What if someone replaces your Docker image with a malicious one... and your production pipeline deploys it without noticing?

In this hands-on lab of the AI-Driven DevSecOps Masterclass, you'll learn how enterprise companies protect their software supply chain using Sigstore Cosign. Instead of trusting container images blindly, you'll digitally sign and verify them before deployment—exactly how modern DevSecOps teams secure production pipelines.

In This Practical You'll Learn
Install Sigstore Cosign on Ubuntu Linux
Build a Docker Image
Generate Public & Private Signing Keys
Push Images to Docker Hub
Digitally Sign Docker Images
Verify Image Signatures
Understand Image Integrity & Authenticity
Prevent Tampered Images from Reaching Production
Real-World Software Supply Chain Security Workflow

This practical is essential for anyone learning DevSecOps, Docker Security, Kubernetes Security, Cloud Security, Secure CI/CD, Container Security, or Software Supply Chain Security.

What You'll Achieve: By the end of this video, you'll know how to implement the enterprise workflow:
Build → Sign → Verify → Deploy
...using the industry-standard tool Sigstore Cosign.
