CSP (Content Security Policy) is a security feature that helps protect websites from various types of attacks, including cross-site scripting (XSS) and data injection attacks. CSP security headers are a set of directives that instruct the browser on how to handle content on a website. In this article, we will provide a comprehensive cheatsheet for CSP security headers.
Understanding CSP Security Headers
CSP security headers are a set of directives that instruct the browser on how to handle content on a website. These headers are added to the HTTP response of a website and provide a layer of security against various types of attacks. CSP headers can be used to restrict the types of content that can be loaded on a website, such as scripts, stylesheets, and images. They can also be used to prevent inline scripts and styles, which are a common source of XSS attacks.
A Comprehensive Cheatsheet for CSP Security Headers
Here is a comprehensive cheatsheet for CSP security headers:
- default-src: This directive specifies the default source for content that is not explicitly defined in other directives.
- script-src: This directive specifies the sources from which scripts can be loaded.
- style-src: This directive specifies the sources from which stylesheets can be loaded.
- img-src: This directive specifies the sources from which images can be loaded.
- connect-src: This directive specifies the sources from which the browser can make network requests.
- font-src: This directive specifies the sources from which fonts can be loaded.
- object-src: This directive specifies the sources from which plugins can be loaded.
- media-src: This directive specifies the sources from which media files can be loaded.
- frame-src: This directive specifies the sources from which frames can be loaded.
- sandbox: This directive specifies whether the content should be loaded in a sandboxed environment.
- report-uri: This directive specifies the URL to which violation reports should be sent.
By using these directives, website owners can customize the security policy of their website and protect against various types of attacks.
CSP security headers are an essential security feature that can help protect websites from various types of attacks. By using the comprehensive cheatsheet provided in this article, website owners can customize the security policy of their website and ensure that their users are protected from malicious content.
