AOS Security

AOS Security Advantages

The following table describes security advantages when you use the AOS.
Advantage
Description
No direct access to the SQL Server database.
The client configuration does not store the information that would enable it to connect to the database.
Built-in data encryption based on common standards.
For instance, Microsoft Dynamics AX encrypts the data in communications between the AOS and client tiers.
Flexible authentication.
Authentication to log in to the AOS requires user registration in Microsoft Dynamics AX plus registration in a supportive external system that provides authentication. The list of authentication systems that Microsoft Dynamics AX can interact with includes Active Directory Services and the Claims system of SharePoint. The ability of Microsoft Dynamics AX to interact with a variety of supportive external authentication systems is called flexible authentication.
Authorization.
The AOS has authority to read every Microsoft Dynamics AX table that is in the associated SQL Server database system. A table permissions framework prevents unauthorized Microsoft Dynamics AX users from accessing any table which has itsAOSAuthorization property set to a restrictive value. Access to system tables is also restricted.
The AOS also enforces authorization according to the role-based security system.

AOS Connection to SQL Server

When you install the AOS, the setup program asks for a domain account. The AOS must have a domain account that has sufficient user rights and permissions.
The AOS account must be a user in the database and must be assigned to the following database roles:
  • db_ddladmin
  • db_datareader
  • db_datawriter
In addition, the AOS user must have the following user rights and permissions to execute stored procedures in the database:
  • createserversessions
  • createusersessions

Below are few examples of Overriding commonly used Table methods: initValue(): If we create a new record from the table browser or a form the table method initValue() is executed.

Ø   So If we have 3 enum elements in SysDimension, then its corresponding array elements are stored in    dimension EDT and can be referred as Dimension[0], Dimension[1].....
