Clearance Levels: Manage File Permissions
Control who can access, modify, or execute classified files
Objectives cleared0 / 2
+15 XP per step · +75 XP for completing the quest
Every file in the Federation system has a clearance level — who can read it (r), who can write to it (w), and who can execute it (x). These are Linux permissions. As a senior pilot-operator, you must know how to read these clearances and change them when ordered.
Primary Objective
Use ls -l to read permissions and chmod to change them.
