Risk Assessment

Data Risk Evaluation

Risk management is a widely used tool across various industries, and in the context of Data Protection Impact Assessments (DPIAs), its focus is specifically on risks to data subjects rather than the risks faced by the data controller.

Understanding Risks in DPIA

Article 35(7)(c) of the GDPR mandates an assessment of “risks to the rights and freedoms of data subjects.” Recital 75 expands on this, clarifying that risks include physical, material, and non-material damage. The WP29 (now the EDPB) emphasizes that risks in a DPIA go beyond privacy concerns and can impact a broad range of fundamental rights, such as:

Three Primary Sources of Risk

Illegitimate Access

Unauthorized access to personal data.

Undesired Modification

Alteration of personal data in an unapproved way.

Disappearance of Data

Data loss or destruction.

Conducting the Risk Assessment

The risk analysis process involves:

identification
Identifying risk sources
Determining potential threats to data subjects.
Estimating impact and probability
Assessing how significant a risk is and how likely it is to occur.
Determining risk levels
Categorizing risks based on severity to decide if further mitigation is required.

Risk Assessment Methodology

Recital 76 of the GDPR emphasizes that risk must be evaluated through an objective assessment, yet it does not prescribe a specific framework. Organizations are encouraged to establish and consistently apply their own methodology, ensuring transparency and accountability in every DPIA process. The Belgian Supervisory Authority further notes that each organization must formally define its risk assessment approach and apply it uniformly across all processing operations.

Documenting Risk Decisions for Compliance

Neither the GDPR nor the WP29 guidance defines a fixed threshold for what constitutes “high risk.”
Organizations must therefore carefully document their risk evaluations, explain how they determined risk levels, and justify decisions made during each DPIA. Comprehensive records provide evidence of compliance and demonstrate accountability to Supervisory Authorities.
