Default and Sample Security Definitions

In Microsoft Dynamics AX 2012, permissions for all application elements are
created and grouped into out-of-box, task-based roles and duties. In previous
versions, no security settings were provided by default. Administrators created
their own user groups and granted those groups access to application elements.

In previous releases, security was not defined by default. Administrators had to
create their own user groups and grant those groups access to application objects. 

In Microsoft Dynamics AX 2012, permissions for all application objects have
been grouped into task-based privileges and duties. For example, the
administrator no longer has to grant access to the Create sales order form and
all of the related application objects. Instead, the administrator can grant access
to the Maintain sales order duty, which includes all of the permissions that are
required to view, create, modify, and delete sales orders.
Sample security roles and duties also make security easier to set up. Roles and
duties are provided for every area of Microsoft Dynamics AX, and relevant
privileges are assigned to these roles and duties by default. You can use the
sample security roles and duties as they are, modify them to fit the needs of your
business, or create new security roles and duties.

NOTE: The default security roles have application access by default, but no data
restrictions are applied by default.
