What does implementing field-level security ensure in Dynamics 365?

Implementing field-level security in Dynamics 365 ensures that access to sensitive data is restricted based on user roles. This means that administrators can define which users or teams have access to certain fields, thereby safeguarding confidential information within the system. By controlling visibility and editability of specific fields in records, organizations can enforce security measures that align with their data governance policies. This helps maintain compliance and protects sensitive data from unauthorized access, allowing only the designated roles to view or modify those fields.

The other choices pertain to different aspects of data management and security. For instance, restricting visibility of records to specific users or teams deals more with record-level security than field-level security. Encryption at the field level refers to a separate security measure that focuses on protecting data through cryptographic techniques rather than role-based access. Lastly, optimization of data storage for retrieval is related to performance considerations in database management rather than security measures, emphasizing efficiency rather than access control.
