z/OS CA Auditor for RACF Security Technical Implementation Guide

Version

V7R2

CCIs

CCI-000213

Discussion

CA Auditor 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 of customer data. Many utilities assign resource controls that can be granted to systems programmers only in greater than read authority. Resources are also granted to certain non systems personnel with read only authority.

Check Content

Refer to the following report produced by the Data Set and Resource Data Collection:

- SENSITVE.RPT(ZADT0020).

Automated Analysis
Refer to the following report produced by the Data Set and Resource Data Collection:

- PDI(ZADT0020).

Verify that the access to the LTDMMAIN resource in the PROGRAM resource class is restricted. If the following guidance is true, this is not a finding.

The RACF rules for the resources specify a default access of NONE.

The RACF rules for the resources are restricted access to system programmers, auditors, and security personnel.

All RACF rules are defined with UACC(NONE).

Fix Text

The ISSO will verify that the LTDMMAIN resource in the PROGRAM resource class is restricted to system programmers, auditors, and security personnel.

The RACF rules for the LTDMMAIN resource specify a default access of NONE and no RACF rules that allow access to the LTDMMAIN resource.

Example:

rdef program LTDMMAIN uacc(none) owner(admin) audit(failures(read)) -
data('added per PDI ZADT0020') 

The RACF rules for the LTDMMAIN resource is restricted access to systems programmers, auditors, and security personnel with access of READ. All RACF rules are defined with UACC(NONE).

Example:

rdef program ltdmmain -                
 addmem('SYS2A.EXAMINE.V120SP01.CAILIB'//nopadchk) -  
 data('Required by SRR PDI ZADTR020') -        
 audit(failures(read)) uacc(none) owner(admin)       
pe LTDMMAIN cl(program) id(syspaudt) acc(r)
pe LTDMMAIN cl(program) id(audtaudt) acc(r)
pe LTDMMAIN cl(program) id(secaaudt) acc(r)
