Washington, DC -- OST and TSA are revising their regulations governing the protection of sensitive security information (SSI) to remove an unintended limitation on parties that have a need to know such information. Specifically, this rule removes the limiting words "aviation or maritime" from 49 CFR 15.11 and 49 CFR 1520.11 in order to clearly permit the sharing of vulnerability assessments and other documents properly designated as SSI with covered persons who meet the need to know requirements regardless of mode of transportation.
