Check Text ( C-30069r490126_chk )
Check the TCP wrappers configuration files to determine if SSHD is configured to use TCP wrappers. Procedure: # egrep '^[^#:]*(ALL|sshd)' /etc/hosts.deny # egrep '^[^#:]*(ALL|sshd)' /etc/hosts.allow If neither of the hosts.deny or hosts.allow files exist, this is a finding. If no entries are returned, the TCP wrappers are not configured for SSHD, this is a finding.

Fix Text (F-30057r490127_fix)
Add appropriate IP restrictions for SSH to the /etc/hosts.deny and/or /etc/hosts.allow files.
