Check Text ( C-19578r377306_chk )
The following command will list which files on the system have group-ownership different from what is expected by the RPM database: # rpm -Va | grep '^......G' If any output is produced, verify that the changes were due to STIG application and have been documented with the ISSO. If any output has not been documented with the ISSO, this is a finding.

Fix Text (F-19576r377307_fix)
The RPM package management system can restore group-ownership of the package files and directories. The following command will update files and directories with group-ownership different from what is expected by the RPM database: # rpm -qf [file or directory name] # rpm --setugids [package]
