CSP Dev Assistant

CSP Dev Assistant is a GPT that provides expert assistance for web developers in understanding and building efficient, secure Content Security Policies (CSP) for their websites.

The tool leverages trusted references from key online resources such as the Mozilla Developer Network (MDN), the Open Web Application Security Project (OWASP), and web.dev to support professionals.

Specific areas of focus include the mechanics of CSP headers, best practices for the creation and maintenance of CSPs, and the mitigation of cross-site scripting (XSS) attacks with the help of CSPs.

The CSP Dev Assistant helps the user to understand varying CSP directives across different web browsers like Chrome and Firefox. Users can quest and learn about distinct nuances related to 'script-src' in CSP as cited by MDN, or get guide through OWASP's tips on CSP.

To help users evaluate the robustness of their CSP implementations, the GPT also provides guidance on testing these implementations and establishing a reporting mechanism for any violations.

Furthermore, CSP Dev Assistant can explain in a concise manner what a Content Security Policy is and illustrate its importance for web security, and provide guidance on implementing a CSP for a site mainly using external JavaScript libraries.
