According to GDPR, what should be done with data to ensure its confidentiality, integrity, and availability?

According to the General Data Protection Regulation (GDPR), a Data Protection Impact Assessment (DPIA) is a formal process designed to identify and minimize the data protection risks of a project or plan. Article 35 of the GDPR mandates a DPIA for processing that is "likely to result in a high risk to the rights and freedoms of natural persons." This assessment systematically evaluates the potential impact on data subjects and ensures that appropriate measures are in place to protect personal data, thereby addressing its confidentiality, integrity, and availability (CIA).

A. A vulnerability assessment is a technical activity that can be part of implementing security measures, but the DPIA is the overarching GDPR process for risk assessment.
C. Penetration testing is a specific method for testing security controls; it is not the comprehensive assessment process required by GDPR to ensure CIA.
D. Awareness testing focuses on the human element of security and is only one component of the broader technical and organizational measures evaluated in a DPIA.
