Security headers quick reference  | Articles  | web.dev
Before diving into security headers, learn about known threats on the web and why you'd want to use these security headers. Protect your site from injection vulnerabilities Injection vulnerabilities arise when untrusted data processed by your application can affect its behavior and, commonly, lead to the execution of attacker-controlled scripts. The most common vulnerability caused by injection bu
Mitigate cross-site scripting (XSS) with a strict Content Security Policy (CSP)  | Articles  | web.dev
Cross-site scripting (XSS), the ability to inject malicious scripts into a web app, has been one of the biggest web security vulnerabilities for over a decade. Content Security Policy (CSP) is an added layer of security that helps to mitigate XSS. To configure a CSP, add the Content-Security-Policy HTTP header to a web page and set values that control what resources the user agent can load for tha
Introduction - Content Security Policy
This documentation is outdated and available for historical reasons only. To learn how to enable strict Content Security Policy in your application, visit web.dev/strict-csp. Content Security Policy is a mechanism designed to make applications more secure against common web vulnerabilities, particularly cross-site scripting. It is enabled by setting the Content-Security-Policy HTTP response header

Introduction to Feature Policy  | Blog  | Chrome for Developers
Summary Feature Policy allows web developers to selectively enable, disable, and modify the behavior of certain APIs and web features in the browser. It's like CSP but instead of controlling security, it controls features! The feature policies themselves are little opt-in agreements between developer and browser that can help foster our goals of building (and maintaining) high quality web apps. In

CSP Evaluator
CSP Evaluator allows developers and security experts to check if a Content Security Policy (CSP) serves as a strong mitigation against cross-site scripting attacks. It assists with the process of reviewing CSP policies, which is usually a manual task, and helps identify subtle CSP bypasses which undermine the value of a policy. CSP Evaluator checks are based on a large-scale study and are aimed to
Fixing mixed content  | Articles  | web.dev
Supporting HTTPS for your website is an important step to protecting your site and your users from attack, but mixed content can render that protection useless. Increasingly insecure mixed content will be blocked by browsers, as explained in What is mixed content? In this guide we will demonstrate techniques and tools for fixing existing mixed content issues and preventing new ones from happening.
