5.1.11 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 above any Include entry as follows:

IgnoreRhosts yes

Note: First occurrence of a option takes precedence. If Include locations are enabled, used, and order of precedence is understood in your environment, the entry may be created in a file in Include location.
