SLES security and support

Hello, I'm new here and am considering using SLES in a deliverable product
and have a couple of questions.

Does SLES-11.0 have any sort of "official" IE C1 etc.. or any other
industry recognized security certification? If so, would installing
software not in any official Novell repository or certified by Novell
breach that certificataion or its support policies?

If this is not the correct place to ask such, could I be directed to the
proper place?

Thanks in advance
