How is dealt with security on the DigitalOcean VPS?

May 16, 2014 1.2k views
Hey guys, I moved from my previous hosted to DO (not migrated yet) because, I thought, I had a lot of downtime and my servers were often out of reach. I recall, I thought so. Yesterday, I found out that my servers haven't been down at all, but because of security (too many requests via ftp / Too many open connections (TCP/SMTP/FTP) my IP was blocked for a few minutes. It feels like downtime, but instead it's just a matter of protection. While security is great, being blocked for a few minutes, up to 15 in my experience, is terribly annoying. The rather worse thing of it, is that this problem occurs about at least a few times a week. However, once again: security is great. Because of that, I'm unsure what to choose. Ease of use or just be happy there is/was at least that kind of protection. To come to the questioning part, I've got two questions: 1. What is your personal opinion about this? Would you favor this kind of security or would you be annoyed yourself because of it? 2. How would you deal with security on your own server? // It if matters: Mainly regarding Ubuntu servers, as I'm currently only using Ubuntu's. Thanks guys!

DigitalOcean does not rate limit you, so this wouldn't have happened here. If for some reason our team has to take an action on your droplet, you will receive notification. So you should never be left guessing what the issue is.

As for more general server security, I'd highly recommend installing fail2ban which prevents brute force login attacks attacks against your server. See:

And setting up additional firewall rules is usually the first thing I do on a server:

fail2ban provides a way to automatically protect virtual servers from malicious behavior. This tutorial shows you how to install Fail2Ban, copy the Configuration File, configure the fail2ban defaults, and find out how to configure the ssh defaults. This tutorial describes the required steps to set up fail2ban on Ubuntu.
