ENS (Esquema Nacional de Seguridad)
Definition
ENS is the Spanish National Security Framework: a legally required security framework for Spanish government organizations and their suppliers.
ENS (Esquema Nacional de Seguridad) is the Spanish National Security Framework: a legally mandatory security framework for all Spanish government organisations and their ICT suppliers. It is the Spanish equivalent of frameworks like ISO 27001.
How does ENS work?
ENS is based on three security pillars: confidentiality, integrity and availability. The framework sets requirements for risk management, security policy and organisation, identity and access management, communication and information protection, incident management and continuity, and monitoring and auditing. Organisations are classified into three security categories (basic, medium, high) based on potential incident impact.
Impact on organisations
All Spanish government organisations and their ICT suppliers must comply with ENS. For Dutch and other European companies serving the Spanish government, ENS compliance is a contractual requirement. ENS aligns with NIS2 and ISO 27001 but has Spain-specific requirements.
Protection
Conduct risk analysis per ENS methodology. Implement security measures appropriate for the security category. Conduct regular audits and document compliance.
