• Cross-Site Request Forgery (CSRF)

  1. Token Verification.
  2. Idempotent GETs.
  3. HttpReferrer Validation.

• Over-Posting

  1. Use the Bind attribute to explicitly whitelist or blacklist fields.

ASP.NET MVC gives you the tools you need to keep your website secure, but it’s up to you to apply them wisely.

Plenty of great resources are available both in the Microsoft web development sphere and in the Internet security world at large.

Below is the list of resources to get you started:

• Microsoft Code Analysis Tool .NET (CAT.NET)

  1. Idempotent GETs.

  2. AntiXSS

  3. Microsoft Information SecurityTeam (makers of AntiXSS and CAT.NET)

  4. Open Web Application Security Project (OWASP)
