Check: GEN000930

SUSE Linux Enterprise Server v11 for System z STIG: GEN000930 (in versions v1 r12 through v1 r9)

Title

The root accounts home directory must not have an extended ACL. (Cat II impact)

Discussion

File system extended ACLs provide access to files beyond what is allowed by the unix permissions of the files.

Check Content

Check the root account's home directory has no extended ACL. # grep "^root" /etc/passwd | awk -F":" ‘{print $6}’ # ls -ld <root home directory> If the permissions include a '+' the directory has an extended ACL. If the file has an extended ACL and it has not been documented with the IAO, this is a finding.

Fix Text

Remove the extended ACL from the root account's home directory. # setfacl --remove-all <root home directory>
