GEN005500 - The SSH daemon must be configured to only use the SSHv2 protocol.

Information

SSHv1 is not a DoD-approved protocol and has many well-known vulnerability exploits. Exploits of the SSH daemon could provide immediate root access to the system.

Solution

Edit the configuration file and modify the Protocol line.

Protocol 2

Restart sshd:

/sbin/init.d/secsh stop
/sbin/init.d/secsh start
