Information sharing is essential to furthering cybersecurity for the nation. Isolating cyber attacks and preventing them in the future requires the coordination of many groups and organizations. By rapidly sharing critical information about attacks and vulnerabilities, the scope and magnitude of cyber events can be greatly decreased. With the right plans, processes, and connections in place, information sharing can be seamless step of incident response procedures and a first defense against wide-spread cyber attacks.
As the lead federal department for the protection of critical infrastructure and the furthering of cybersecurity, CISA has developed and implemented numerous information sharing programs. Through these programs, CISA develops partnerships and shares substantive information with the private sector. CISA also shares information with state, local, tribal, and territorial governments and with international partners, as cybersecurity threat actors are not constrained by geographic boundaries.
