A countermeasure is an action or strategy designed to counteract or mitigate a threat or problem. For example, in cybersecurity, organizations implement countermeasures like firewalls and encryption to protect sensitive data from cyberattacks. These measures help to reduce risks and enhance security, ensuring that information remains safe from unauthorized access. In military contexts, countermeasures can refer to tactics used to neutralize enemy actions. For instance, military forces might deploy decoys or jamming technology to confuse or disrupt an opponent's operations. By anticipating potential threats and responding effectively, countermeasures play a crucial role in maintaining safety and security across various fields.
