Which term is not an industry standard but is important for establishing the necessary controls to protect data, such as security configurations and access controls?

The term that is not an industry standard but plays a critical role in establishing the necessary controls to protect data is the statement of classification. This term refers to the process of labeling data according to its sensitivity and the level of protection it requires. While it is essential for determining how data should be handled, stored, and accessed, it does not conform to a specific industry standard like the others listed.

Data sovereignty deals with the concept of data being subject to the laws and regulations of the country in which it is located, which is important for compliance but not a control mechanism by itself. Integration agreements typically outline how two systems will work together and are more technical in nature rather than focused on security controls. An attestation of compliance (AOC) is a formal document that provides evidence of compliance with specific standards, such as PCI DSS or other regulatory requirements, but it itself is not a direct tool for establishing controls.

Thus, the statement of classification is pivotal for informing how to protect data without being classified as an industry standard.
