*Service

Service authority (*SERVICE) provides the user with the ability to change system hardware and disk configurations, to sniff network traffic, to put programs into debug mode (troubleshooting), and to see their internal workings.  The system services tools include the ability to trace system functions and to patch and alter user-written and IBM-delivered programs on disk.  It also allows users to turn RAID parity on and off and to remove disk drives from the system.  The number of users with this powerful authority should be tightly limited.
