Ensure sshd IgnoreRhosts is enabled

높음레벨 1자동aix

설명

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 or provide an SSH key when authenticating with SSH, rather than trusting the remote host. Audit: evaluates the effective configuration from `sshd -T` (Match blocks must be reviewed separately).
