Logging Database-Level Security Commands

Kenneth Fisher keeps the receipts:

In my last post I talked about reasons why your permissions might go missing. One of the reasons, and in my experience, one of the more unusual reasons, is that a command was run that changed the permissions. SQL doesn’t natively log these. Well, technically it does. They can be found in the default trace. But I don’t generally consider that to be terribly useful because on a busy server what’s available in the default trace may not last long. Regardless I ended up creating a DDL trigger to collect any database level security commands run. There are other ways to do this but for various reasons I decided to go with a trigger. Primarily because I could create one piece of code and cover every database in the instance.

Read on to learn how to create an appropriate table and a trigger to log that data.
