The OWASP Cheat Sheet Series was created to provide a concise collection of high value information on specific application security topics.
The OWASP Cheat Sheet Series is a collection of concise, practical security guidance on specific application security topics, created by the Open Worldwide Application Security Project and designed for developers rather than security experts. The project is maintained by project leaders Jim Manico, Jakub Maćkowski, and Gabriel Corona, along with a core team, and content is written in Markdown and built into a static website using Python. The repository enforces strict contribution standards through automated checks for citation quality, scope, correctness, and proper sourcing from authoritative references like RFCs, NIST, official documentation, and peer-reviewed research, with mandatory disclosure of any AI tool usage in pull requests.
