ISACs by IIT
Since 9/11, IIT has operated dedicated Information Sharing and Analysis Centers (ISACs). Homeland Security Presidential Directive 7 created private sector ISACs to better protect key Critical Infrastructure. On a 24/7 basis, multiple IIT-operated ISACs provide cyber and physical threat monitoring, analysis, sector subject matter expertise, and incident response support to their respective key sector stakeholders. This experience gives IIT unique expertise performing all-hazard threat monitoring and analysis on a national scale.
