Best way to secure Ubuntu Droplet?

Posted March 17, 2014 10.6k views
I've read many of the tutorials found here about ways to harden an Ubuntu server installation but I still have a few questions: 1. Does the default image for Ubuntu 12.04.3 LTS used by Digital Ocean have any pre-configured security optimizations. 2. What steps can I take to secure my Ubuntu server that is running Webuzo control panel. Will any of these security precautions interfere or break Webuzo?

1. No. You are alone responsible for managing your VPS.

2. Not entirely certain of what webuzo requires to run properly, but if you configure both the firewalls and your service correctly, webuzo should run flawlessly.

A few stuff you could look into regarding securing your server:

iptables (firewall)
fail2ban (IPF)
Clamav (basically an anti-virus/rootkit software which isn't really required unless you believe to already be hacked)

But none of these will get you very far if your webapp's isn't secure.
You can configure the Security tools provided by Webuzo i.e CSF, BFD, etc.
Manage SSH access, Restrict IP, etc.

Here is a list of security tools:
