What is the primary role of a data controller within an organization?

The primary role of a data controller within an organization is to ensure compliance with data protection laws. This involves the responsibility of determining the purposes for which and the manner in which personal data is processed. Data controllers must implement appropriate measures and policies to protect personal data and ensure that it is handled in accordance with legal requirements such as the General Data Protection Regulation (GDPR).

This role is pivotal in safeguarding individuals' rights regarding their personal information, overseeing data processing activities, and ensuring that data is not misused or improperly shared. A data controller must also manage the organization's data processing activities in a way that maintains transparency and accountability, taking necessary actions to avoid data breaches and comply with regulatory obligations.

The other options focus on aspects that do not encapsulate the essence of a data controller's duties. Collecting all possible data does not align with the principles of data minimization and necessity that are vital in data protection laws. Managing IT infrastructure and providing technical support are functions often associated with IT departments rather than the mandatory compliance-focused role of a data controller.
