Information Sharing and Awareness

Information sharing is essential to the protection of critical infrastructure and to furthering cybersecurity for the nation. As the lead federal department for the protection of critical infrastructure and the furthering of cybersecurity, the Cybersecurity and Infrastructure Agency (CISA) has developed and implemented numerous information sharing programs. Through these programs, CISA develops partnerships and shares substantive information with the private sector, which owns and operates the majority of the nation's critical infrastructure. 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.

Automated Indicator Sharing

Automated Indicator Sharing (AIS), a Cybersecurity and Infrastructure Security Agency (CISA) capability, enables the real-time exchange of machine-readable cyber threat indicators and defensive measures to help protect participants of the AIS community and ultimately reduce the prevalence of cyber attacks. The AIS community includes private sector entities; federal departments and agencies; state, local, tribal, and territorial governments; information sharing and analysis centers and information sharing and analysis organizations; and foreign partners and companies. AIS is offered at no cost to participants as part of CISA's mission to work with our public and private sector partners to identify and help mitigate cyber threats through information sharing and provide technical assistance, upon request, that helps prevent, detect, and respond to incidents.

The AIS ecosystem empowers participants to share cyber threat indicators and defensive measures, such as information about attempted adversary compromises as they are being observed, to help protect other participants of the AIS community and ultimately limit the adversary's use of an attack method. The more you share, the more everyone becomes informed, and the more we all prevent further damage from vicious cyber-attacks together!
