H-ISAC is a trusted community of critical infrastructure owners and operators within the Health and Public Health sector (HPH). The community is primarily focused on sharing timely, actionable and relevant information with each other including intelligence on threats, incidents and vulnerabilities that can include data such as indicators of compromise, tactics, techniques and procedures (TTPs) of threat actors, advice and best practices, mitigation strategies and other valuable material. Sharing occurs both via machine to machine and human to human. H-ISAC also fosters the building of relationships and networking through a number of educational events in order to facilitate trust. Working groups and committees focus on topics and activities of importance to the sector and produce white papers for public sharing. Offerings such as Shared Services provide enhanced services to leverage the extensive H-ISAC community for the benefit of all.
