Countermeasure systems are technologies designed to detect, deter, or neutralize threats, particularly in military and security contexts. These systems can include various methods such as electronic jamming, decoys, and interceptors, which aim to protect assets from attacks, such as missiles or drones. In addition to military applications, countermeasure systems are also used in civilian sectors, like aviation and cybersecurity. For instance, aircraft may employ countermeasures to avoid radar detection, while firewalls and encryption serve as digital countermeasures to protect sensitive information from cyber threats.
