About code scanning with CodeQL

You can use CodeQL to identify vulnerabilities and errors in your code. The results are shown as code scanning alerts in GitHub.

Code scanning está disponible para repositorios que son propiedad de una organización en GitHub Enterprise Server. Esta característica requiere una licencia para la GitHub Advanced Security. Para más información, consulte "Acerca de GitHub Advanced Security".

Note: Your site administrator must enable code scanning for your GitHub Enterprise Server instance before you can use this feature. For more information, see "Configuring code scanning for your appliance."

About code scanning with CodeQL

CodeQL es el motor de análisis de código que desarrolló GitHub para automatizar las verificaciones de seguridad. Puedes analizar tu código utilizando CodeQL y mostrando los resultados como alertas del code scanning.

There are two main ways to use CodeQL analysis for code scanning:

On GitHub Enterprise Server 3.4, the CodeQL action uses CodeQL CLI version 2.7.6 by default. We recommend that you use the same version of the CodeQL CLI if you run analysis in an external CI system.

About CodeQL

CodeQL treats code like data, allowing you to find potential vulnerabilities in your code with greater confidence than traditional static analyzers.

  1. You generate a CodeQL database to represent your codebase.
  2. Then you run CodeQL queries on that database to identify problems in the codebase.
  3. The query results are shown as code scanning alerts in GitHub Enterprise Server when you use CodeQL with code scanning.

CodeQL supports both compiled and interpreted languages, and can find vulnerabilities and errors in code that's written in the supported languages.

  • C/C++
  • C#
  • Go
  • Java
  • JavaScript/TypeScript
  • Python
  • Ruby

Note: CodeQL analysis for Ruby is currently in beta. During the beta, analysis of Ruby will be less comprehensive than CodeQL analysis of other languages.

For more information, see the documentation on the CodeQL website: "Supported languages and frameworks."

About CodeQL queries

GitHub experts, security researchers, and community contributors write and maintain the default CodeQL queries used for code scanning. The queries are regularly updated to improve analysis and reduce any false positive results. The queries are open source, so you can view and contribute to the queries in the github/codeql repository. For more information, see CodeQL on the CodeQL website. You can also write your own queries. For more information, see "About CodeQL queries" in the CodeQL documentation.

You can run additional queries as part of your code scanning analysis. The queries you want to run must belong to a QL pack in a repository. Queries must only depend on the standard libraries (that is, the libraries referenced by an import LANGUAGE statement in your query), or libraries in the same QL pack as the query.
