Critical Infrastructure Protection: CISA Should Assess the Effectiveness of Its Actions to Support the Communications Sector, Report to Congressional Addressees [open pdf - 2MB]
From the Highlights: "The Communications Sector, one of 16 critical infrastructure sectors, is vital to the United States. Its incapacitation or destruction could have a debilitating impact on the safety and security of our nation. The private sector owns and operates the majority of communications infrastructure, including broadcast, cable, satellite, wireless, and wireline systems and networks. DHS's CISA [Cybersecurity and Infrastructure Security Agency] is the lead federal agency responsible for supporting the security and resilience of the sector. GAO [Government Accountability Office] examined (1) the security threats CISA has identified to the sector, (2) how CISA supports the sector, and (3) the extent to which CISA has assessed its support and emergency preparedness for the sector. GAO reviewed DHS reports, plans, and risk assessments on the sector and interviewed CISA officials and private sector stakeholders to identify and evaluate CISA's actions to support the security and resilience of the Communications Sector. [...] GAO is making three recommendations to CISA, including that CISA assess the effectiveness of its support to the Communications Sector, and revise its 'Communications Sector-Specific Plan.' The Department of Homeland Security concurred with the recommendations. The Department of Commerce and the Federal Communications Commission did not provide comments on the draft report."
