Why is implementing security rules at the entity level considered more secure?

Implementing security rules at the entity level is considered more secure because these restrictions are enforced directly at the database level. This means that any interaction with the data, whether through the Mendix application interface or other means (like direct database access), is governed by these rules. By applying security measures at this foundational layer, the system ensures that unauthorized users cannot access or manipulate sensitive information regardless of the method they use to query the database.

The effectiveness of security at the entity level comes from the fact that it serves as a first line of defense, ensuring that only permitted data can be seen or altered based on the user's permissions. This level of control helps prevent data breaches and enforces data integrity effectively.

Other options refer to aspects that do not enhance security in the same way. For instance, manually managed restrictions can introduce human error and inconsistencies, while user confirmation does not address underlying access control. Additionally, treating restrictions as optional undermines the fundamental purpose of securing data, as it may leave gaps that could be exploited.
