Key points:
Threat Increase: Attacks targeting software supply chains have sharply risen, especially in open source components.
Hardened/Distroless Images: Use minimal, security-hardened containers to cut down vulnerabilities, especially in regulated environments.
Compliance Focus: Follow NIST, STIG, FIPS, and SLSA frameworks for assured compliance and traceability.
Disconnected Readiness: Prepare infrastructure and tooling for air-gapped environments and automated compliance management.
Holistic Security: Integrate security across all stages, not just at the beginning of the development process.
