TMA-AIX-4.6.3.7
Ensure sshd HostbasedAuthentication is disabled
Description
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. Host-based authentication is a method to authenticate users (rather than requiring password or key-based authentication method). Used at a system level by OpenSSH requires the file /etc/shosts.equiv to contain a list of so-called trusted hosts. Audit: evaluates the effective configuration from `sshd -T` (Match blocks must be reviewed separately).

Edit the /etc/ssh/sshd_config file to set the parameter above any Match entries as follows: HostbasedAuthentication no Re-cycle the sshd daemon to pick up the configuration changes: stopsrc -s sshd startsrc -s sshd Note: First occurrence of a option takes precedence, Match set statements withstanding.
