility disruption. For this review, GAO evaluated DOD guidance and policies, interviewed appropriate officials, and visited or contacted 20 installations within and outside the continental United States, selected based on criteria to include those experiencing multiple disruptions, disruptions of more than one type of utility, and each military service. GAO recommends that DOD work with the services to clarify utility disruption reporting guidance, improve data validation steps, and address challenges to addressing cybersecurity ICS guidance. DOD concurred or partially concurred with all but one recommendation and disagreed with some of GAO s analysis. GAO believes the recommendations and analysis are valid as discussed in the report.
