Beschreibung

Audit: automated read-only check derived from the CIS audit procedure; it prints "compliant" when the control is met.

Ensure that all exports defined in /etc/exports have explicit client access options which clearly define the host or hosts allowed access: Review the content of /etc/exports and that all exports have explicit access lists: showmount -e | grep "(everyone)" Ensure that each NFS export has an explicit access line, for example, modify: /export/repo (everyone) to: /export/repo x071 The option -c is used to specify clients permitted access: chnfsexp -d /export/repo -c x071
