Fix Recommendation

Configure 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.

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

From the ISPF Command Shell enter:
TSS WHOHAS WRITER(JES2.)

If the TSS WRITER resource or generic equivalent identified above is defined with access restricted to the appropriate personnel, this is not a finding.

If the TSS WRITER resource or generic equivalent identified above is not defined with access restricted to the appropriate personnel, this is a finding.

From the ISPF Command Shell enter:
TSS LIST RDT(*)

If the JESINPUT RESOURCE does not have DEFPROT as an attribute, this is a finding.
