Preventing dependency confusion requires validating source authenticity during installs by enforcing centralized path checks and fail-closed verification across all registries. This stops malicious packages from overriding internal dependencies.

Lockfile integrity checking validates that resolved dependency hashes match expected values to prevent tampering. You need it when modifying dependency graphs or lockfiles to ensure packages have not been altered in transit or compromised.

Safely handle credentials in package resolvers by routing tokens and signatures exclusively through the resolver layer rather than exposing them in workflows. This enforces fail-closed verification to block unauthenticated downloads automatically.

Yes, this approach stops typosquatting and malicious packages by validating dependency resolution, lockfile integrity, and source authenticity. It enforces policy-driven checks on downloaders to reduce exposure to untrusted package names.

The best way to enforce safe deletion controls for dependencies is to apply policy-driven guardrail requirements during changes to the dependency graph. This ensures centralized path checks and fail-closed verification block unsafe removals.

You should verify source authenticity in your supply chain whenever workflows involve signatures, tokens, or credential handling. It is specifically required during changes to dependency graphs, lockfiles, or package downloaders to prevent leaked tokens.
