I know the best thing is the change the SSH port, and I normally do that on every server. Still, I have a couple of servers that I need to have 22 open on. I have on thees servers set AllowUsers root@5.xxx.xxx.93. only using the IP at home, and a private VPN service.
Can ha hacker get access via port 22 so long he is not on my homenetwork or using my VPN?
