5.2.8 Ensure SSH HostbasedAuthentication is disabled

Warning! Audit Deprecated

This audit has been deprecated and will be removed in a future update.

View Next Audit Version

Information

The HostbasedAuthentication parameter specifies if authentication is allowed through trusted hosts via the user of .rhosts, or /etc/hosts.equiv, along with successful public key client host authentication.

Rationale:

Even though the .rhosts files are ineffective if support is disabled in /etc/pam.conf, disabling the ability to use .rhosts files in SSH provides an additional layer of protection.

Solution

Edit the /etc/ssh/sshd_config file to set the parameter as follows:

HostbasedAuthentication no

Default Value:

HostbasedAuthentication no
