Refer to the following report produced by the Data Set and Resource Data Collection: - SENSITVE.RPT(NETVRPT). Automated Analysis Refer to the following report produced by the Data Set and Resource Data Collection: - PDI(ZNET0000). Verify that access to the NetView install data sets are properly restricted. If the following guidance is true, this is not a finding. The RACF data set rules for the data sets does not restrict UPDATEWRITE and/or ALTERgreater access to systems programming personnel. The RACF data set rules for the datasetsdata doessets not specify that all (i.e., failures and successes) UPDATEWRITE and/or ALTERgreater access will be logged. If all of the above are untrue, this is not a finding. If any of the above is true, this is a finding.

The ISSO will ensure that updateWRITE and/or allocategreater access to NetView install data sets is limited to system programmers only and all updateWRITE and/or allocategreater access is logged. Auditors should be granted READ access. The installing systems programmer will identify and document the product data sets and categorize them according to who will have updateWRITE and/or altergreater access and if required that all updateWRITE and/or allocategreater access is logged. The installing systems programmer will identify if any additional groups have updateUPDATE access for specific data sets, and once documented, will work with the ISSO to ensure they are properly restricted to the Access Control Program (ACP) active on the system. Data sets to be protected will be: SYS2.NETVIEW SYS2A.NETVIEW SYS3.NETVIEW ad 'sys2.netview.**' uacc(none) owner(sys2) - audit(success(update) failures(read)) pe 'sys2.netview.**' id(syspaudt) acc(a) pe 'sys2.netview.**' id(audtaudt) ad 'sys2a.netview.**' uacc(none) owner(sys2a) - audit(success(update) failures(read)) pe 'sys2a.netview.**' id(syspaudt) acc(a) pe 'sys2a.netview.**' id(audtaudt) ad 'sys3.netview.**' uacc(none) owner(sys3) - audit(success(update) failures(read)) pe 'sys3.netview.**' id(syspaudt) acc(a) pe 'sys3.netvidew.**' id(audtaudt)

The IAOISSO will ensure that updateWRITE and/or allocategreater access to NetView STC data sets are limited to System Programmers and NetView STC only, unless a letter justifying access is filed with the IAOISSO. Auditors should have READ access. The installing Systems Programmer will identify and document the product data sets and categorize them according to who will have updateWRITE and/or altergreater access and if required that all updateWRITE and/or allocategreater access is logged. He will identify if any additional groups have updateWRITE and/or altergreater access for specific data sets, and once documented he will work with the IAOISSO to see that they are properly restricted to the ACP (Access Control Program) active on the system.

Fix text

The NetView systemsystems programerprogrammer and the IAOISSO will ensure that the product's Started Task(s) is properly Identified / defined to the System ACP. Most installation manuals will indicate how the Started Task is identified and any additional attributes that must be specified. A sample is provided here: au cnmpssi name('stc, netview') nopass dfltgrp(stc) - owner(stc) data('netview subsystem interface') au cnmproc name('stc, netview') nopass dfltgrp(stc) - owner(stc) data('netview')

Discussion

NetView requires a started task(s) that will be restricted to certain resources, datasetsdata sets, and other system functions. ByDefining defining the started task as a userid to the system ACP, It allows the ACP to control the access and authorized users that require these capabilities. Failure to properly control these capabilities, could compromise of the operating system environment, ACP, and customer data.

Verify that the IBM Tivoli NetView started task(s) is (are) defined to the STARTED resource class profile and/or ICHRIN03 table entry, this is not a finding.

Fix text

The IBM Tivoli NetView system programmer and the IAOISSO will ensure that a product's started task(s) is (are) properly identified and/or defined to the System ACP. A unique userid must be assigned for the IBM Tivoli NetView started task(s) thru a corresponding STARTED class entry. The following sample set of commands is shown here as a guideline: rdef started CNMPROC.** uacc(none) owner(admin) audit(all(read)) stdata(user(CNMPROC) group(stc)) rdef started CNMPSSI.** uacc(none) owner(admin) audit(all(read)) stdata(user(CNMPSSI) group(stc)) setr racl(started) ref

Discussion

Access to product resources shouldmust be restricted to only those individuals responsible for the application connectivity and who have a requirement to access these resources. Improper control of product resources could potentially compromise the operating system, ACP, and customer data.
