The security in Microsoft Dynamics AX Enterprise Portal depends on the underlying technologies, such as SharePoint and Internet Information Services (IIS). There are two types of web portal users: the public user and the dynamics user. The public user allows for the viewing of products, requests for products, creation of account, and so on.

The public users have an anonymous authentication, so it is available for anyone who uses the Internet. Therefore, there is a built-in guest user account that is a part of the Enterprise Portal that's connected to Microsoft Dynamics AX components with a limited access that is necessary for the website to function in a proper manner and also for security reasons.

The dynamics users are authenticated employees, customers, and vendors. They have a complete portal to make transactions and view reports and charts, and they are referred to the security policies on Microsoft Dynamics Enterprise Portal.
