You shoulddismissa code scanning alert if the flagged code isnot a true security concern, such as:

Code in test files

Code paths that are unreachable or safe by design

False positives from the scanner

Fixing the code would automaticallyresolvethe alert — not dismiss it. Dismissing is for valid exceptions or noise reduction.

For compiled languages, CodeQL performs extraction bymonitoring the normal build process. This means it watches your usual build commands (like make, javac, or dotnet build) and extracts the relevant data from the actual build steps being executed. CodeQL uses this information to construct a semantic database of the application.

This approach ensures that CodeQL captures a precise, real-world representation of the code and its behavior as it is compiled, including platform-specific configurations or conditional logic used during build.

Comprehensive and Detailed Explanation:

Push protection for secret scanning custom patterns is an opt-in feature. This means that for each custom pattern defined in a repository, maintainers can choose to enable or disable push protectionindividually. This provides flexibility, allowing teams to enforce push protection on sensitive patterns while leaving it disabled for others.​

Comprehensive and Detailed Explanation:

When GitHub identifies a vulnerable dependency in a repository with Dependabot alerts enabled, it performs the following actions:​

Generates a Dependabot alert: The alert is displayed on the repository's Security tab, providing details about the vulnerability and affected dependency.​

Notifies repository maintainers: By default, GitHub notifies users with write, maintain, or admin permissions about new Dependabot alerts.​

GitHub Docs

These actions ensure that responsible parties are informed promptly to address the vulnerability.​
