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
