Self-invoking. Learn JavaScript!

This type of JavaScript function is known as self-invoking or immediately-invoked function expression (IIFE). It is a function that is defined and executed at the same time, without being assigned to a variable or being called by another function. It is often used to create a local scope for variables and avoid polluting the global namespace.

Restricted caller access is enabled through a platform capability delivered as a plugin. The direct method to activate it is to activate the Scoped Application Restricted Caller Access plugin, which turns on the restricted caller access behavior and supporting controls for cross-scope interactions. Additionally, certain ServiceNow applications, such as HR Service Delivery or Security Incident Response, may require this capability and, when requested/installed, can drive activation of the necessary supporting features as part of meeting that application’s security model. That aligns to option B as an activation path tied to obtaining the applications that depend on the feature. Option A is not an activation method, it is a blanket security stance that does not represent how the feature is turned on in the platform. Option D is different functionality: Cross-Scope Access Override is a specific override mechanism for cross-scope calls and does not itself activate restricted caller access. The verified activation methods are the plugin activation and obtaining the applications that require it.

Access Control scripts are server-side scripts that run when an Access Control rule is evaluated. They can use the gs and current objects to access the GlideSystem and GlideRecord methods, respectively. Some of the useful methods in Access Control scripts are:

gs.hasRole() - This method checks if the current user has a specified role. It returns true if the user has the role, and false otherwise. For example, gs.hasRole(‘admin’) will return true if the user is an administrator, and false otherwise.

current.isNewRecord() - This method checks if the current record is a new record that has not been inserted into the database yet. It returns true if the record is new, and false otherwise. For example, current.isNewRecord() will return true if the record is being created, and false if the record is being updated or deleted.

The methods g_user.hasRole() and current.isNew() are not part of the server-side scripting API. They are part of the client-side scripting API, which is used in Client Scripts and UI Policies. They cannot be used in Access Control scripts.
