How can a System Administrator protect sensitive data for a custom field?

Enabling field-level security settings is an effective way to protect sensitive data for a custom field. Field-level security determines which users can view and edit the data in a specific field, regardless of their profile or role. By configuring these settings, a System Administrator can ensure that only authorized users have access to sensitive information, while others are either restricted from viewing or editing the field altogether.

This method provides granular control over data access, ensuring compliance with privacy regulations and organizational policies. It is crucial for protecting sensitive data, as it directly impacts who can interact with that specific field based solely on their user permissions and roles, without being affected by the context of record types or page layouts.

In contrast, while utilizing record types and implementing different page layouts can aid in data organization and present different views of data based on user roles, these methods do not specifically restrict access to the data contained within custom fields. Similarly, limiting field access through permission sets can be useful, but it operates at a broader level, affecting multiple fields and might not provide the precise control that field-level security offers for individual fields.
