From z/OS Catalog Solutions for RACF STIG
Part of ZB000000
Associated with IA controls: ECCD-2, ECAR-2, ECCD-1, ECAR-1, DCSL-1
Catalog Solutions is a very powerful tool that can pose risks if not properly controlled. If security is not properly implemented, the users of the product could present data integrity exposures, bypass security for catalog datasets, other VSAM files and alias’s.
Catalog Solutions Install data sets provide the capability to use privileged functions and/or have access to sensitive data. Failure to properly restrict access to their data sets could result in violating the integrity of the base product which could result in compromising the operating system or sensitive data.
a) Refer to the following report produced by the Data Set and Resource Data Collection: - SENSITVE.RPT(CSLPROD) Automated Analysis Refer to the following report produced by the Data Set and Resource Data Collection: - PDI(ZCSL0000) b) Verify that access to the Catalog Solutions Install data sets are properly restricted. ___ The RACF data set rules for the data sets does not restrict UPDATE and/or ALTER access to only systems programming personnel. ___ The RACF data set rules for the data sets does not specify that all (i.e., failures and successes) UPDATE and/or ALTER access will be logged. c) If all of the above are untrue, there is NO FINDING. d) If any of the above is true, this is a FINDING.
The IAO will ensure that update and allocate access to program product data sets is limited to system programmers only, unless a letter justifying access is filed with the IAO, and all update and allocate access is logged.
The installing systems programmer will identify and document the product data sets and categorize them according to who will have UPDATE and ALTER access and if required that all UPDATE and ALTER access is logged. He will identify if any additional groups have UPDATE access for specific data sets, and once documented he will work with the IAO to see that they are properly restricted to the ACP (Access Control Program ) active on the system.
The following commands are provided as a sample for implementing dataset controls:
ad 'sys2.csl.**' uacc(none) owner(sys2) -
audit(success(update) failures(read)) -
data('Catalog Solution Vendor Datasets: Ref SRR PDI ZCSLR000')
pe 'sys2.csl.**' id(
Lavender hyperlinks in small type off to the right (of CSS
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
