Last month the Director of National Intelligence issued a new Intelligence Community Directive (ICD) on “Technical Surveillance Countermeasures” (pdf) (TSCM).

TSCM “represents the convergence of two distinct disciplines — counterintelligence and security countermeasures,” the directive explained. Its purpose is “to detect and nullify a wide variety of technologies used to gain unauthorized access to classified national security information, restricted data, or otherwise sensitive information.”

The directive was released (in a fuzzy, not very well scanned copy) by the ODNI Freedom of Information Act office.
