Assignment of the RACF OPERATIONS attribute to individual userids must be fully justified.

Overview

Finding ID	Version	Rule ID	IA Controls	Severity
V-294	RACF0720	SV-294r3_rule		Medium

Description
A user possessing the OPERATIONS attribute has authorization to do maintenance operations on all RACF-protected data sets, tape volumes, and DASD volumes except those where the access list specifically limits the OPERATIONS user to a lower access authority than the operation requires. Because the OPERATIONS and GROUP-OPERATIONS privileges allow widespread access they should be limited to users documented with a valid requirement. Delegation of GROUP-OPERATIONS processing to other personnel by site-defined Group Administrators is forbidden.

Fix Text (F-448r1_fix)
Review all USERIDs with the OPERATIONS attribute. Ensure documentation providing justification for access is maintained and filed with the IAO, and that unjustified access is removed. A sample command to remove the OPERATIONS attribute from a userid is shown here: ALU NOOPERATIONS To remove the Group-Operations attribute: CO GROUP() NOOPERATIONS
