It is not always clear, under this doctrine, who is responsible for all intelligence collection threats against a military or other resource. The full scope of US military counterintelligence doctrine has been moved to a classified publication, Joint Publication (JP) 2-01.2, Counterintelligence and Human Intelligence Support to Joint Operations, so publicly it is unknown if that problem is clarified there. Countermeasures to specific collection disciplines More specific countermeasures against intelligence collection disciplines are listed below Counter-HUMINT See additional detail on Project Slammer, which was an effort of the Intelligence Community Staff, under the Director of Central Intelligence, to come up with characteristics of Project Slammer, an Intelligence Community sponsored study of espionage. Aspects of physical security, such as guard posts and wandering guards that challenge unidentified persons, certainly help with counter-HUMINT. Security education, also part of OPSEC, is important to this effort. Counter-SIGINT Military and security organizations will provide secure communications, and may monitor less secure systems, such as commercial telephones or general Internet connections, to detect inappropriate information being passed through them. Education on the need to use secure communications, and instruction on using them properly so that they do not become vulnerable to specialized technical interception. Methods of including encryption and traffic flow security may be needed in addition to, or instead of, specialized shielding of the equipment. The range of methods possible in counter-SIGINT cover a wide range of what is appropriate in a combat zone to what can be done in a research laboratory. At the combat end, if an enemy SIGINT interception antenna can be targeted, thoroughly bombing it and its associated electronics will definitely end its career as a SIGINT threat. In slight less dramatic fashion, it can be taken under electronic attack, and strong enough electromagnetic signals directed at it to conceal any friendly signals, and perhaps to overload and destroy the electronics of the SIGINT facility. SIGINT protection for office buildings may require a room to be electronically shielded. Counter-IMINT The basic methods of countering IMINT are to know when the opponent will use imaging against one's own side, and interfering with the taking of
