Title

JES2 input sources must be properly controlled. (Cat II impact)

Discussion

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.

Check Content

Refer to the following report produced by the Data Set and Resource Data Collection: - SENSITVE.RPT(JESINPUT) Verify that the accesses for JESINPUT resources are restricted. If the guidance is true, this is not a finding. ___ The RACF resources and/or generic equivalent are defined with a default access of NONE. ___ The RACF resources and/or generic equivalent identified below will be defined with access restricted to the appropriate personnel: INTRDR nodename OFFn.* OFFn.JR OFFn.SR Rnnnn.RDm RDRnn STCINRDR TSUINRDR and/or TSOINRDR NOTE: Use common sense during the analysis. For example, access to the offload input sources should be limited to systems personnel (e.g., operations staff). ___ The RACF resource access authorizations are defined with UACC(NONE) and NOWARNING.

Fix Text

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.
