Check: GEN001190

SUSE Linux Enterprise Server v11 for System z STIG: GEN001190 (in versions v1 r12 through v1 r9)

Title

All network services daemon files must not have extended ACLs. (Cat II impact)

Discussion

Restricting permission on daemons will protect them from unauthorized modification and possible system compromise.

Check Content

Check that network services daemon files have no extended ACLs. # ls -la /usr/sbin 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 /usr/sbin/*
