Cyber threats are on the rise, and web applications are a prime target. If you’re building with Angular, security isn’t optional—it’s a must!

But are you following the best practices to safeguard your app from attacks like XSS, CSRF, and data breaches?

Let’s break it down.

*Common Security Threats in Angular Apps *

🔹 Cross-Site Scripting (XSS): Hackers inject malicious scripts into your app.

🔹 Cross-Site Request Forgery (CSRF): Unauthorized actions are performed on behalf of users.

🔹 Injection Attacks: Poorly handled inputs can compromise databases and APIs.

Sounds scary? Don't worry—Angular has built-in features to help, and with the right strategies, you can build a rock-solid app!

✅ Must-Follow Angular Security Best Practices

🔒 1. Use Angular’s Built-in Security Features

Sanitize user input with Angular’s DomSanitizer to prevent XSS.

Use HttpClient for secure API requests instead of direct JavaScript calls.

🔑 2. Enable Content Security Policy (CSP)

CSP restricts what scripts can be executed, blocking unauthorized scripts before they load.

🛡 3. Implement Proper Authentication & Authorization

Use OAuth, JWT, or session-based authentication.

Protect routes with route guards (CanActivate, CanDeactivate).

📜 4. Prevent CSRF Attacks

Use Angular’s built-in CSRF token mechanism to prevent unauthorized requests.

🕵️‍♂️ 5. Avoid Using innerHTML & Direct DOM Manipulation

NEVER trust user inputs. Using innerHTML improperly can open your app to XSS attacks.

📌 6. Secure API Endpoints & Encrypt Sensitive Data

Always validate inputs on the server side, not just the client side.

Use HTTPS and encrypt sensitive data in storage and transit.

💡 Pro Tip: Keep Angular and its dependencies updated! Security patches are crucial to staying ahead of new threats.
