Secure Dependency Management

Pin dependency versions, monitor for CVEs, use lock files, and automate SCA in CI pipelines.

Why Dependencies Are a Risk

Modern applications import hundreds of third-party packages. Each dependency — and its transitive dependencies — extends your attack surface. A vulnerability in a popular library (like Log4Shell in Log4j) can expose thousands of applications simultaneously.

Lock Files and Version Pinning

Lock files (package-lock.json, yarn.lock, Pipfile.lock) pin every dependency to an exact version including transitive dependencies. Commit lock files to version control. This ensures reproducible builds and prevents accidental version upgrades that introduce vulnerabilities.
