Fix Recommendation

The IAO will ensure that access authorization for resources defined to the JESTRACE and SYSLOG resources in the JESSPOOL resource class is restricted to the appropriate personnel.

Review the following resources defined to the JESSPOOL resource class:

Ensure the following resources are defined to the JESSPOOL resource class with a UACC(NONE):

localnodeid.JES2.$TRCLOG.taskid.*.JESTRACE
localnodeid.+MASTER+.SYSLOG.jobid.*.SYSLOG or
localnodeid.+BYPASS+.SYSLOG.jobid.*.SYSLOG

NOTE: These resource profiles may be more generic as long as they pertain directly to the JESTRACE and SYSLOG data sets. For example:

localnodeid.JES2.$TRCLOG.*.**
localnodeid.+MASTER+.SYSLOG.*.** or
localnodeid.+BYPASS+.SYSLOG.*.**

NOTE: Review the JES2 parameters to determine the localnodeid by searching for OWNNODE in the NJEDEF statement, and then searching for NODE(nnnn) (where nnnn is the value specified by OWNNODE). The NAME parameter value specified on this NODE statement is the localnodeid. Another method is to issue the JES2 command $D NODE,NAME,OWNNODE=YES to obtain the NAME of the OWNNODE.

Ensure that access authorization for the resources mentioned above is restricted to the following:

Userid(s) associated with external writer(s) can have complete access.

NOTE: An external writer is a STC that removes data sets from the JES spool. In this case, it is responsible for archiving the JESTRACE and SYSLOG data sets. The STC default name is XWTR and the external writer program is called IASXWR00.

Systems personnel and security administrators responsible for diagnosing JES2 and z/OS problems can have complete access.

Application Development and Application Support personnel responsible for diagnosing application problems can have READ access to the SYSLOG resource.

Examples:

RDEFINE JESSPOOL localnodeid.JES2.$TRCLOG.*.** audit(failures(read)) uacc(NONE) -
data('Reference srr finding ZJES0044 ') owner(admin)

RDEFINE JESSPOOL localnodeid.+MASTER+.SYSLOG.*.** audit(failures(read)) uacc(NONE) -
data('Reference srr finding ZJES0044') owner(admin)
or
RDEFINE JESSPOOL localnodeid.+BYPASS+.SYSLOG.*.** audit(failures(read)) uacc(NONE) -
data('Reference srr finding ZJES0044') owner(admin)

PE localnodeid.JES2.$TRCLOG.** cl(jesspool) id(<syspaudt> <secaaudt>) acc(a)
PE localnodeid.+MASTER+.SYSLOG.*.** cl(jesspool) id(<syspaudt> <secaaudt>) acc(a)
PE localnodeid.+MASTER+.SYSLOG.*.** cl(jesspool) id(<appdpaudt> <appsaudt>) acc(r)
or
PE localnodeid.+BYPASS+.SYSLOG.*.** cl(jesspool) id(<syspaudt> <secaaudt>) acc(a)
PE localnodeid.+BYPASS+.SYSLOG.*.** cl(jesspool) id(<appdpaudt> <appsaudt>) acc(r)

Refer to the following report produced by the RACF Data Collection and Data Set and Resource Data Collection:

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

- PARMLIB(JES2 parameters)

Review the following resources defined to the JESSPOOL resource class:

localnodeid.JES2.$TRCLOG.taskid.*.JESTRACE
localnodeid.+MASTER+.SYSLOG.jobid.*.SYSLOG or
localnodeid.+BYPASS+.SYSLOG.jobid.-.SYSLOG

NOTE: These resource profiles may be more generic as long as they pertain directly to the JESTRACE and SYSLOG data sets. For example:

localnodeid.JES2.*.*.*.JESTRACE
localnodeid.+MASTER+.*.*.*.SYSLOG or
localnodeid.+BYPASS+.*.*.*.SYSLOG

NOTE: Review the JES2 parameters to determine the localnodeid by searching for OWNNODE in the NJEDEF statement, and then searching for NODE(nnnn) (where nnnn is the value specified by OWNNODE). The NAME parameter value specified on this NODE statement is the localnodeid. Another method is to issue the JES2 command $D NODE,NAME,OWNNODE=YES to obtain the NAME of the OWNNODE.

Ensure that access authorization for the resources mentioned above is restricted to the following:

1) Userid(s) associated with external writer(s) can have complete access.

NOTE: An external writer is an STC that removes data sets from the JES spool. In this case, it is responsible for archiving the JESTRACE and SYSLOG data sets. The STC default name is XWTR and the external writer program is called IASXWR00.

2) Systems personnel and security administrators responsible for diagnosing JES2 and z/OS problems can have complete access.

3) Application Development and Application Support personnel responsible for diagnosing application problems can have READ access to the SYSLOG resource.
