Royal Decree 311/2022, of 3 May Major version
The new National Security Framework, published in BOE no. 106 of 4 May 2022 and in force from 5 May 2022; it repealed Royal Decree 3/2010. source
Who it applies to
The ENS binds the entire Spanish public sector and reaches private contractors through their public contracts and, where the risk analysis requires it, their supply chain.
- Public sector
- The whole public sector as defined in Article 2 of Law 40/2015, plus systems that handle classified information (Article 2(1)-(2)). source
- Private contractors
- Information systems of private entities that provide services or solutions to public sector entities under a contract, including the duty to have a security policy (Article 2(3)). source
- Tender documents
- Public contracts must include the requirements to ensure ENS conformity, such as declarations or certifications of conformity, extended to the supply chain as needed. source
- Categories
- Systems are classified in three security categories, BASIC, MEDIUM and HIGH (Article 40 and Annex I), which set the security measures of Annex II that apply. source
How compliance is assessed
MEDIUM and HIGH systems need a certification audit, BASIC systems a self-assessment, and every system an ordinary security audit at least every two years.
- Certification or declaration
- MEDIUM or HIGH category systems need an audit to certify ENS conformity; BASIC systems need only a self-assessment for a declaration of conformity (Article 38(1)). source
- Audit every two years
- Systems undergo a regular ordinary audit at least every two years, and an extraordinary one after substantial changes (Article 31(1)). source
- Publication
- Declarations and certifications of conformity must be published on the entity's website or electronic office (Article 38(2)). source
- Incident notification
- Public sector entities notify the CCN of incidents with a significant impact on the security of their systems (Article 33(2)). source
Enforcement and penalties
The ENS is enforced through audits, published conformity, CCN reporting and public contract terms; for HIGH systems serious audit findings can lead to suspension.
- Suspension
- For HIGH category systems, the system owner may temporarily suspend processing or services until serious audit deficiencies are fixed (Article 31(6)). source
- Audit reports
- Audit reports may be requested by each organisation's IT security officials and by the CCN (Article 31(7)). source
- State of security report
- The CCN collects and consolidates information on the state of security of in-scope systems for a report used by the competent authorities (Article 32). source
