On which of the following objects can you NOT set security?

The correct answer is that you cannot set security on constants. In Appian, constants are predefined values that remain fixed and do not change throughout the execution of an application. They typically hold values used across various elements in a project, such as configuration settings or default parameters for processes and interfaces.

Constants are not considered sensitive data in the same way as other objects, such as documents, processes, or custom data types (CDTs). As a result, they do not have security settings that can be adjusted to control access.

In contrast, processes can have security settings to restrict who can start, view, or manage them. Documents can also have detailed access controls to determine who can view, edit, or delete them. CDTs, while being used to encapsulate data structures, can have security settings applied to control access at the level of individual records derived from those data types.

Understanding the nature of constants and their role in Appian helps clarify why security settings are not applicable to them, distinguishing them from other components that manage sensitive or proprietary information.
