Password Rotation Policies and SBOMs: Active Defense for the Software Supply Chain

The breach began with a single stale password, hidden deep inside a vendor’s build pipeline. By the time security teams noticed, attackers had already mapped the entire software supply chain.

Password rotation policies and Software Bill of Materials (SBOM) are not optional. Used together, they shut down two of the most common attack vectors: credential compromise and hidden dependency risk. A password rotation policy sets clear rules for how often credentials are changed, how they’re stored, and how they’re revoked. An SBOM lists every component, library, and dependency in your software, so you know exactly what’s running and where security gaps might form.

When passwords never change, attackers can sit quietly inside your infrastructure for months. When you don’t have an SBOM, you can’t prove what code is safe and what is vulnerable. These are not abstract risks. Every secret and every dependency is a live target.

A strong password rotation policy includes automated expiration, integration with secrets management tools, and alerts for non-compliant credentials. Pair that with an SBOM generated at each build and deployment. The SBOM should be machine-readable, versioned, and linked directly to your CI/CD system. This combination ensures that if a dependency is flagged as insecure, you can track its path into production in seconds and lock down any access that might be exploited.

Modern development demands visibility and control over both identity and code. Password rotation policies reduce the attack surface from compromised credentials. SBOMs reduce the attack surface from untracked or outdated components. Together, they give you active defense across the supply chain.
