a) a) Refer Refer to the following report produced by the ACF2 Data Collection and Data Set and Resource Data Collection: - SENSITVE.RPT(FACILITY) - ACF2CMDS.RPT(RESOURCE) – Collection: - SENSITVE.RPT(FACILITY) - ACF2CMDS.RPT(RESOURCE) - Alternate report Automated Analysis Refer to the following report produced by the Data Set and Resource Data Collection: - PDI(ZHCD0020) b) Review Collection: - PDI(ZHCD0020) b) Review the following items for the IBM Hardware Configuration Definition (HCD) resources in the FACILITY resource class, TYPE(FAC): 1) The TYPE(FAC): 1) The ACF2 rules for the CBD resource specify a default access of NONE. 2) There NONE. 2) There are no ACF2 rules that allow access to the CBD resource. 3) The resource. 3) The ACF2 rules for the CBD.CPC.IOCDS and CBD.CPC.IPLPARM resources are restricted access to systems programming and operations personnel as well as possibly any automated operations batch users with access of READ. 4) The READ. 4) The ACF2 rules for the CBD.CPC.IOCDS and CBD.CPC.IPLPARM resources are restricted access to systems programming with access of UPDATE and logged. c) If logged. c) If any item in (b) is untrue, this is a FINDING. d) If finding. d) If all items in (b) are true, this is NOT A FINDING. not a finding.

Discussion

Program products can run with sensitive system privileges, and potentially can circumvent system controls. Failure to properly control access to program product resources could result in the compromise of the operating system environment, and compromise the confidentiality of customer data. Many utilities assign resource controls that can be granted to system programmers only in greater than read authority. Resources are also granted to certain non-systems non sytems personnel with read only authority.

Fix

The systems programmer will work with the IAO ISSO to verify that the following are properly specified in the ACP. 1) The ACP. 1) The ACF2 rules for the CBD resource specify a default access of NONE. 2) There NONE. 2) There are no ACF2 rules that allow access to the CBD resource. Example: SET R(FAC) $KEY(CBD) TYPE(FAC) - UID(*) PREVENT DATA(SRR FINDING FOR HCD) 3) The HCD) 3) The ACF2 rules for the CBD.CPC.IOCDS and CBD.CPC.IPLPARM resources are restricted access to systems programming and operations personnel as well as possibly any automated operations batch users with access of READ. 4) The READ. 4) The ACF2 rules for the CBD.CPC.IOCDS and CBD.CPC.IPLPARM resources are restricted access to systems programming with access of UPDATE and logged. Example: SET R(FAC) $KEY(CBD) TYPE(FAC) CPC.IOCDS.- UID(syspaudt) SERVICE(READ,UPDATE) LOG CPC.IOCDS.- UID(operaudt) SERVICE(READ) ALLOW CPC.IOCDS.- UID(autoaudt) SERVICE(READ) ALLOW CPC.IPLPARM.- UID(syspaudt) SERVICE(READ,UPDATE) LOG CPC.IPLPARM.- UID(operaudt) SERVICE(READ) ALLOW CPC.IPLPARM.- UID(autoaudt) SERVICE(READ) ALLOW
