Check Text ( C-33638r4_chk )
Query the SA and the Web Manager to determine if a compiler is present on the server. If a compiler is present, this is a finding. NOTE: If the web server is part of an application suite and a compiler is needed for installation, patching, and upgrading of the suite or if the compiler is embedded and can't be removed without breaking the suite, document the installation of the compiler with the ISSO/ISSM and verify that the compiler is restricted to administrative users only. If documented and restricted to administrative users, this is not a finding.

Fix Text (F-29279r4_fix)
Remove any compiler found on the production web server, but if the compiler program is needed to patch or upgrade an application suite in a production environment or the compiler is embedded and will break the suite if removed, document the compiler installation with the ISSO/ISSM and ensure that the compiler is restricted to only administrative users.
