title: parameter tampering for dropdownlist - ASP.NET
body: <p>I have a question, if I have set the following properties in my web.config</p>
  
  <p><code>viewStateEncryptionMode="Always" enableViewStateMac="true"</code></p>
  
  <p>Will it be still possible to tamper values of controls on my web form?
  For e.g if I have a dropdown with 3 possible values e.g. "IND", "AU", "ML" can someone still tamper this dropdown and send junk data like <code>$%^</code>?</p>
