Fix Recommendation

The IAO will ensure that the WRITER resource class is defined and required resource(s) is (are) defined to the WRITER resource class with no access.

Ensure the CLASMAP defines WRITER as TYPE(WTR).

NOTE: If CLASMAP defines WRITER as anything other than TYPE(WTR), replace WTR below with the appropriate three letters.

Ensure the following resources in the WRITER resource class (i.e., TYPE(WTR)):

JES2.- (backstop profile)
JES2.LOCAL.OFFn.- (spool offload transmitter)
JES2.LOCAL.OFFn.ST (spool offload SYSOUT transmitter)
JES2.LOCAL.OFFn.JT (spool offload job transmitter)
JES2.LOCAL.PRTn (local printer)
JES2.LOCAL.PUNn (local punch)
JES2.NJE.nodename (NJE node)
JES2.RJE.Rnnnn.PRm (remote printer)
JES2.RJE.Rnnnn.PUm (remote punch)

Ensure the following items are in effect:

1) The CLASMAP record defines the WRITER resource class.

Example:

SHOW CLASMAP

2) The JES2.- resource is defined to the WRITER resource class with a default access of PREVENT.

3) The other resources mentioned in (b) are protected by generic and/or fully qualified rules defined to the WRITER resource class with a default access of PREVENT.

NOTE: A default access of READ is allowed for output destinations that are permitted to route output for all users. Currently, there is no guidance on which output destinations are appropriate for a default access of READ. However, common sense should prevail during the analysis. For example, a default access of READ would typically be inappropriate for RJE, NJE, and offload output destinations.

Examples:

$KEY(JES2) TYPE(WTR)
LOCAL.OFF- UID(*) PREVENT
LOCAL.OFF-.JT UID(*) PREVENT
LOCAL.OFF-.ST UID(operaudt) SERVICE(READ) ALLOW
LOCAL.OFF-.ST UID(syspaudt) SERVICE(READ) ALLOW
LOCAL.OFF-.ST UID(secaaudt) SERVICE(READ) ALLOW
LOCAL.OFF-.ST UID(*) PREVENT
LOCAL.PRT- UID(*) SERVICE(READ) ALLOW
LOCAL.PUN- UID(*) PREVENT
NJE.- UID(*) SERVICE(READ) ALLOW
RJE.- UID(syspaudt) SERVICE(READ) ALLOW
RJE.- UID(*) PREVENT
- UID(*) PREVENT

Check Contents

a) Refer to the following reports produced by the ACF2 Data Collection:

- SENSITVE.RPT(WRITER)
- ACF2CMDS.RPT(RESOURCE) – Alternate report
- ACF2CMDS.RPT(ACFGSO)

b) Review the ACFGSO report. If CLASMAP defines WRITER as TYPE(WTR), There is NO FINDING.

NOTE: If CLASMAP defines WRITER as anything other than TYPE(WTR), replace WTR below with the appropriate three letters.

Refer to the following reports produced by the z/OS Data Collection:

- EXAM.RPT(SUBSYS)
- PARMLIB(JES2 parameters)

c) Review the following resources in the WRITER resource class (i.e., TYPE(WTR)):

JES2.- (backstop profile)
JES2.LOCAL.OFFn.- (spool offload transmitter)
JES2.LOCAL.OFFn.ST (spool offload SYSOUT transmitter)
JES2.LOCAL.OFFn.JT (spool offload job transmitter)
JES2.LOCAL.PRTn (local printer)
JES2.LOCAL.PUNn (local punch)
JES2.NJE.nodename (NJE node)
JES2.RJE.Rnnnn.PRm (remote printer)
JES2.RJE.Rnnnn.PUm (remote punch)

NOTE 1: JES2 is typically the name of the JES2 subsystem. Refer to the SUBSYS report and locate the entry with the description of PRIMARY JOB ENTRY SUBSYSTEM. The SUBSYSTEM NAME of this entry is the name of the JES2 subsystem.

NOTE 2: OFFn, where n is the number of the offload transmitter. Determine the numbers by searching for OFF( in the JES2 parameters.

NOTE 3: PRTn, where n is the number of the local printer. Determine the numbers by searching for PRT( in the JES2 parameters.

NOTE 4: PUNn, where n is the number of the local card punch. Determine the numbers by searching for PUN( in the JES2 parameters.

NOTE 5: Nodename is the NAME parameter value specified on the NODE statement. Review the JES2 parameters for NJE node definitions by searching for NODE( in the report.

NOTE 6: Rnnnn.PRm, where nnnn is the number of the remote workstation and m is the number of the printer. Determine the numbers by searching for .PR in the JES2 parameters.

NOTE 7: Rnnnn.PUm, where nnnn is the number of the remote workstation and m is the number of the punch. Determine the numbers by searching for .PU in the JES2 parameters.

d) Ensure the following items are in effect:

1) The CLASMAP record defines the WRITER resource class.
2) The JES2.- resource is defined to the WRITER resource class with a default access of PREVENT.
3) The other resources mentioned in (b) are protected by generic and/or fully qualified rules defined to the WRITER resource class with a default access of PREVENT.

NOTE: A default access of READ is allowed for output destinations that are permitted to route output for all users. Currently, there is no guidance on which output destinations are appropriate for a default access of READ. However, common sense should prevail during the analysis. For example, a default access of READ would typically be inappropriate for RJE, NJE, and offload output destinations.

e) If all of the items mentioned in (b) and (d) are true, there is NO FINDING.

f) If any item mentioned in (b) or (d) is untrue, this is a FINDING.
