There's no black and white answer to that. On a scale of 1 to 10 you might want to assign numbers as follows: 1 = unsafe 3 = password authentication enabled 6 = key based authentication only 7 = allowing only certain IP address to access 10 = no access allowed to anyone Some people are perfectly comfortable using strong passwords and will consider anything over a '2' to be "safe". Others would only consider "safe" to be something at '7' or better and I'm certain you'll hear that '10' is the only sure defense. Regards, Mike Klinke
