OWASP Cheat Sheet Series is a reference collection of application security best practices organized as concise guides on specific topics.
The project addresses the need for developers to quickly access reliable security guidance when building applications. It provides focused cheat sheets covering individual security domains, allowing builders to reference established practices without extensive research. The content is maintained as markdown source files and published through an official website where users can read and reference the material.
Developers should use this resource when they need to understand security best practices for a particular application concern, whether during design, development, or code review. The project suits teams of any size looking for authoritative OWASP-backed guidance. The material is intended for reference through the official website rather than as embedded documentation in external sources.
The project maintains an active contribution process with a documented guide for adding new cheat sheets and improving existing content. The team actively invites contributors and encourages participation through multiple channels including a dedicated Slack community. The project supports local development and testing through Python-based build tooling, with options for both direct execution and containerized builds using Docker or Podman. Automated linting checks help maintain markdown quality and consistent terminology across the collection.
