(1) The outside of any front and back cover, including a binder cover or folder, if the document has a front and back cover;
(2) Any title page; and
(3) Each page of the document.
(b) Protective marking. The protective marking is: SENSITIVE SECURITY INFORMATION.
(c) Distribution limitation statement. The distribution limitation statement is:
WARNING: This record contains Sensitive Security Information that is controlled under 49 CFR parts 15 and 1520.. No part of this record may be disclosed to persons without a “need to know”, as defined in 49 CFR parts 15 and 1520, except with the written permission of the Administrator of the Transportation Security Administration or the Secretary of Transportation. Unauthorized release may result in civil penalty or other action. For U.S. government agencies, public disclosure is governed by 5 U.S.C. 552 and 49 49 CFR parts 15 and 1520..
(d) Other types of records. In the case of non-paper records that contain SSI, including motion picture films, videotape recordings, audio recording, and electronic and magnetic records, a covered person must clearly and conspicuously mark the records with the protective marking and the distribution limitation statement such that the viewer or listener is reasonably likely to see or hear them when obtaining access to the contents of the record.
