Vulnerability discussion

Configuration properties of DFSMS are specified in various members of the system parmlib concatenation (e.g., SYS1.PARMLIB). Statements within these PDS members provide the execution, operational, and configuration characteristics of the system-managed storage environment. Missing or inappropriate configuration values may result in undesirable operations and degraded security. This exposure could potentially compromise the availability and integrity of some system services and customer data.

Check content

a) Review the SYS1.PARMLIB(IEFSSNxx) data set for the following SMS parameter settings: 1) Keyword syntax: SUBSYS SUBNAME(SMS) INITRTN(IGDSSIIN) 2) Positional syntax: SMS, IGDSSIIN b) If the required parameters are defined, there is NO FINDING. c) If the required parameters are not defined, this is a FINDING.

Fix text

Review the DFSMS-related PDS members and statements specified in the system parmlib concatenation. Ensure these elements are configured as outlined below Keyword syntax: SUBSYS SUBNAME(SMS) INITRTN(IGDSSIIN) Positional syntax: SMS, IGDSSIIN

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.
