Vulnerability discussion

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(ACF0360) b) If the GSO NJE record values conform to the following requirements, there is NO FINDING. Specifies ACF2 validation options that apply to jobs submitted through a network job entry subsystem (JES2, JES3, RSCS). Example: DFTLID() INHERIT NODEMASK(-) ENCRYPT VALIN(YES) NOVALOUT NOTE: For NJE nodes that are incompatible with the XDES algorithm, discrete NJE records will be created with NOENCRYPT. NOTE: Local changes will be documented in writing with supporting documentation. c) If there is any deviation from the above requirements in the GSO NJE record values, this is a FINDING.

Pro Tips

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: text/turtle or Accept: application/rdf+xml.
