Field-level security in Salesforce is a critical aspect of data protection and user access management. It defines which users have permission to view and edit specific fields within an object. By configuring field-level security, administrators can ensure that sensitive information is only accessible to authorized users based on their profiles.

This capability is essential for complying with data privacy regulations and protecting sensitive data, as it allows organizations to customize the visibility of individual fields rather than just the overall records. For example, while a user may have access to a record, field-level security can hide certain fields from them based on their role or profile, thereby maintaining confidentiality around particular pieces of information.

The other options do not accurately reflect the concept of field-level security: full access to all fields would not involve restrictions and does not provide the depth of control that field-level security offers. Similarly, while the layout of fields on a page is determined by page layouts, it doesn't pertain to user security and access. Lastly, customization of field data by users does not relate directly to the security aspect but rather to the ability to modify information, which is a separate function.
