Sensitive but unclassified
From Wikipedia, the free encyclopedia
Sensitive But Unclassified (SBU) is a U.S. designation of information, often referred to as "Sensitive Homeland Security Information".
SBU is a broad category of information including For Official Use Only (FOUO), Law Enforcement Sensitive (LES), Security Sensitive Information (SSI), Critical Infrastructure Information (CII), etc.
Some categories of SBU information have authority in statute or regulation (e.g. SSI, CII) while others (FOUO) do not.
Documents are often marked FOUO/NO FORN, designating that they may not be disseminated to foreign persons or entities.
