I see this whenever I log in into my AWS EC2 Linux server using the ssh command:
Last failed login: Tue Dec 17 07:57:30 UTC 2019 from 188.8.131.52 on ssh:notty
There were 525 failed login attempts since the last successful login.
Last login: Fri Nov 29 17:33:58 2019 from 184.108.40.206
How can I stop these hacking and login attempts?
