Extensible Data Security (XDS)
XDS is a powerful security feature in D365FO that allows administrators to restrict 
access to data based on security policies. These policies can be tailored to enforce 
data security at a granular level, such as by legal entity, department, or specific 
records. XDS works by applying query-based filters to data sources, ensuring that 
users only see the data they are authorized to view.

Security Model
The security model in D365FO is role-based, where permissions are assigned to roles rather than 
individual users. This simplifies security management and ensures consistency across the organization. 
The security model comprises three main components: roles, duties, and privileges.

Roles: High-level groupings that represent a user's job 
function. Examples include Sales Manager, Accountant, 
and Customer Service Representative.
Duties: Groupings of related tasks that users must 
perform to fulfill their job responsibilities. Duties are 
assigned to roles, reflecting the job's requirements.
Privileges: The most granular level of security, 
privileges define specific permissions for accessing 
individual objects, such as forms, tables, and reports.

Technical Privileges
Technical privileges in D365FO are specific permissions 
that grant users access to system functions and data. 
They define what actions a user can perform within the 
application, such as create, read, update, or delete 
(CRUD) operations on specific entities.
For instance, a privilege might allow a user to create 
sales orders but not delete them. By carefully assigning 
privileges, administrators can ensure that users have the 
necessary permissions to perform their duties without 
exposing unnecessary data or system functions. www.visualpath.in
Combining XDS and Technical Privileges
The combination of XDS and technical privileges 
provides a robust security framework. XDS restricts 
data access at a fundamental level, while technical 
privileges control what actions users can perform on 
the data. Together, they ensure comprehensive 
security, protecting sensitive information and 
maintaining data integrity.

By implementing XDS and leveraging the security model's role-based approach, 
organizations can achieve fine-grained control over data access and actions in 
D365FO, enhancing both security and compliance.
