Content Security Policy (CSP) for Backend
Understand how backend configurations can influence Content Security Policy (CSP) to mitigate client-side attacks like XSS.
Backend's Role in CSP
Welcome to Content Security Policy (CSP) for Backend! You might think CSP is just for frontend developers, but the backend plays a crucial role.
CSP is a security standard that helps prevent client-side attacks like Cross-Site Scripting (XSS). It does this by telling the browser which resources (scripts, styles, images) it's allowed to load and execute.
The backend is responsible for delivering these rules to the browser.
How Backend Delivers CSP
The backend delivers CSP rules to the browser using a special HTTP response header called Content-Security-Policy. When the browser receives this header, it enforces the rules defined within it.
This means your backend application directly controls the security policy for your frontend. Let's see how a backend might set this header.
