I don’t know if it was mentioned already but how could I check if my ports are under “attack”? OPs graphic looks really nice

Hi, to check attacks you should look at the logs. In this case auth.log. Being attacked on port 22 is not surprising neither really troublesome if you connect via key pair.
My graph was showing egress traffic, on any kind of server the traffic due to these attacks would have been invisible but on a backup server which has (hopefully) only ingress you can clearly see the volume of connections from attackers from bytes teansmitted
