6.2.3. What Barriers Are in Place To Prevent Abuse of Resources
The careful organization of groups and assignment of permissions for shared resources is one of the most important things a system administrator can do to prevent resource abuse among users within an organization. In this way, those who should not have access to sensitive resources are denied access.
But no matter how your organization does things, the best guard against abuse of resources is always sustained vigilance on the part of the system administrator. Keeping your eyes open is often the only way to avoid having an unpleasant surprise waiting for you at your desk one morning.
