Which of the following should be established FIRST so that data owners can consistently assess the level of data protection needed across the enterprise?

A data classification policy is the foundational element required to consistently assess data protection needs. This policy establishes a framework for categorizing data based on its sensitivity, criticality, and value to the enterprise (e.g., Public, Confidential, Restricted). By creating a standardized set of criteria, the policy enables data owners to make uniform and objective decisions about the appropriate level of security controls, such as access rights and encryption, that must be applied. All other data protection activities, including risk management and the implementation of specific controls, are dependent on this initial classification.

A. Data encryption program: This is a specific security control. The decision on what data to encrypt and the strength of encryption required is determined after the data has been classified.

B. Data risk management program: A risk management program assesses threats and vulnerabilities, but it requires data classification as a primary input to determine the business impact of a potential data compromise.

C. Data retention policy: This policy defines how long data is kept. While important for governance, it is typically informed by the data's classification, not the other way around.
