Our goal

The OWASP Cheat Sheet Series was created to provide a concise collection of high value information on specific application security topics. These cheat sheets were created by various application security professionals who have expertise in specific topics. We hope that the OWASP Cheat Sheet Series provides you with excellent security guidance in an easy to read format.

If you have any questions about the OWASP Cheat Sheet Series, please email the project leader Jim Manico, contact us on the project's Slack channel, or on our Google Group (Slack is highly preferred over the Google Group).

The archives of the old mailing list can be consulted here.

Official website

The official website on which all the cheat sheets are hosted is .

Migration to GitHub

Project has been fully migrated to GitHub.

This page is used as the OWASP homepage of the project, all the project content is hosted on the GitHub repository and we work only from this repository, wiki is not used anymore.

The GitHub repository is used for the work on the cheat sheets and the released ones are deployed on the official website.

So, from now, only a GitHub account is needed to contribute :)

Bridge between the projects OWASP Proactive Controls/OWASP Application Security Verification Standard and OWASP Cheat Sheet Series

A work channel has been created between these 2 projects and the Cheat Sheet Series using the following process (OPC = OWASP Proactive Controls / OASVS = OWASP Application Security Verification Standard / OCS = OWASP Cheat Sheet):

  • When a Cheat Sheet is missing for a point in OPC/OASVS then the OCS will handle the missing and create one. When the Cheat Sheet is ready then the reference is added by OPC/OASVS.
  • If a Cheat Sheet exists for an OPC/OASVS point but the content do not provide the expected help then the Cheat Sheet is updated to provide the content needed/expected.

The reason of the creation of this bridge is to help the OCS/OASVS projects by providing them:

  • A consistent source for the requests regarding new Cheat Sheets.
  • Same approach about the update of the existing Cheat Sheets.
  • A usage context for the Cheat Sheet and a quick source of feedack about the quality and the efficiency of the Cheat Sheet.

It is not mandatory that a request for a new Cheat Sheet (or for an update) come only from OPC/OASVS, it is just a extra channel.

Requests from OPC/OASVS are flagged with a special label in the GitHub repository issues list in order to identify them and set them as a top level priority.
