A paper may be marked as “For Official Use Only” (FOUO) only when it contains information that falls under one or more of the nine exemptions outlined in the excerpt above.
Do not use FOUO as a device to restrict your thesis; instead, use a restricted distribution statement for this purpose, as FOUO is a control statement that is independent from the distribution statement on the cover page of your thesis. In other words, FOUO is separate from, and in addition to, the distribution statement, if needed.
If your paper contains FOUO information, portion mark with "(FOUO)" only the applicable paragraphs, headings, images, and captions. Your thesis processor will then insert the internal banner lines as part of your final review.
If marking a heading as (FOUO), ensure that the heading text as it stands on its own does, indeed, require protection (a portion mark applies only to the portion that immediately follows). In other words, the mark does not serve to portend that the entire chapter or subsection carries the same protection; each applicable paragraph, caption, image, or subheading that contains FOUO information still must be portion marked.
Images and tables and their captions are treated as separate portion marks. It is possible for a table to be FOUO, while its caption is not, and vice versa.
