The Department of Homeland Security (DHS) Trusted Identity Exchange (TIE) is a privacy-enhancing DHS Enterprise Service that enables and manages the digital flow of identity, credential, and access-management data for DHS employees and contractors. It does so by establishing connections to various internal authoritative data sources and provides a secure, digital interface to other internal DHS consuming applications. A consuming application is any DHS system that requires some form of identity, credential, and access-management data in order to grant logical or physical access to a DHS protected resource. DHS is updating and replacing the original Privacy Impact Assessment (PIA) because TIE’s expanded usage across DHS has created additional requirements.
