Fix Recommendation

Configure the access authorization for resources defined to the WRITER resource class to be restricted to the operators and system programmers on a classified system only.

Define resources in the ACP’s respective WRITER class for each of the following output destinations:

JES2.LOCAL.devicename
JES2.LOCAL.OFFn.*
JES2.LOCAL.OFFn.JT
JES2.LOCAL.OFFn.ST
JES2.LOCAL.PRTn
JES2.LOCAL.PUNn
JES2.NJE.nodename
JES2.RJE.devicename

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 transmitters are equivalent). If all users are permitted to route output to a specific destination, the resource controlling it may be defined with a default access of either NONE or READ. Otherwise it will be defined with a default access of NONE.

Check Contents

If the Classification of the system is Unclassified, this is not applicable.

Verify that the accesses for WRITER resources are restricted.

If the following guidance is true, this is not a finding.

The ACF2 resources and/or generic equivalent are defined with a default access of PREVENT.

The ACF2 resources and/or generic equivalent identified below will be defined with access restricted to the operators and system programming personnel:

JES2.LOCAL.devicename
JES2.LOCAL.OFFn.*
JES2.LOCAL.OFFn.JT
JES2.LOCAL.OFFn.ST
JES2.LOCAL.PRTn
JES2.LOCAL.PUNn
JES2.NJE.nodename
JES2.RJE.devicename

NOTE: Common sense should prevail during the analysis. For example, access to the offload output destinations should be limited to only systems personnel (e.g., operations staff/system programmers) on a classified system.
