z/OS IBM CICS Transaction Server for RACF Security Technical Implementation Guide

Version

V7R2

CCIs

CCI-000764

Discussion

CICS is a transaction-processing product that provides programmers with the facilities to develop interactive applications. Improperly defined or controlled CICS region userids may provide an exposure and vulnerability within the CICS environment. This could result in the compromise of the confidentiality, integrity, and availability of the CICS region, applications, and customer data. The region userid should be associated with a unique RACF userid.

Check Content

Refer to the following report produced by the z/OS Data Collection:

- EXAM.RPT(CICSPROC).

Refer to the following reports produced by the RACF Data Collection:

- RACFCMDS.RPT(LISTUSER).
- DSMON.RPT(RACCDT).

Refer to the CICS Systems Programmer Worksheets filled out from previous vulnerability ZCIC0010.

If the following is defined for each CICS region, this is not a finding.

A unique userid is defined.
Defined to the STARTED resource class.

Fix Text

Review all CICS region, default, and end-user userids to ensure they are defined and controlled as required.

Ensure that the following is defined for each CICS region:

A unique userid is defined.

Use the RACF Adduser command to accomplish this. A sample command is provided here:

AU <cicsregionid> NAME('STC, CICS Region') DFLTGRP(STC) OWNER(STC) 

Defined to the STARTED resource class.

Use the RACF RDEFINE command. A sample is provided here:

RDEF STARTED <cicsprocname>.** UACC(NONE) OWNER(ADMIN) DATA('USED TO MAP <cicsprocname> TO A VALID RACF USERID') STDATA(USER(=MEMBER) GROUP(STC) TRACE(YES))
