Countermeasure refers to actions, strategies, or interventions implemented to prevent or mitigate the negative impact of a specific threat or risk. In research, countermeasures are often used to address vulnerabilities, weaknesses, or potential security breaches within systems, processes, or technologies. These countermeasures aim to enhance the resilience and security of the target system by minimizing the likelihood or severity of a harmful event or attack. Countermeasures can include technical solutions, procedural changes, training programs, and other measures designed to protect against potential threats. The effectiveness of countermeasures is typically assessed through risk assessments, simulation exercises, testing, and monitoring to ensure optimal protection and mitigation of risks.
