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. This option only applies to SSH Protocol Version 2. 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 . Fix: Edit the /etc/ssh/sshd_config file to set the parameter as follows: HostbasedAuthentication no [no/yes] Edit the /etc/ssh/sshd_config file to set the parameter as follows: HostbasedAuthentication no oval:org.secpod.oval:def:65995 oval:org.secpod.oval:def:87324 oval:org.secpod.oval:def:92295 oval:org.secpod.oval:def:85173 SCAP Repo OVAL Definition 2023-08-23
