Article 34 Communication à la personne concernée d'une violation de données à caractère personnel

-

1. Vue d’ensemble

,
Article 34 1.
Lorsqu'une violation de données à caractère personnel est susceptible d'engendrer un risque élevé pour les droits et libertés d'une personne physique, le responsable du traitement communique la violation de données à caractère personnel à la personne concernée dans les meilleurs délais.
Article 34 2.
La communication à la personne concernée visée au paragraphe 1 du présent article décrit, en des termes clairs et simples, la nature de la violation de données à caractère personnel et contient au moins les informations et mesures visées à l'article 33, paragraphe 3, points b), c) et d).
Article 34 3.

La communication à la personne concernée visée au paragraphe 1 n'est pas nécessaire si l'une ou l'autre des conditions suivantes est remplie:

a) 

le responsable du traitement a mis en œuvre les mesures de protection techniques et organisationnelles appropriées et ces mesures ont été appliquées aux données à caractère personnel affectées par ladite violation, en particulier les mesures qui rendent les données à caractère personnel incompréhensibles pour toute personne qui n'est pas autorisée à y avoir accès, telles que le chiffrement;

b) 

le responsable du traitement a pris des mesures ultérieures qui garantissent que le risque élevé pour les droits et libertés des personnes concernées visé au paragraphe 1 n'est plus susceptible de se matérialiser;

c) 

elle exigerait des efforts disproportionnés. Dans ce cas, il est plutôt procédé à une communication publique ou à une mesure similaire permettant aux personnes concernées d'être informées de manière tout aussi efficace.
Article 34 4.
Si le responsable du traitement n'a pas déjà communiqué à la personne concernée la violation de données à caractère personnel la concernant, l'autorité de contrôle peut, après avoir examiné si cette violation de données à caractère personnel est susceptible d'engendrer un risque élevé, exiger du responsable du traitement qu'il procède à cette communication ou décider que l'une ou l'autre des conditions visées au paragraphe 3 est remplie.

SCR-CMM

Level 0 Not Performed

Practices are non-existent, based on the inability to demonstrate an implemented and operational capability. A reasonable person would conclude the control is not being performed.

Level 1 Performed Informally

SCR-CMM Level 1 criteria definitions are not available for this control:
▪ A reasonable person would conclude this control requires a structured process.
▪ At this level of maturity, the "ad hoc" nature of performing a capability informally would indicate the intent of the control is not met due to a lack of consistency and formality.

Level 2 Planned Tracked

Incident Response (IRO) capabilities are requirements-driven, but are not standardized across the entity (e.g., local/regional level consistency). Capability criteria associated with this control reasonably expect the following criteria to exist:
▪ Policies and standards associated with IRO domain capabilities are formally documented and centrally-managed by the entity.
▪ Standardized Operating Procedures (SOP) associated with DCH domain capabilities are documented and maintained by process owners.
▪ IT and/or cybersecurity personnel work with business stakeholders and process owners to appropriately scope and reasonably implement cybersecurity and data protection controls associated with IRO domain capabilities to address applicable statutory, regulatory and/or contractual requirements for Technology Assets, Applications, Services and/or Data (TAASD).
▪ Incident response-related controls are primarily administrative and preventative in nature (e.g., policies, standards and procedures & guidelines).
▪ Incident response management may be a defined function (e.g., team or department) or assigned as an additional duty to existing IT and/or cybersecurity personnel.
▪ IT and/or cybersecurity personnel operate an incident response capability using a documented and tested Incident Response Plan (IRP) to facilitate incident management operations that cover preparation, detection and analysis, containment, eradication and recovery.
▪ Incident responders are proficient on their specific IRP role(s) and responsibilities through recurring training events (e.g., annual rock drill).

Level 3 Well Defined

Incident Response (IRO) capabilities are standardized across the entity for applicability to People, Processes, Technologies, Data and/or Facilities (PPTDF) to ensure consistency for Technology Assets, Applications, Services and/or Data (TAASD). Capability criteria associated with this control reasonably expect the following criteria to exist:
▪ Policies and standards associated with IRO domain capabilities are formally documented and centrally-managed by the entity's Governance, Risk & Compliance (GRC) team, or similar function.
▪ Cybersecurity personnel operate an incident response capability using a documented and tested Incident Response Plan (IRP) to facilitate incident management operations that cover preparation, detection and analysis, containment, eradication and recovery.
▪ An incident response team, or similar function, is appropriately staffed and supported to implement and maintain IRO domain capabilities.
▪ Technology is leveraged to enhance the efficiency and accuracy of incident response operations (e.g., incident management software).
▪ The entity's Governance, Risk & Compliance (GRC) team, or similar function, works with business stakeholders and process owners to appropriately scope and reasonably implement cybersecurity and data protection controls associated with IRO domain capabilities to address Minimum Compliance Requirements (MCR) (e.g., applicable statutory, regulatory and/or contractual requirements) and Discretionary Security Requirements (DSR) (e.g., entity-required controls).
▪ An implemented and operational capability exists to train personnel in their incident response roles and responsibilities.

Level 4 Quantitatively Controlled

Incident Response (IRO) capabilities, in addition to being standardized across the entity and centrally managed to ensure consistency across Technology Assets, Applications, Services and/or Data (TAASD), efforts are metrics driven to provide sufficient insight for decision makers to predict optimal performance, ensure continued operations and/or identify areas for improvement. Capability criteria associated with this control reasonably expect the following criteria to exist:
▪ Applicable SCR-CMM Level 3 (Well Defined) capabilities are implemented and operational.
▪ Metrics reporting includes quantitative analysis of Key Performance Indicators (KPIs).
▪ Metrics reporting includes quantitative analysis of Key Risk Indicators (KRIs).
▪ Scope of metrics, KPIs and KRIs covers organization-wide cybersecurity and data protection controls, including functions performed by third-parties.
▪ Organizational leadership maintains a formal process to objectively review and respond to metrics, KPIs and KRIs (e.g., monthly or quarterly review).
▪ Based on metrics analysis, process improvement recommendations are submitted for review and are handled in accordance with change control processes.
▪ Business and technical stakeholders are involved in reviewing and approving proposed changes to evolve capabilities.

Level 5 Continuously Improving

Utilize SCR-CMM Level 3 or Level 4 (if available) criteria definitions:
▪ There are no defined Level 5 criteria, since it is reasonable to assume a continuously-improving process is not necessary to operationalize this control.
▪ Level 5 capabilities should be considered “world-class” where the control builds on Level 4 capabilities, but are continuously improving through Artificial Intelligence (AI) and/or Machine Learning (ML) technologies.
▪ While it may be possible to develop responsive capabilities for this control through the use of AI and/or ML technologies, the criteria would be organization-specific to define.
