This title delves into the essential topic of software supply chain security.

Use Software Composition Analysis (SCA) Tools

SCA tools scan your dependencies for known vulnerabilities and licensing issues.

• Identify outdated or vulnerable libraries.
• Receive alerts on newly discovered CVEs.
• Track and manage open-source risks.

Popular tools: Snyk, WhiteSource, Black Duck, GitHub Dependabot

Implement Code Signing and Artifact Integrity Checks

Digitally sign code, containers, and build artifacts to prove authenticity and prevent tampering.

• Use tools like Sigstore, Cosign, and Notary v2.
• Validate integrity at deployment with checksum verification.

Adopt Zero Trust Principles in CI/CD Pipelines

Secure every step of the build and deployment process.

• Use role-based access control (RBAC) and least privilege policies.
• Isolate builds in clean environments (e.g., ephemeral runners).
• Scan containers and Infrastructure-as-Code (IaC) templates.

Maintain a Software Bill of Materials (SBOM)

An SBOM is a detailed list of all components in your application.

• Enables transparency and traceability.
• Required for compliance with U.S. Executive Order 14028 and other regulations.
• Tools: CycloneDX, SPDX, Anchore, Syft

Monitor Developer and Third-Party Access

Control and audit access to source code and build systems.

• Enable multi-factor authentication (MFA) for all development accounts.
• Review permissions regularly for GitHub, GitLab, and other platforms.
• Vet third-party vendors and contributors.
