Secure Linux/Unix system that runs OpenSSH

I came across invaluable article on how to make Linux system that runs OpenSSH server to be even more secure. It’s written by 17-year-old (!!!) Peter Upfold from FOSSwire and covers the following simple steps:

  • fosswire logoDisable SSH protocol 1
  • Enable key-based logins
  • Don’t enable password-based logins
  • Don’t run on port 22
  • No remote root logins

I found these tips invaluable and sire that there is no doubt SSH-2 protocol remains the most common and safe method to access remote Linux or Unix system. The article is freely available here.
