How to Securely Handle User Sessions and Cookies in ASP.NET Core?

Question

I am developing a web application using ASP.NET Core and need to manage user sessions and cookies securely. Can anyone provide recommendations or best practices for securely handling user sessions and cookies in ASP.NET Core?

Answer 1

Use ASP.NET Core’s built-in session and cookie middleware. Always store session data securely on the server side. Encrypt cookies using Data Protection API. Set the Secure and HttpOnly flags for cookies. Implement CSRF protection using anti-forgery tokens. Use HTTPS to protect data in transit. Regularly rotate session and encryption keys and consider using a secure token service for identity management.
