Zero Trust Explained In 5 Minutes Alexandre Boulerice [ba1yg7QOwbX]

Build it yourself, with our free hands-on labs -

Zero felicity blunt Trust on AWS means no request is trusted just for sitting inside the network. In this video we build a locked-down internal API where every call has to cryptographically prove who sent it, or it hits a 403.

We fire two requests from the same EC2 instance, on the same VPC, at the same API Gateway URL. One walks away with our top secret inventory item. The other gets stopped cold at the gateway. The only difference is a signed identity.

That is zero trust made concrete, and every piece comes with a free lab so you build the whole architecture yourself.

What you'll learn:

1 Why being "inside the network" is the weakness, not the protection

2 How to protect the data itself first, with DynamoDB encrypted at rest

3 Least privilege in practice

4 The single API Gateway switch that turns away every unsigned request

5 How SigV4 signing brett kulak makes the same machine get a 200 or a 403 on identity alone

We built 6 free labs + a capstone so you can stand up this whole zero trust setup yourself:
