Title

The xinetd service must be disabled if no network services utilizing it are enabled. (Cat II impact)

Discussion

The xinetd service provides a dedicated listener service for some programs, which is no longer necessary for commonly-used network services. Disabling it ensures that these uncommon services are not running, and also prevents attacks against xinetd itself.
