z/OS ROSCOE for ACF2 STIG Version Comparison

There are 2 differences between versions v6 r7 (Jan. 20, 2015) (the "left" version) and v6 r9 (Nov. 23, 2022) (the "right" version).

Check ZROSA020 was changed between these two versions. Green, underlined text was added, red, struck-out text was removed.

The regular view of the left check and right check may be easier to read.

If the following guidance is true, this is not a finding. ___ The finding. ___ The ACF2 resources are defined with a default access of PREVENT. ___ The PREVENT. ___ The ACF2 resource access authorizations restrict access to the appropriate personnel. ___ The personnel. ___ The ACF2 resource logging is correctly specified.

Discussion

ROSCOE can run with sensitive system privileges, and potentially can circumvent system controls. Failure to properly control access to product resources could result in the compromise of the operating system environment, and compromise the confidentiality and integrity 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 systems personnel with read only authority.

Fix

The IAO ISSO will work with the systems programmer to verify that the following are properly specified in the ACP. (Note: The resource type, resources, and/or resource prefixes identified below are examples of a possible installation. The actual resource type, resources, and/or resource prefixes are determined when the product is actually installed on a system through the product’s product's installation guide and can be site specific.) Ensure that all ROSCOE resources and/or generic equivalent are properly protected according to the requirements specified in CA ROSCOE Resources table in the z/OS STIG Addendum. Use CA ROSCOE Resources table in the z/OS STIG Addendum. This table lists the resources, access requirements, and logging requirements for ROSCOE ensure the following guidelines are followed: The ACF2 resources are defined with a default access of PREVENT. The ACF2 resource access authorizations restrict access to the appropriate personnel. The ACF2 resource logging is correctly specified. The following commands are provided as a sample for implementing resource controls: $KEY(rosid) TYPE(ROS) ROSCMD.ETSO UID(*) SEVICE(READ) ROSCMD.MONITOR.- UID(syspaudt) ALLOW ROSCMD.MONITOR.AMS UID(syspaudt) ALLOW ROSCMD.MONITOR.AMS UID(*) SEVICE(READ) ROSCMD.- UID(syspaudt) ALLOW - UID(*) PREVENT
