| Description | ||||
| Unrestricted control over the IOCDS files could result in unauthorized updates and impact the configuration of the environment by allowing unauthorized access to a restricted resource. This could severely damage the integrity of the environment and the system resources. | ||||

Check Text (C-256863r958472_chk)
Using the Hardware Management Console, verify that a logical partition cannot read or write to any IOCDS. Use the Security Definitions Page panel to do this by checking to see if the Input/Output (I/O) Configuration Control option has been turned on.
NOTE: The default is applicable to only classified systems.
Confirm whether or not the I/O Configuration Control option is checked.
If the Logical Partition is not restricted with read/write access to only its own IOCDS, this is a FINDING.
Fix Text (F-60481r890934_fix)
Review the Security Definition parameters specified under Processor Resource/Systems Manager (PR/SM).
Verify and implement the correct settings.
