Vanguard Security Solutions resources will be properly defined and protected.

Overview

Finding ID	Version	Rule ID	IA Controls	Severity
V-17947	ZVSSR020	SV-24912r2_rule	ECCD-1 ECCD-2	Medium

Description
Program products 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.

Fix Text (F-18529r5_fix)
The IAO will work with the systems programmer to verify that the following are properly specified in the ACP. (Note: The resources, and/or resource prefixes identified below are examples of a possible installation. The actual resources, and/or resource prefixes are determined when the product is actually installed on a system through the product’s installation guide and can be site specific.) Use Vanguard Security Solutions Resources and Vanguard Security Solutions Resources Descriptions tables in the zOS STIG Addendum. These tables list the resources, descriptions, and access and logging requirements. Ensure the guidelines for the resources and/or generic equivalent specified in the z/OS STIG Addendum are followed. The following commands are provided as a sample for implementing resource controls: rdef facility vra$.acstask. uacc(none) owner(admin) – audit(all(read)) - data('protected per zvssr020') pe vra$.acstask. cl(facility) id() acc(read) pe vra$.acstask.** cl(facility) id() acc(read)
