CNSIC is Brazil’s committee responsible for setting policy direction for critical-infrastructure protection. In the context of Resolution No. 20, it issued new guidelines that define how essential sectors should organize monitoring, coordination, and risk awareness. This makes CNSIC part of the governance layer of cyber security, where rules, responsibilities, and escalation paths are established before an incident happens.
This matters because attacks on critical infrastructure often succeed by exploiting weak coordination, slow reporting, or unclear authority rather than only technical flaws. A committee like CNSIC can help standardize how threats are identified, shared, and escalated across agencies and operators. In practice, its guidance can shape defenses such as incident reporting procedures, dependency mapping, and cross-sector response planning, improving resilience when systems that support power, communications, transport, or public services are targeted.
