The DOD 2015 Cyber Strategy reported that a cyber attack could present a significant risk to U.S. national security. House Report 114-102 included a provision that GAO assess DODs plans for providing support to civil authorities for a domestic cyber incident. This report assesses whether 1 the National Guard has developed and DOD has visibility over capabilities that could support civil authorities in a cyber incident and 2 DOD has conducted and participated in exercises to support civil authorities in cyber incidents and any challenges it faced. To conduct this review, GAO examined DOD and National Guard reports, policies, and guidance and interviewed officials about the National Guards capabilities in defense support to civil authorities. GAO also reviewed after-action reports and interviewed DOD officials about exercise planning.
