Check: GEN006150

SUSE Linux Enterprise Server v11 for System z STIG: GEN006150 (in versions v1 r12 through v1 r9)

Title

The /etc/smb.conf file must not have an extended ACL. (Cat II impact)

Discussion

Excessive permissions could endanger the security of the Samba configuration file and, ultimately, the system and network.

Check Content

Check the permissions of the Samba configuration file. # ls -lL /etc/samba/smb.conf If the permissions include a '+', the file 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 file. # setfacl --remove-all /etc/samba/smb.conf
