What document outlines the rules and guidelines governing data classification within an organization?

The document that outlines the rules and guidelines governing data classification within an organization is the Data Classification Policy. This policy is specifically designed to establish a framework for categorizing data based on sensitivity, value, and criticality to the business. It helps organizations determine how to handle and protect different types of data, ensuring that sensitive information receives higher levels of security and access controls.

The Data Classification Policy typically defines various classifications (for example, public, internal, confidential, and restricted) and provides criteria for classifying data appropriately. This structured approach enhances both compliance with regulations and internal governance, facilitating better risk management practices concerning data security.

Other documents mentioned, such as the Data Handling Policy and Information Security Policy, may address broader topics related to how data should be processed and protected, but they do not focus exclusively on the classification of data itself. Information Handling Procedures are often associated with practical steps for managing data but do not set the overarching classification guidelines as the Data Classification Policy does. Overall, the specificity and focus of the Data Classification Policy make it the correct answer.
