The system-wide options control the default settings for determining how the ACP will function when handling requests for access to the operating system environment, ACP, and customer data. The ACP provides the ability to set a number of these fields at the subsystem level. If no setting is found, the system-wide defaults will be used. The improper setting of any one of these fields, individually or in combination with another, can compromise the security of the processing environment. In addition, failure to establish standardized settings for the ACP control options introduces the possibility of exposure during a migration process or contingency plan activation.
a) Refer to the following report produced by the ACF2 Data Collection: - ACF2CMDS.RPT(ACFGSO) Automated Analysis Refer to the following report produced by the ACF2 Data Collection: - PDI(ACF0330) b) If the GSO LINKLST record values conform to the following requirements, there is NO FINDING. Specifies one or more partitioned data sets considered part of the system link (SYS1.LINKLIB) during data set access validation. Only trusted system data sets will be listed. Application libraries will never be included. Example: LIBRARY(SYS1.LINKLIB SYS2A.FDR.LOADLIB) c) If there is any deviation from the above requirements in the GSO LINKLST record values, this is a FINDING.
The IAO will ensure the LINKLIST GSO value if specified only contains trusted system datasets. Specifies one or more partitioned data sets considered part of the system link (SYS1.LINKLIB) during data set access validation. Only trusted system data sets will be listed. Application libraries will never be included. Example: SET C(GSO) INSERT LINKLST LIBRARY(SYS1.LINKLIB SYS2A.FDR.LOADLIB) F ACF2,REFRESH(LINKLST)
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:
