I created a droplet 2 months ago and I did the basic things like configuring the firewall, setup ssh to only accept public key auth and stuff. Last night I was inspecting the logs located at /var/log/auth.log and /var/log/ufw.log and I noticed that there are a lot of IPs trying to access telnet, ssh (using brute force with random login names) and there are also some attempt to connect to some random TCP ports.
Should I be worried? Is this “normal” ?
Btw: My firewall is configure to drop all incoming packets (except ssh).
