All commands which receive TSCM services must implement OPSEC measures to ensure the success of the countermeasures effort. Assume, until the survey indicates otherwise, that a technical surveillance device is actually in place.<\/p>\n\n\n\n<p>(2) Should discussions concerning pending support take place within the space, the device would most likely be removed prior to the survey and later reinstalled, or simply deactivated remotely. Under such circumstances, the probability of locating a technical surveillance device is diminished greatly. For this reason, no discussion or verbal comments concerning pending TSCM support shall take place in the spaces of concern, nor shall discussions or verbal comments take place during the survey.<\/p>\n\n\n\n<p>(3) Telephone requests or discussions of scheduled TSCM support are considered compromising unless conducted over secure voice systems outside the facility to be serviced. Similarly, e-mail messages referencing anticipated or occurring TSCM services originating from or going to the concerned spaces will also be considered a compromise of the services.<\/p>\n\n\n\n<p>Source: United States Marine Corps: Technical Surveillance Countermeasures (TSCM) program, I MEFO 5511 (2011.)<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"693\" height=\"145\" src=\"https:\/\/sigint.hr\/wp-content\/uploads\/2021\/10\/Sun_Tzu_engleski.png\" alt=\"\" class=\"wp-image-723\" srcset=\"https:\/\/sigint.hr\/wp-content\/uploads\/2021\/10\/Sun_Tzu_engleski.png 693w, https:\/\/sigint.hr\/wp-content\/uploads\/2021\/10\/Sun_Tzu_engleski-300x63.png 300w, https:\/\/sigint.hr\/wp-content\/uploads\/2021\/10\/Sun_Tzu_engleski-18x4.png 18w\" sizes=\"auto, (max-width: 693px) 100vw, 693px\" \/><\/figure>","protected":false},"excerpt":{"rendered":"<p>U\u010dinkovitost posebnih mjera tehni\u010dke za\u0161tite zna\u010dajno se temelji na elementima Operativne sigurnosti (OPSEC), odnosno za\u0161titi informacija o planiranju provo\u0111enja mjera i postizanju takti\u010dkog iznena\u0111enja. *** (1) Posebne mjere tehni\u010dke za\u0161tite (TSCM) predstavljaju specijalizirana protuobavje\u0161tajna istra\u017eivanja i kao takva su posebno osjetljiva na kompromitacije.
