AWS Security Token Service: A Practical Tutorial

In this video, I walk you through how to configure the AWS Security Token Service (STS) and how to leverage it with a simple C# application to securely authorize a call to an AWS Lambda service.

I delve into the mechanics of AWS STS, demonstrating how to set it up and use it effectively to manage temporary, limited-privilege credentials for your applications. This approach reduces the risk associated with long-term credentials and enhances the security of your AWS environment.

The demo includes:

* Creating IAM roles and policies
* Configuring trust relationships
* Generating temporary security credentials with AWS STS
* Using these credentials to invoke a Lambda function securely

This tutorial is perfect for software developers, system administrators, and anyone interested in improving their AWS security practices.

As a quick reminder, always treat AWS Access Keys as you would your password: never share or expose them.

User -> policy -> role -> policy -> resource ... phew!

Seriously, though, this is very helpful. I like the code demo at the end.

Hey. Nice Explaination. I have a question. I am the admin user in the aws account. I don't have any access key and secret key. I want to access s3 using temporary credentials. is it possible?

I saw that you gave 'AssumeRole' at 3:28 with Principal as anyone in the AWS Account while creating the role and then you created a policy "StsDemoAssumeRolePolicy" which you then added to that specific user. Is it redundant and unnecessary?
