How does CSP improve user safety?

What is Content Security Policy (CSP)?

Content Security Policy (CSP) is a security feature that helps prevent various types of attacks, such as Cross-Site Scripting (XSS) and data injection attacks, by controlling which resources can be loaded on a web page.

How does CSP actually improve user safety?

CSP improves user safety by allowing web developers to specify which content sources are trusted. This means that even if an attacker tries to inject malicious scripts, the browser will block them if they are not from a trusted source.

Can you give me an example of how CSP works?

Sure! For instance, if a website sets a CSP that only allows scripts from its own domain, any attempt to load a script from an external site will be blocked, thus protecting users from potential threats.

Are there any limitations to using CSP?

Yes, while CSP is powerful, it can be complex to implement correctly. Misconfigurations can lead to legitimate content being blocked, which may disrupt the user experience.
