GitHub is a web-based version control system that allows developers to store and manage code and other files, and to collaborate on projects. GitHub is one of the most popular version control systems for computer code, and includes helpful collaboration features such as project wikis, bug tracking, and feature requests for every project. GitHub's popularity and ease-of-use mean that repositories often include sensitive information, sometimes more than is intended. It's common for developer secrets and sensitive log files to inadvertently end up on GitHub, introducing high risk of a data breach or compliance violations.
