CICS system data sets are not properly protected.
An XCCDF Rule
Description
<VulnDiscussion>CICS is a transaction-processing product that provides programmers with the facilities to develop interactive applications. Unauthorized access to CICS system data sets (i.e., product, security, and application libraries) could result in the compromise of the confidentiality, integrity, and availability of the CICS region, applications, and customer data.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>

Remediation - Manual Procedure
Review the access authorizations for CICS system data sets for each region. Ensure they conform to the specifications below:
A CICS environment may include several data set types required for operation. Typically they are CICS product libraries, which are usually included in the STEPLIB concatenation but may be found in DD DFHRPL. CICS system data sets that can be identified with DFH DD statements, other product system data sets, and application program libraries. Restrict alter and update access to CICS program libraries and all system data sets to systems programmers only. Other access must be documented and approved by the IAO. The site may determine access to application data sets included in the DD DFHRPL and CICS region startup JCL according to need. Ensure that procedures are established; documented, and followed that prevents the introduction of unauthorized or untested application programs into production application systems.
