Securing your python applications and network using Zero Trust Security

Srijan R Shetty (~srijanshetty)




Securing applications is hard.

AWS Security Groups, Firewalls, iptables don't make it any easier.

It's common to hear terms like Zero Trust, Mesh VPNs, SD-WAN being thrown around in the context of modern DevOps but it's hard to keep upto speed with them or even start using them in the wild due to the lack of resources.

Fret not, in this talk we'll cover Zero Trust from first principles and go through examples of creating secure by default production environments using Fast API. We'll understand what the noise about mesh VPNs and why DevOps can't stop raving about them. In particular we would look at TailScale which is an excellent way to get started on the journey of secure, encrypted production environments with fine grained access controls.

Layout of the Talk - Initial Setup of TailScale (5 minutes) - Encrypted secure connections to redis from python (3 minutes) - ACLs & port mappings for your team (3 minutes) - Secure SSH over mesh VPNs (2 minutes) - Hosting Fast API securely with nginx, self hosted certificates (7 minutes) - Share local Fast API using TailScale funnel (5 minutes) - Securing connections to Postgres with pgproxy (Optional)


A basic understanding of python and know how of how to use a terminal to run commands.
