What is the primary purpose of 'Field Level Security' in Dynamics 365?

The primary purpose of 'Field Level Security' in Dynamics 365 is to restrict access to specific fields based on user permissions. This feature allows organizations to control which users or teams can view or edit particular fields in a record, enhancing the overall security of sensitive information. By implementing field-level security, administrators can ensure that only authorized personnel have access to critical data, thus protecting sensitive business information while still allowing for necessary data management and reporting.

This level of control is crucial in environments where user roles and data sensitivity vary significantly, as it helps maintain compliance with regulations and company policies regarding data access. By tailoring permissions at the field level, organizations can effectively mitigate risks associated with unauthorized access and ensure that users can only interact with the data relevant to their roles.
