One particular area of protection I was hoping to get from Astaro (Novell Security Manager) was to inhibit the pervasive sshd brute force attack. Astaro is constantly getting its updates; yet, there appears to be no detection of the attack. Does anyone know if Astaro guards against this particular attack or is it too difficult to detect? My log entries show the attack interval is approximately 4 seconds spanning numerous attempts. I'd prefer a firewall solution before taking measures with the sshd configuration.
