What does CIS Control 3 emphasize regarding data?

CIS Control 3 emphasizes securing the entire lifecycle of data, which encompasses various stages such as data creation, storage, transmission, and destruction. This means ensuring that data is adequately protected from unauthorized access or loss throughout its lifespan, thereby maintaining its confidentiality, integrity, and availability.

The lifecycle approach encompasses applying appropriate security measures at each phase. For instance, encryption might be implemented during transmission, access controls might be established during storage, and secure deletion practices would be necessary for data that is no longer needed. This holistic view is essential for managing risks related to data security effectively.

In contrast, while minimizing the amount of data stored addresses data management and potential exposure, it does not specifically engage with the comprehensive security measures required across the entire lifecycle. Restricting data access solely to IT staff could hinder productivity and collaboration, as many stakeholders might need access based on their roles. Consolidating all data into a central database may enhance efficiency and reporting but doesn't inherently secure the data throughout its lifecycle.
