{Updated} Linux server security checklist. #sysadmin 

Posted by jpluimers on 2019/03/11

Most tips are OK, but:

  3. I think ipv6 is OK, but like ipv4 needs to be firewalled
  4. Be really careful with fail2ban and similar tools: they are easy ways to lock yourself out as well, for instance by someone doing a nice (D)DoS on you.

Luckily, Wikipedia has the answer File:Ps-2-ports.jpg – Wikipedia :

Color Description
Purple Keyboard
Green Mouse
