Disable public security group on SQL Server

[gantta_del]

Running on-premise Power BI in a highly regulated environment, security scans flagged the Public security group as a vulnerability and we are looking for work arounds to pass the audit. I'm having a hard time finding any information regarding the usage of the Public security group and the effects if we removed the group. 

Short of just removing it and seeing how the system responds, does anyone have any suggestions or experience with disabling or removing the Public security group?

Hi @gantta_del ,

Specifically for security groups what is the vulnerability, can you provide screenshots of that and explain it.

Also for security groups, it is the IT administrator who creates and maintains these groups. Specific information about security groups can be found in the following blog.

 Looking forward to your reply.

Thanks for the link, but I'm looking specifically at the SQL Server Database security groups. I wasn't present when the Power BI service was initially installed, but our team has inherited responsibility for managing the service. 

As I understand it, the Power BI installation running on a VM comes out of the box with a SQL Server database security group named Public. The vulnerability test identified this group as invalid and should look to create permissions based on least-privileged requests for the security groups.
