Flares are often used to distract infrared homing missiles to miss their target. The use of flare rejection logic in the guidance (seeker head) of an infrared homing missile to counter an adversary's use of flares is an example of EP. While defensive EA actions (jamming) and EP (defeating jamming) both protect personnel, facilities, capabilities, and equipment, EP protects from the "effects" of EA (friendly and/or adversary). Other examples of EP include spread spectrum technologies, use of restricted frequency lists, emissions control (EMCON), and low observability (stealth) technology.
