Cloud Linux Supply Chain Guide
GuideProtecting cloud Linux instances from supply chain attacks targeting VM images, package repositories, and cloud marketplace offerings.
Key Features
Cloud Linux Supply Chain Security
Cloud instances inherit supply chain risks from VM images, marketplace offerings, and shared infrastructure.
Step 1: Build Your Own Images
Don't trust random marketplace AMIs. Build from official ISOs or use CIS Hardened Images.
Step 2: Scan Base Images
Every base image should be scanned for vulnerabilities and malware before deployment.
Step 3: Mirror Package Repositories
Run private package mirrors to control what versions are available to your instances.
Step 4: Lock Down Instance Metadata
Enforce IMDSv2 on AWS (or equivalent on other clouds) to prevent SSRF-based credential theft.
Step 5: Implement Image Signing
Sign your golden images and verify signatures before launching new instances.

Google SLSA & NIST SSDF: Emerging Software Supply Chain Security Best Practices
Tony Loehr's Linux Foundation talk connects Google's SLSA framework with NIST's Secure Software Development Framework, mapping emerging best practices to real-world implementation across 16 chapters covering supply chain attacks, the Presidential Executive Order, and SBOM adoption. It's the policy-meets-practice talk that shows how two major frameworks converge to protect cloud-native software from source to deployment.
