description: The Cybersecurity and Infrastructure Security Agency (CISA) is the United States federal civilian cybersecurity
  agency, part of the Department of Homeland Security. CISA reduces cybersecurity and physical security risk for the nation,
  coordinates federal civilian cyber defense, and partners with state, local, tribal, and territorial governments and the
  private sector. CISA publishes a number of public, unauthenticated machine-readable feeds, including the Known Exploited
  Vulnerabilities (KEV) catalog (mandatorily remediated by federal civilian agencies under Binding Operational Directive 22-01),
  Cybersecurity Advisories, and Common Security Advisory Framework (CSAF) advisories. CISA also operates an Automated Indicator
  Sharing (AIS) TAXII 2.1 server that delivers STIX cyber threat indicators to vetted partners under a Terms of Use and Interconnection
  Agreement.

  name: CISA Automated Indicator Sharing (AIS) TAXII Server
  description: CISA's Automated Indicator Sharing (AIS) program uses a TAXII 2.1 server to deliver STIX-formatted cyber threat
    indicators (CTI) and defensive measures (DM) to vetted partners. AIS includes AIS PUBLIC, FEDGOV, and CISCP feed communities.
    Connection requires a static IP, a Terms of Use, and an Interconnection Agreement; commercial data aggregators also redistribute
    AIS content to subscribers.
