Legacy and Deprecated Trusted Internet Connections (TIC) Guidance

Revision Date

To keep pace with technological innovation and emerging cybersecurity trends, CISA continues to produce and update the core guidance through collaboration with agencies and vendors to maintain relevancy. This section houses a repository of draft and deprecated versions of the TIC 3.0 guidance for comparative purposes.

Note: The Security Capabilities Handbook below is now known as the Security Capabilities Catalog.

Prior to the release of OMB M-19-26 and the TIC 3.0 guidance in 2019, the security guidance for the legacy version of TIC (2017) was captured in the TIC Reference Architecture 2.2 (pdf, 3.02MB).
