SSH .rhosts or .shosts weak authentication
| sshd-rhosts (315) |  Medium Risk |
Description:
The SSH (Secure Shell) server on this computer supports Berkeley .rhosts or .shosts style authentication. This form of authentication relies on trusted host names and is defeatable by DNS (Domain Name System) cache poisoning and IP spoofing.
Consequences:
Bypass Security
Remedy:
If SSH is already installed, disable .rhosts authentication and use only RSA and RHOSTS-RSA.
