Discussion

When dealing with change control issues, it should be noted any changes to the hardware, software, and/or firmware components of the information system and/or application can have significant effects on the overall security of the system. If the system were to allow any user to make changes to software libraries, then those changes might be implemented without undergoing the appropriate testing and approvals that are part of a robust change management process. Accordingly, only qualified and authorized individuals must be allowed access to information system components for purposes of initiating changes, including upgrades and modifications. DBA and other privileged administrative or application owner accounts are granted privileges that allow actions that can have a great impact on SQL Server security and operation. It is especially important to grant privileged access to only those persons who are qualified and authorized to use them.

sl "C:\Program files\Microsoft SQL Server\160\Setup Bootstrap\Log" 
Get-ChildItem -Recurse | Select-String -Pattern "LogonUser = " 
 
If any accounts are shown that are not authorized in the system documentation, this is a finding.
