An engineer adds a new "Forensics" tab that includes several sections for detailed artifact analysis...

According to the Cortex XSOAR Admin Guide, visibility of layout tabs is controlled byrole-based access permissions (RBAC). When customizing layouts, administrators can assign tabs, fields, and components to specific user roles. If the “Forensics” tab appears for senior analysts but not junior analysts, this indicates that the tab has been assigned only to certain roles through the “Roles” field in the layout editor.

XSOAR does not hide layout tabs due to incorrect field mappings (option A). If a field is unmapped, it simply appears empty, not invisible. Likewise, marking a tab as “read-only” (option C) still makes it visible; it only restricts editing. Display filters (option D) apply to list widgets, dashboards, and incidents—not layout tab visibility.

The documentation clearly states thata tab will not appear to a user unless their assigned role is included in the tab’s role permissions. Therefore, junior analysts cannot view the tab becausethe tab was not assigned to their role, making optionBthe correct explanation based on XSOAR’s RBAC-controlled layout behavior.
