Use this as standards implementation guidance for trust service providers. Notification duties still depend on the applicable regulatory rules and competent authorities for the service. Short answer: ETSI EN 319 401 treats security incidents as an operational evidence chain, not just an emergency playbook. A trust service provider should be able to show mechanisms for detecting potential incidents, response procedures for containment, eradication and recovery, reporting and communication procedures, event assessment and classification, vulnerability follow-up, and post-incident review. ## What does ETSI EN 319 401 require for security incidents? Clause 7.9 of ETSI EN 319 401 V3.1.1 is the core incident-management clause. It covers monitoring and logging, incident response, reporting, event assessment and classification, and post-incident reviews. The practical implication is that incident handling should be documented from detection through follow-up, with evidence that the process actually operates. The standard defines incident handling as actions and procedures to prevent, detect, analyse, contain, respond to, and recover from an incident. It also defines an information security incident as related and identified information security events that can harm assets or compromise operations, so the incident process should connect event intake, severity assessment, response, and lessons learned. - Detect potential security incidents through continuous monitoring and logging mechanisms for the TSP's network and information systems. - Maintain, document, and regularly review logs covering network traffic, user and permission administration, administrator activity, critical configuration and backup access or changes, security-relevant logs, resource use, and relevant physical, network-device, and environmental events. - Use incident response procedures that include containment, eradication, and recovery, then keep comprehensive documentation throughout detection and response. - Analyse reported events, assess severity, and be able to reassess and reclassify events when new inputs appear.

EN 319 401 expects incident handling to have assigned roles and communication paths. The TSP should maintain communication plans that include incident categorisation, escalation procedures, and standardised reporting protocols. Personnel also need the competencies to detect and respond to security incidents. For alerts of potentially critical security events, the standard calls for trusted role personnel to follow up and make sure relevant incidents are reported in line with the TSP's procedures. The incident function should also have clear interfaces with business continuity management so response and service restoration do not run as disconnected workstreams. - Name the incident owner, trusted role personnel, escalation path, and business continuity handoff before an incident occurs. - Keep stakeholder communication plans separate from ad hoc status updates; EN 319 401 expects agreed communication plans and standardised reporting protocols. - Train staff on the reporting procedure and communicate the reporting procedure to contractors and customers. - Test and review roles, responsibilities, and procedures regularly and after incidents.

EN 319 401 does not let teams replace legal analysis with a generic notification rule. It says the TSP shall comply with reporting obligations mandated by relevant legislative frameworks for network and information security incidents, including supervisory authorities and CSIRTs. For a breach of security or loss of integrity with significant impact on the trust service provided and on the personal data maintained in it, clause 7.9.3 requires procedures to notify appropriate parties in line with applicable regulatory rules within 24 hours of the breach being identified. The ETSI note says TSPs operating within the European Union can contact the appropriate supervisory body or other competent authorities for guidance on notification procedures under eIDAS Article 19.2. - Do not claim every incident has the same external notification path; first classify the event and identify the applicable regulatory rule. - Keep procedures for notifying appropriate parties when there is a significant-impact breach of security or loss of integrity affecting the trust service and related personal data. - Notify affected natural or legal persons without undue delay when the breach is likely to adversely affect the person to whom the trust service was provided. - Maintain a simple reporting procedure for staff, contractors, and customers to report possible network and information security incidents.

A useful EN 319 401 incident file should show the full chain: event source, severity assessment, classification changes, response actions, stakeholder communication, vulnerability handling, continuity coordination, and post-incident review. This keeps the page focused on evidence that a trust service provider can maintain and show to assessors or customers. Post-incident work should not stop at closure notes. Clause 7.9.5 requires the TSP to keep informed about technical vulnerabilities, evaluate its exposure, take appropriate measures, identify incident root cause, conduct post-incident reviews, and ensure each past incident led to a post-incident review. - Monitoring evidence: alert records, log-review records, and the log categories covered by the monitoring process. - Response evidence: containment, eradication, recovery, owner decisions, communication records, and business continuity handoffs. - Reporting evidence: regulatory-rule assessment, appropriate-party notification records where applicable, and staff, contractor, or customer intake records. - Review evidence: root-cause analysis, vulnerability exposure assessment, mitigation plan or documented no-remediation basis, and proof that the post-incident review occurred.
