IBM RACF must limit WRITE or greater access to LINKLIST libraries to system programmers only.
An XCCDF Rule
Description
<VulnDiscussion>The primary function of the LINKLIST is to serve as a single repository for commonly used system modules. Failure to ensure that the proper set of libraries is designated for LINKLIST can impact system integrity, performance, and functionality. For this reason, controls must be employed to ensure that the correct set of LINKLIST libraries is used. Unauthorized access could result in the compromise of the operating system environment, ACP, and customer data.
