Content Security Policy (CSP) Explained | iProgrammer Solutions

Cross-Site Scripting (XSS) is one of the most dangerous and common vulnerabilities in modern web applications — even in React.
In Part 1 of our CSP (Content Security Policy) series, we explore how you can prevent malicious scripts and secure your frontend with a static-friendly CSP setup using meta tags in a React + Vite environment.
Whether you’re building a startup MVP or scaling a web platform, implementing CSP isn't optional anymore — it's your first real defense against XSS attacks.

In This Video, You’ll Learn:
1. What is Content Security Policy (CSP) — explained in simple, developer-friendly terms
2. How attackers exploit vulnerabilities using one script tag
3. How to implement CSP without a server using meta tags (ideal for React + Vite)
4. Why CSP is essential — even if you’re not handling sensitive financial data
