.NET developers integrate robust security features such as authentication, authorization, data encryption, and threat detection into applications. ASP.NET Identity, OAuth, JWT tokens, and role-based access control (RBAC) enhance authentication mechanisms. Additionally, .NET provides built-in protection against SQL injection, cross-site scripting (XSS), and cross-site request forgery (CSRF). Secure API authentication with OAuth 2.0 and HTTPS encryption ensures data integrity. Hire Dot Net Developers also conduct regular security audits, vulnerability testing, and compliance checks to safeguard applications from cyber threats. Implementing Azure Security Center and cloud-based security solutions further strengthens security measures.
