An XCCDF Rule

Description

<VulnDiscussion>CICS is a transaction-processing product that provides programmers with the facilities to develop interactive applications. Improperly defined or controlled CICS userids (i.e., region, default, and terminal users) 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.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>

Not granted the ACF2 NON-CNCL privilege.
Use the ACF2 LIST command to display the default CICS userid.
Example:
SET LID

CHANGE CICS NONON-CNCL

No access to interactive online facilities (e.g., TSO) other than CICS.

Non-restricted CICS transactions (e.g., CESF, CESN, 'good morning' transaction, etc.)

If applicable, resources necessary to operate in an intersystem communication (ISC) environment (i.e., LU6.1, LU6.2, and MRO)

Use the ACF2 ACFRPTRX or ACFRPTXR reports to verify if the CICS default userid has access to any resources or datasets.
