Angular Security Best Practices 🛡️

1. Input Validation & Sanitization

Always sanitize user inputs to prevent XSS (Cross-Site Scripting) attacks. Use Angular's built-in sanitization tags like <div [innerHTML]="userInput"> or bypassSecurityTrust() for trusted content.

2. Secure Data Binding

Avoid binding untrusted data directly. Use textContent or safe pipes for safer rendering.

⚠️ [Check Angular's data binding security docs](/en/handbooks/angular/data_binding_security)

3. HTTP Security Headers

Set proper headers like Content-Security-Policy, X-Content-Type-Options, and X-Frame-Options to mitigate risks.

4. Dependency Management

Regularly update third-party libraries to patch vulnerabilities. Use tools like npm audit or ng update.

5. Authentication & Authorization

Implement robust auth mechanisms (OAuth2, JWT) and use Angular's @angular/fire or @auth0/angular-jwt for secure handling.

6. Avoid Common Vulnerabilities

Prevent CSRF (Cross-Site Request Forgery) by using anti-CSRF tokens. Secure your app against IDOR (Insecure Direct Object Reference) and API leakage.

7. Secure Development Environment

Use environment variables for secrets and enable strict mode in tsconfig.json to catch potential issues.
