Fix Recommendation

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.

Check Contents

Obtain the list of authorized Azure SQL Managed Instance accounts in the system documentation.

Determine if any accounts are shared. A shared account is defined as a username and password that are used by multiple individuals to log in to Azure SQL Managed Instance. Microsoft Entra ID groups are not shared accounts as the group itself does not have a password.

If accounts are to be shared, determine if users are first individually authenticated.

If users are not individually authenticated before using the shared account (e.g., by the operating system or possibly by an application making calls to the database), this is a finding.

The key is individual accountability. If this can be traced, this is not a finding.

If accounts are shared, determine if they are directly accessible to end users. If so, this is a finding.

Review contents of audit logs and data tables to confirm the identity of the individual user performing the action is captured.

If shared identifiers are found and not accompanied by individual identifiers, this is a finding.
