Contramedidas

Contramedidas (from contra, against, and medida, measure) are actions, technologies, and policies designed to detect, deter, prevent, or mitigate threats or vulnerabilities. In the Spanish and Portuguese lexicon, contramedidas is used similarly to the English term countermeasures. In practice, contramedidas aim to reduce risk by limiting the success of a threat or by reducing the potential impact of an attack or failure.

They are applied across diverse domains, including military and defense, cybersecurity, public safety, health and environmental risk management, and critical infrastructure protection. The design typically follows risk assessment: identify threats, analyze vulnerabilities, estimate potential impact, and select measures that balance effectiveness, cost, and social or legal implications. Measures can be preventive, detective, or responsive, and are often layered or integrated into systems.

Examples of contramedidas include information security controls (encryption, access control, monitoring), physical security measures (barriers, surveillance), policy frameworks and incident response plans, and public health practices (screening, vaccination campaigns, quarantine when appropriate). In environmental and climate contexts, they include mitigation and adaptation strategies aimed at reducing damages from hazards. The assessment of contramedidas emphasizes trade-offs, monitoring results, and the need for reassessment as threats evolve.

Limitations include imperfect effectiveness, operational costs, potential privacy or civil liberty concerns, and the risk of evasion or complacency. Successful deployment typically requires clear objectives, stakeholder coordination, governance, and ongoing evaluation.
