Is something needs to be done to secure linux server after installing vpn on it?
 

Hi,

I am newbie to Linux. I bought a vps server and installed openvpn server on it. It works fine. But what I worry is, every article I read about how to setup vpn server only shows how to install&configure vpn but doesn't mention about the server security.

I have only few firewall rules about how to transfer traffic to my laptop successfuly. Because I haven't installed anything other than vpn, do you think someone can access to server except ssh login? I have no firewall rules other than forwarding rules. On windows I have tons of security programs and that makes me uneasy on linux.

Could you please give me advice?

My advice would be to just use it, Linux does not have all of the security issues windows has. You could add a few items to your ip tables if you wish. I have used Linux for over a dozen years with no firewall or virus checker and have never had a problem of any kind. I just upgraded Linux for a friend that had used it for 10 years on the same install with no problems, the only reason for the upgrade was flash was outdated for version 1 firefox. She had over 1100 bookmarks so she was a heavy user.
