4.2.11 Ensure sshd IgnoreRhosts is enabled

Information

The IgnoreRhosts parameter specifies that .rhosts and .shosts files will not be used in RhostsRSAAuthentication or HostbasedAuthentication.

Setting this parameter forces users to enter a password when authenticating with SSH.

Solution

Edit the /etc/ssh/sshd_config file to set the IgnoreRhosts parameter to yes :

IgnoreRhosts yes

Note: First occurrence of a option takes precedence.
