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 sytems personnel with read only authority.
a) Refer to the following report produced by the ACF2 Data Collection and Data Set and Resource Data 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 the following items for the IBM Hardware Configuration Definition (HCD) resources in the FACILITY resource class, TYPE(FAC): 1) The ACF2 rules for the CBD resource specify a default access of NONE. 2) There are no ACF2 rules that allow access to the CBD 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 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 any item in (b) is untrue, this is a FINDING. d) If all items in (b) are true, this is NOT A FINDING.
The systems programmer will work with the IAO to verify that the following are properly specified in the ACP. 1) The ACF2 rules for the CBD resource specify a default access of 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 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 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
Lavender hyperlinks in small type off to the right (of CSS
class id, if you view the page source) point to
globally unique URIs for each document and item. Copy the
link location and paste anywhere you need to talk
unambiguously about these things.
You can obtain data about documents and items in other
formats. Simply provide an HTTP header Accept:
