SV-53950r2_rule SQL Server must prevent unauthorized and unintended information transfer via shared system resources.

Vulnerability discussion

The purpose of this control is to prevent information, including encrypted representations of information, produced by the actions of a prior user/role (or the actions of a process acting on behalf of a prior user/role) from being available to any current user/role (or current process) that obtains access to a shared system resource (e.g., registers, main memory, secondary storage) after the resource has been released back to the information system. Control of information in shared resources is also referred to as object reuse.Data used for the development and testing of applications often involves copying data from production. It is important that specific procedures exist for this process, so copies of sensitive data are not misplaced or left in a temporary location without the proper controls.

Check content

Verify there are proper procedures in place for the transfer of development/test data from production. Review any scripts or code that exists for the movement of production data to development/test and verify copies of production data are not left in unprotected locations. If there is no documented procedure for data movement from production to development/test, this is a finding. If data movement code that copies from production to development/test does exist and leaves any copies of production data in unprotected locations, this is a finding.

Fix text

Create and document a process for moving data from production to development/test systems and follow the process. Modify any code used for moving data from production to development/test systems to ensure copies of production data are not left in unsecured locations.

Pro Tips

Lavender hyperlinks in small type off to the right (of CSS class id, if you view the page source) point to globally unique URIs for each document and item. Copy the link location and paste anywhere you need to talk unambiguously about these things.

You can obtain data about documents and items in other formats. Simply provide an HTTP header Accept: text/turtle or Accept: application/rdf+xml.
