🔐 Angular Security in Production: How XSS Protection, DomSanitizer, and CSRF Defenses Actually Fit Together

Short summary

Angular's built-in security model (DomSanitizer, SecurityContext) prevents XSS automatically when used correctly; most production incidents stem from developers bypassing these defaults rather than framework gaps. The article covers four sanitization contexts, when explicit trust is justified, CSRF and CSP integration, and common mistakes with complete code examples.

• •XSS prevention happens automatically through Angular's SecurityContext on all bindings and interpolations
• •Most security findings trace to bypassSecurityTrust* usage rather than framework flaws
• •Different contexts (HTML, STYLE, URL, RESOURCE_URL) require different sanitization levels
