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.
