How to properly secure SSH?
Hello, I logged into my server today to find out there's been 157 unsuccessful attempts to login. I installed and configured fail2ban right away (I hope jail.local is fine). (I forgot to do it...) Protocol 2 is used by default in Fedora - so that's okay. I'm not sure if I should change the SSH port though. https://www.adayinthelifeof.nl/2012/03/12/why-putting-ssh-on-another-port-than-22-is-bad-idea/ http://www.danielmiessler.com/blog/putting-ssh-another-port-good-idea Do you think it's a good idea to change it if it's done properly? If I use port-knocking it should be okay, right? Or do you think I should leave it alone? Thank you!
