System Installation Checklists

To complete the checklists in this chapter, you use options from the Installation Choices Menu. Select option 2 from the Primary Menu to access this menu.

The audit tests described in these checklists analyze the integrity of the libraries and functions that control many important z/OS functions. The following list describes the function of each checklist:

z/OS Parameter Library

Review the integrity of the logical Parmlib, which is the system parameter library. The logical Parmlib is sometimes called SYS1.PARMLIB; however, it can, in fact, comprise more than one concatenated system parameter data sets, which together form the logical Parmlib. See Parameter Library next for more information about designating the logical parmlib data set or data sets.

You can designate the logical Parmlib data set or data sets as follows:

• IEFPARM DD statement in the master JCL MSTJCLxx member used to start the master scheduler address space. This MSTJCLxx member (default is MSTJCL00) can reside in the SYS1.LINKLIB data set or as a card-image member in the actual SYS1.PARMLIB data set.
• One or more PARMLIB statements within the system LOADxx member used at IPL. Note that PARMLIB statements within the LOADxx member, if present, will completely override any logical Parmlib data sets specified by the IEFPARM DD statement in the master JCL member.
• If neither of the previous approaches is used, the system will use SYS1.PARMLIB by default. In addition, if either approach is used and SYS1.PARMLIB is not included, the system will include it by default.

APF‑Authorized Libraries

Review APF‑authorized programs that can run with special privileges and potentially sidestep the security mechanisms of z/OS and access control software.

System Modification Program

Analyze the integrity of consolidated software inventories (CSIs) to determine whether SMP/E updated a program.

Key z/OS Libraries

Review the administration of the system libraries.

Time Sharing Option

Review the integrity of the TSO user attribute data set, SYS1.UADS.

z/OS Catalog Display

Review the access controls that protect the z/OS catalogs.

Use the W/P Ref column on these checklists to record a cross‑reference to the work paper that documents your findings about the aspect of z/OS that the checklist analyzes.
