Vulnerability 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.

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: 1) A unique userid is defined. Use the RACF Adduser command to accomplish this. A sample command is provided here: AU NAME('STC, CICS Region') DFLTGRP(STC) OWNER(STC) 2) Defined to the STARTED resource class. Use the RACF RDEFINE command. A sample is provided here: RDEF STARTED .** UACC(NONE) OWNER(ADMIN) DATA('USED TO MAP TO A VALID RACF USERID') STDATA(USER(=MEMBER) GROUP(STC) TRACE(YES))

Pro Tips

Lavender hyperlinks in small type off to the right (of CSS class id, if you view the page source) point to globally unique URIs for each document and item. Copy the link location and paste anywhere you need to talk unambiguously about these things.

You can obtain data about documents and items in other formats. Simply provide an HTTP header Accept: text/turtle or Accept: application/rdf+xml.
