Did you know that over 60% of cyber attacks exploit weak or missing security headers? One of the most crucial headers to protect your website is Content Security Policy (CSP).
🔹 What is CSP?
CSP is a security feature that helps prevent Cross-Site Scripting (XSS), code injection, and data theft by controlling which scripts, styles, and resources can load on your site.
🔥 Why is CSP Important?
✅ Blocks Malicious Scripts – Stops attackers from injecting harmful JavaScript.
✅ Prevents Data Theft – Mitigates attacks that steal user credentials via phishing.
✅ Secures Third-Party Integrations – Limits external scripts to trusted sources.
✅ Reduces Attack Surface – Strengthens security beyond firewalls & SSL.
⚡ Example of a Secure CSP Header
Content-Security-Policy: default-src 'self'; script-src 'self' https://trusted-source.com; style-src 'self' 'unsafe-inline'; object-src 'none';
This setup:
🔹 Allows scripts only from your site & trusted sources
🔹 Prevents malicious inline JavaScript execution
🔹 Blocks insecure Flash & object embeds
🔍 How to Implement CSP
1️⃣ Add it to your web server headers (Apache, Nginx, etc.).
2️⃣ Use Content-Security-Policy-Report-Only to test before enforcing.
3️⃣ Continuously refine policies using CSP violation reports.
A well-implemented CSP is your first line of defense against modern web threats. Is your website protected?
