IBM z/OS libraries included in the system REXXLIB concatenation must be properly protected.
An XCCDF Rule
Description
Access control policies include: identity-based policies, role-based policies, and attribute-based policies. Access enforcement mechanisms include: access control lists, access control matrices, and cryptography. These policies and mechanisms must be employed by the application to control access between users (or processes acting on behalf of users) and objects (e.g., devices, files, records, processes, programs, and domains) in the information system. Satisfies: SRG-OS-000080-GPOS-00048, SRG-OS-000259-GPOS-00100, SRG-OS-000324-GPOS-00125

A Manual Procedure
Evaluate the impact of correcting the deficiency. Develop a plan of action and implement the changes required to protect APF Authorized Libraries.
Configure ESM dataset rules to limit WRITE or greater access to libraries included in the system REXXLIB concatenation to system programmers only.
Configure ESM dataset rules allow READ access to only appropriate Started Tasks and Auditors.
Configure ESM dataset rules to log UPDATE and/or ALTER access (i.e., successes and failures).
