Whether you are running on a public or a private cloud provider, this talk aims to help you secure your cloud based deployment, by using a simple step-by-step guide that involves using open source tools. You will be able to understand and implement a security framework for your own cloud deployment.

This talk outlines a 12-step guide consisting of the following steps:

  1. Knowing your shared responsibility
  2. Protecting your network
  3. Protecting your cloud machine images
  4. Protecting your data at rest
  5. Protecting your data in transit
  6. Protecting and patching your instances
  7. Protecting access to your instances
  8. Protecting your applications
  9. Auditing and monitoring your cloud
  10. Validating your protection
  11. Automating everything
  12. Updating your security policy

Open Source tools and technologies covered:

  • PfSense, Openswan, OpenVPN
  • SELinux, App Armor, Dm-crypt
  • Nginx, ModSecurity
  • Samba/Winbind, OpenLDAP
  • Logstash, Nagios, Ganglia
  • Metasploit, Nessus

We will be going over each step in detail, so attendees can understand the importance of underlying security domains and learn how to go about implementing them using open source solutions alone. I will also be sharing my personal experiences and best practices when it comes to implementing a security framework for the cloud using open source tools and technologies.
