I am doing some security work on SQL server and am concerned about the permisions on the public role. i want to strip down the permisions given to the public role in the system databases. What are the implications of runnign scripts to revoke all to public for all statements and objects in all databases. I have read this causes problems? What have other folk done regarding this and is there a definitive list anywhere?

Thanks in advance
