Why do we get a high number of failed login between SSH sessions?
We have a couple of Ubuntu 16.04 server and noticed that when we create a SSH session in the morning that there were thousands of failed login attempts since the day before. Even after minutes between sessions there are already several dozen failed login attempts reported. I can confirm that nobody in our organisation did even attempt to log on to the droplet during that period.
