Hello, Hope you are doing well!
I am a senior Linux Administrator with 15 years experience.
I have worked on all linux distros and I suggest ubuntu 18 to make it more secure.
I can harden the server to make it bullet proof.
Looking forward to discuss further.
Best Regards
Sudhanva
Hello, I am a very experienced Linux Administrator.
I have my own Server Hosting Company in Germany. I can setup Ubuntu or Debian with a Firewall and I can make it very secure. I'll use SSH Key Based Authentification and Iptables to secure the Network.
Let me know If you interested.
