ROSCOE resources are not properly defined and protected.

From z/OS ROSCOE for TSS STIG

Part of ZB000020

Associated with IA controls: ECCD-2, ECCD-1

SV-23709r1_rule ROSCOE resources are not properly defined and protected.

Vulnerability discussion

ROSCOE 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.

Check content

a) Refer to the following reports produced by the TSS Data Collection and Data Set and Resource Data Collection: - SENSITVE.RPT(ZROS0020) Automated Analysis Refer to the following report produced by the Data Set and Resource Data Collection: - PDI(ZROS0020) b) Review the following items for the ROSRES resource class: 1) The ACP identifies ownership of all ROSCOE resource prefixes or ROSRES resource class has the attribute of DEFPROT. 2) If ACP rules to ROSCOE resources defined in the ROSCOE Resources table, in the z/OS STIG Addendum, is restricted to the appropriate personnel. 3) The ACP rules are logged as indicated in the ROSCOE Resources table, in the z/OS STIG Addendum. 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.

Fix text

The systems programmer will work with the IAO to verify that the following are properly specified in the ACP 1) The ROSCOE Resources are properly defined and proper access is restricted according to the CA ROSCOE Resources table, in the z/OS STIG Addendum. 2) Verify that logging is specified according to the CA ROSCOE Resources table, in the z/OS STIG Addendum The systems programmer will see that the questionaire member for this product vulnerability contains the resouces, authorized users access levels and logging requirements, based on the sites requirements.

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.
