security-differential-review

Security-focused differential code review analyzes pull requests and commits to detect vulnerabilities introduced by code changes. It uses git diff and git log for context, categorizing changes by risk across Auth, Input handling, Crypto, and Configuration to compare before/after states.

When reviewing code diffs, check for removed checks, new inputs without validation, altered trust boundaries, weakened cryptography, hardcoded secrets, and insecure configurations. These vulnerabilities are identified by comparing before/after states in security-sensitive code and infrastructure-as-code changes.

Yes, diff analysis evaluates dependency and infrastructure-as-code changes for security regressions. It compares before/after states of security-sensitive components to identify altered trust boundaries, insecure configurations, and weakened cryptography introduced by the changeset.

The best way to review commits for security implications is to perform differential code review using git diff and git log. This assesses security impact across categories like Auth, Input handling, Crypto/secrets, Data access, Configuration, Dependencies, Tests, and UI/frontend to detect introduced vulnerabilities.

Differential security review works without dependencies or external components. It relies on git diff and git log to provide context, categorizing changes by risk to identify hardcoded secrets, weakened cryptography, and insecure configurations directly within the changeset analysis workflow.
