The essential setting for managing record security in relationships is Field Level Security. This setting determines which fields within a record can be accessed or modified by users based on their profiles. It allows administrators to specify access rights at a granular level, ensuring that sensitive information within a record remains protected, even if the user has access to the record itself.

Field Level Security is crucial in a relational context where one record may relate to others. For instance, in a scenario where user access to certain data needs to be narrowed down—such as financial figures or personal information—this setting ensures that only the appropriate users can view or edit specific fields, thereby maintaining the integrity and confidentiality of the data.

In contrast, while other options like Sharing Rules and Profile Settings play important roles in record visibility and overall access control, they do not control access at the field level. Field History Tracking simply monitors changes to records but does not influence security settings. Thus, for detailed management of record security specifically within the context of field accessibility, Field Level Security is the key component.
