What are the differences between CSP and other security measures?

Content Security Policy (CSP) is a security feature that helps prevent various attacks like Cross-Site Scripting (XSS) by controlling resources the user agent is allowed to load. Unlike traditional security measures, CSP focuses on whitelisting sources of content.

Can you explain how CSP works in practice?

Sure! CSP works by allowing web developers to specify which content sources are trusted. This is done through HTTP headers or meta tags, where you define policies that restrict where scripts, styles, and other resources can be loaded from.

What are some other security measures I should consider?

In addition to CSP, you might consider using HTTPS, input validation, and security headers like X-Content-Type-Options and X-Frame-Options to enhance your web application's security.

How does CSP compare to using HTTPS?

CSP and HTTPS serve different purposes. HTTPS encrypts data in transit, protecting it from eavesdropping, while CSP helps mitigate risks from malicious content by controlling what can be loaded on a webpage.
