DHS/ALL/PIA-060 Application Authentication System (AppAuth)

The Application Authentication System (AppAuth) is a Department of Homeland Security (DHS) enterprise system developed and operated by the DHS Headquarters Information Sharing and Services Office (IS2O). AppAuth is a DHS single sign-on enterprise authentication service, which provides a uniform authentication service based on Microsoft’s Active Directory services. DHS is updating this Privacy Impact Assessment (PIA) because AppAuth will now share personally identifiable information (PII) outside of the Department and within a Government specific public-cloud instance (Azure).
