The Transportation Security Administration (TSA) has issued a Sources Sought notice seeking a Two-Factor Authentication (TFA) solution that can conclusively authenticate an individual–such as Transportation Security Officers, other TSA employees and stakeholders–who, from an external resource such as a home computer or public kiosk, sees access to Microsoft Outlook Web Access and Microsoft Office Sharepoint Services portals that physically reside within the TSA infrastructure. These applications are currently limited to use by internal employees and contractors, as well as external stakeholders that connect on systems that have an established direct or virtual private network connection to the TSA network. The TFA solution shall provide multifactor identification and authentication consisting of a user identity, password and one additional authentication factor. The initial scope of the effort is limited to the stand up of the GFE to be located at TSA headquarters, 6th floor data center, and the associated licenses for 5,000 users for six months. Longer term, the effort will support 50,000 users for three years. Sol. No. HSTS03-10-R-CIO042. Respond by Dec. 11. Contact: Michael Villano, [email protected].
