Cyber threats to the nation’s critical infrastructure sectors are significant. As such, it is important that federal agencies and critical infrastructure owners and operators share cyber threat information. ONCD and CISA lead federal efforts to coordinate on national cyber policy and the security of critical infrastructure. This report examines, among other things, (1) how federal agencies and critical infrastructure owners and operators share cyber threat information and (2) challenges to cyber threat information sharing and the extent to which federal agencies have taken action to address them. GAO is recommending that: (1) ONCD identify outcome-oriented performance measures for the cyber threat information sharing initiatives included in the National Cybersecurity Strategy implementation plan, and (2) CISA assess whether the current mix of centralized and sector-specific sharing methods used by agencies is the optimal approach to addressing cyber threat sharing challenges.

US National Cyber Security Strategy and Programs Handbook - Strategic Information and Developments

"President Biden's March 2023 National Cybersecurity Strategy lays out a bold, affirmative vision for cyberspace. It outlines a path for achieving two significant shifts: the need for more capable actors in cyberspace to bear more of the responsibility for cybersecurity and the need to increase incentives to make more investments in long term-resilience. ... This is the first iteration of the Implementation Plan, which is a living document that will be updated annually. Initiatives will be added as the evolving cyber landscape demands and removed after completion. The Office of the National Cyber Director will coordinate this work and report to the President and to Congress on the status of implementation. The United States Government will only succeed in implementing the National Cybersecurity Strategy through close collaboration with the private sector; civil society; state, local, Tribal, and territorial governments; international partners; and Congress. Agencies will work with the interested stakeholders to implement the initiatives of this Plan and build new partnerships where possible. The Administration will continue to refine Implementation Plan initiatives based on stakeholder feedback and assessments of their effectiveness."--Introduction.
