The Department of Homeland Security (DHS) includes an amalgamation of organizations that work together to prevent and respond to terrorist attacks, natural disasters, and other threats. Such collaboration requires that components establish effective communication among external and internal partners during operations. DHS established an internal goal of developing interoperable radio communications and identified common channels, and its components invested about $430 million in equipment, infrastructure, and maintenance to meet communication requirements. We performed this audit to determine whether DHS’ oversight ensured achievement of Department-wide interoperable radio communications.
Consistent with CDC guidance, most Office of Inspector General employees are currently serving the American people remotely. We are determined to keep interruptions to our operations to a minimum, and we appreciate your patience during this time.
