To detect and blockvulnerable dependencies before merge, developers should use theDependency Review GitHub Actionin their pull request workflows. It scans all proposed dependency changes and flags any packages with known vulnerabilities.

This is apreventative measureduring development, unlike Dependabot, which reactsafter the fact.

Dependabot builds a dependency graph by analyzing package manifests and lockfiles in your repository. This graph includes both direct and transitive dependencies. It then compares this graph against the GitHub Advisory Database, which includes curated, security-reviewed advisories.

This method provides a comprehensive and automated way to discover all known vulnerabilities across your dependency tree.

To create or modify acode scanning workflow file(typically under .github/workflows/codeql-analysis.yml), you must haveWriteaccess to the repository.

Write permission allows you to commit the workflow file, which is required to run or configure code scanning using GitHub Actions.

The best proactive control ispush protection. It scans for secretsduring a git pushand blocks the commitbeforeit enters the repository.

Other options (like CODEOWNERS or security managers) help with oversight but do not prevent secret leaks.

Making a repo public would increase the risk, not reduce it.

All results from CodeQL analysis appear under therepository’s code scanning alertstab. This section is part of theSecuritytab and provides a list of all current, fixed, and dismissed alerts found by CodeQL.

A CodeQL database is used internally during scanning but does not display results. Query packs contain rules, not results. Security advisories are for published vulnerabilities, not per-repo findings.

Dependency reviewruns as part of a pull request and showswhich dependencies are being added, removed, or changed— andhighlights vulnerabilitiesassociated with any added packages.

It works in real-time and is specifically designed for use during pull request workflows.

Secret scanning is a feature provided by GitHub that scans the contents of your GitHub repositories for known types of secrets, such as API keys and tokens. It operates within the GitHub environment and does not scan external systems, services, or repositories outside of GitHub. Its primary function is to prevent the accidental exposure of sensitive information within your GitHub-hosted code.​

Comprehensive and Detailed Explanation:

Before defining a custom pattern for secret scanning in a repository, you must enable secretscanning for that repository. Secret scanning must be active to utilize custom patterns, which allow you to define specific formats (using regular expressions) for secrets unique to your organization.​

Once secret scanning is enabled, you can add custom patterns to detect and prevent the exposure of sensitive information tailored to your needs.​

When using a SARIF-compatible tool within GitHub Actions, it's necessary to explicitly add a step in your workflow to upload the analysis results. This is typically done using the upload-sarif action, which takes the SARIF file generated by your tool and uploads it to GitHub for processing and display in the Security tab. Without this step, the results won't be available in GitHub's code scanning interface.​

Code scanningis a static analysis feature that examines your source code to identifysecurityvulnerabilitiesandcoding errors. It runs either on every push, pull request, or a scheduled time depending on the workflow configuration.

It doesnotautomatically contact maintainers, scan full Git history, or block pushes unless explicitly configured to do so.
