Check: GEN001680

SUSE Linux Enterprise Server v11 for System z STIG: GEN001680 (in versions v1 r12 through v1 r9)

Title

All system start-up files must be group-owned by root, sys, bin, other, or system. (Cat II impact)

Discussion

If system start-up files do not have a group owner of root or a system group, the files may be modified by malicious users or intruders.

Check Content

Check run control scripts' group ownership. Procedure: # ls -lL /etc/rc* /etc/init.d Alternatively: # find /etc -name "[SK][0-9]*"|xargs stat -L -c %G:%n|egrep -v "^(root|sys|bin|other):" If any run control script is not group-owned by root, sys, bin, or other system groups, this is a finding.

Fix Text

Change the group ownership of the run control script(s) with incorrect group ownership. Procedure: # chgrp root <run control script> # find /etc -name "[SK][0-9]*"|xargs stat -L -c %G:%n|egrep -v "^(root|sys|bin|other):"|cut -d: -f2|xargs chgrp root
