CSP stands for Content Security Policy. It's a security feature implemented in web browsers that helps protect websites from malicious attacks, specifically those that try to inject unauthorized code into a trusted website. 

Here's a breakdown of how CSP works:

Website administrators define a policy: 

They specify which resources, like scripts and images, are allowed to load on their website and from which sources. This is done through a special HTTP header or a meta tag.

Browser enforces the policy: 

When you visit a website with a CSP, your web browser checks the policy to see if the loaded resources are authorized.

Unauthorized resources are blocked: 

If a resource attempts to load from a source not allowed by the policy, the browser will block it. This helps prevent malicious code from being injected and executed on the website.

CSP is particularly effective in mitigating:

Cross-site scripting (XSS) attacks: 

These attacks inject malicious scripts into a website that can steal data, redirect users to phishing sites, or deface the website.

Clickjacking attacks: 

These attacks trick users into clicking on something unintended, like a hidden button.

By implementing CSP, website owners can significantly improve the security of their websites and protect their users from online threats.
