Spain Royal Decree 311/2022 — National Security Scheme (ENS)

Why it Matters

The Spain Royal Decree 311/2022 — National Security Scheme (ENS) establishes a unified security framework to safeguard public sector digital systems and data.

Key benefits include:

• Strengthen cybersecurity governance

Clarifies roles, responsibilities, and baseline security measures, enabling consistent decision-making and risk management across public sector entities.

• Improve regulatory compliance

Facilitates adherence to national and European legal requirements, reducing risk of penalties and supporting trust in digital services.

• Enhance operational resilience

Requires robust controls and contingency planning to reduce service disruptions and protect critical government operations from evolving cyber threats.

• Increase incident response readiness

Mandates systematic monitoring and clear response procedures, enabling early detection and rapid mitigation of security incidents.

• Promote protection of sensitive data

Implements stringent controls around data handling and access, minimizing unauthorized disclosure and ensuring citizen information is appropriately safeguarded.

How it Works

Spain's Royal Decree 311/2022 establishes the National Security Scheme (ENS), which structures its requirements into a comprehensive set of security principles, measures, and controls. The ENS organizes these safeguards within control families, addressing areas such as organizational framework, protective measures, and continuous improvement. Its framework further outlines three graded compliance categories—basic, medium, and high—tailoring security requirements to the risk profile and sensitivity of information handled by public sector entities and related organizations.

Organizations implement ENS by evaluating their current security posture, conducting risk assessments, and mapping operational practices to the prescribed control catalog. They deploy required security controls, adapt policies and procedures to ENS standards, and embed risk management processes into day-to-day operations. Ongoing activities include maintaining governance structures, conducting periodic compliance reviews, monitoring control effectiveness, and documenting evidence for regulatory oversight.

SmartSuite enables organizations to manage ENS operationalization through features such as a control library aligned to ENS requirements, automated risk registers, and policy governance modules. Users can track compliance status, collect supporting evidence, and facilitate audit readiness through centralized dashboards. The platform also supports remediation workflows and reporting tools, helping organizations maintain security practices and demonstrate ongoing compliance with the National Security Scheme.

Key Elements

• Security Measures Categories

Groups controls into logical areas such as organizational, operational, and protective security requirements.

• Risk Assessment Processes

Establishes procedures for identifying, analyzing, and addressing risks to information assets and services.

• Security Dimensions Classification

Defines the framework's structural pillars: confidentiality, integrity, availability, authenticity, and traceability.

• Maturity and Assurance Levels

Describes assurance tiers that determine the depth and rigor of required security measures.

• Governance and Policy Framework

Specifies mechanisms for management oversight, compliance, and the establishment of security policies.

• Asset Identification and Inventory

Organizes systematic approaches for cataloging, classifying, and maintaining information and technology assets.

• Incident Management Structure

Outlines protocols for preparing, reporting, and responding to cybersecurity incidents within the organization.

Framework Scope

Spain Royal Decree 311/2022 — National Security Scheme (ENS) is adopted by Spanish public sector entities and third parties managing government information or services. It governs the security controls of information systems and electronic services, and is typically leveraged for complying with regulatory mandates, enhancing operational resilience, and supporting cybersecurity and compliance oversight.
