Electronic countermeasures training teaches individuals methods of foiling a variety of potentially offensive electronic technologies. These include the use of signal jammers to disrupt frequencies that could be used to detonate explosive devices, and methods of foiling electronic surveillance technologies.
Training in electronic countermeasures is given by the government and military to those individuals in fields where such knowledge is necessary. These include federal agents and military personnel. Training programs in these techniques are also available through a number of colleges and security firms.
While anyone can seek out training in electronic countermeasures, it is most useful to those in the field of security. Additionally, the cost of training and the equipment necessary to use that training, makes the training most economical for those who will use the knowledge professionally.
