Image signing and verification

Image signing and verification form a key part of this defense within Software Supply Chain Security. 

Core Practices: 

1. Image Signing: Sign images with a trusted certificate before deployment. This ensures each image originates from an authorized source. 

2. Automated Verification: Configure Kubernetes to only run images that pass verification checks, blocking unauthorized content. 

By incorporating these practices, organizations can enhance the trustworthiness of their software supply chain, reducing risks associated with unverified images in Kubernetes clusters.
