Overview

Finding ID	Version	Rule ID	IA Controls	Severity
V-6920	ZJES0022	SV-74867r1_rule		Medium

Description
JES2 input sources provide a variety of channels for job submission. Failure to properly control the use of these input sources could result in unauthorized submission of work into the operating system. This exposure may threaten the integrity and availability of the operating system environment, and compromise the confidentiality of customer data.

Fix Text (F-16909r3_fix)
Verify with the ISSO that access authorization for resources defined to the JESINPUT resource class is restricted to the appropriate personnel Grant read access to authorized users for each of the following input sources: INTRDR nodename OFFn.* OFFn.JR OFFn.SR Rnnnn.RDm RDRnn STCINRDR TSUINRDR and/or TSOINRDR The resource definition will be generic if all of the resources of the same type have identical access controls (e.g., if all off load receivers are equivalent). The default access will be NONE except for sources that are permitted to submit jobs for all users. Those resources may be defined as either NONE or READ.
