Welcome to this week’s edition of the DevOps Bulletin!

Ever wondered about the vulnerabilities lurking in your Terraform state? Find out how attackers could potentially take over your CI/CD pipeline with just a few edits.

Curious about enhancing security between GCP and AWS? Learn the ins and outs of using short-lived credentials to safeguard your cloud resources.

And if you're venturing into Kubernetes Hardening, we've got you covered with a step-by-step guide on deploying a hardened Kubernetes cluster in AWS using kOps.

But that's just the tip of the iceberg! We'll also explore topics like centralizing security for AWS multi-account setups, migrating from Serverless Framework to AWS CDK, and much more ❤️
