Countersurveillance refers to measures that are usually undertaken by the public to prevent surveillance, [1] including covert surveillance.Countersurveillance may include electronic methods such as technical surveillance counter-measures, which is the process of detecting surveillance devices.
Directional Infrared Counter Measures (DIRCM) are a class of anti-missile systems produced to protect aircraft from infrared homing missiles, primarily MANPADS and similar simple systems. Earlier infrared countermeasures like flares or hot block systems that produce random flashes of IR light are semi- or omnidirectional.
Electronic counter-countermeasures (ECCM) is a part of electronic warfare which includes a variety of practices which attempt to reduce or eliminate the effect of electronic countermeasures (ECM) on electronic sensors aboard vehicles, ships and aircraft and weapons such as missiles.

An ALQ-144 jammer mounted on an OV-10 Bronco.. The AN/ALQ-144, AN/ALQ-147, and AN/ALQ-157 are US infrared guided missile countermeasure devices ().They were developed by Sanders Associates in the 1970s to counter the threat of infrared guided surface-to-air missiles like the 9K32 Strela-2.
An electronic countermeasure (ECM) is an electrical or electronic device designed to trick or deceive radar, sonar, or other detection systems, like infrared (IR) or lasers. It may be used both offensively and defensively to deny targeting information to an enemy.
An infrared countermeasure (IRCM) is a device designed to protect aircraft from infrared homing ("heat seeking") missiles by confusing the missiles' infrared guidance system so that they miss their target (electronic countermeasure). Heat-seeking missiles were responsible for about 80% of air losses in Operation Desert Storm.
IED Countermeasure Equipment (ICE): In the fall of 2004, the Army Research Laboratory (ARL) at White Sands Missile Range in New Mexico and New Mexico State University's Physical Science Laboratory developed a jamming system that uses low-power radio frequency energy to block the radio signals that detonate enemy IEDs.
