Azure SQL Database must protect against a user falsely repudiating by ensuring only clearly unique Active Directory user accounts can connect to the database.
An XCCDF Rule
Description
Nonrepudiation of actions taken is required in order to maintain data integrity. Examples of particular actions taken by individuals include creating information, sending a message, approving information (e.g., indicating concurrence or signing a contract), and receiving a message. Nonrepudiation protects against later claims by a user of not having created, modified, or deleted a particular data item or collection of data in the database. In designing a database, the organization must define the types of data and the user actions that must be protected from repudiation. The implementation must then include building audit features into the application data tables and configuring Azure SQL Database's audit tools to capture the necessary audit trail. Design and implementation also must ensure that applications pass individual user identification to Azure SQL Database, even where the application connects to Azure SQL Database with a standard, shared account.

A Manual Procedure
Remove user-accessible shared accounts and use individual user IDs.
Build/configure applications to ensure successful individual authentication prior to shared account access.
Ensure each user's identity is received and used in audit data in all relevant circumstances.
Design, develop, and implement a method to log use of any account to which more than one person has access. Restrict interactive access to shared accounts to the fewest persons possible.
