Service Hardening

Exposed services should be hardened according to your security needs and according to what your deployed environment will allow. There is no “One size fits all” solution. If you have questions or concerns ad have a support contract with iXsystems; contact your support representative. An example of services that may warrant hardening would be: nginx, ntp, openipmi, rpcbind, ssh, winbind, wsdd, etc
