Information Sharing and Analysis Center
AbbreviationISAC

An Information Sharing and Analysis Center (ISAC) is an organization that provides a central resource for gathering information on cyber and related threats to critical infrastructure and providing two-way sharing of information between the private and public sectors.[1][2]

Sector ISACs began forming in 1999, subsequent to the May 22, 1998 signing of U.S. Presidential Decision Directive-63 (PDD-63), when "the federal government asked each critical infrastructure sector to establish sector-specific organizations to share information about threats and vulnerabilities."[3] Decision Directive-63 (PDD-63) was replaced by Homeland Security Presidential Directive 21 in 2013.
