Finding ID	Severity	Title	Description
V-224500	Medium	CICS regions are improperly protected to prevent unauthorized propagation of the region userid.	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...
V-224499	Medium	External RACF Classes are not active for CICS transaction checking.	Implement CICS transaction security by utilizing two distinct and unique RACF resource classes (i.e., member and grouping) within each CICS region. If several CICS regions are grouped in an MRO environment, it is permissible for those grouped regions to share a common pair of resource classes. Member classes contain a...
V-224498	Medium	IBM CICS Transaction Server SPI command resources must be properly defined and protected.	IBM CICS Transaction Server 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...
V-224497	Medium	CICS logonid(s) must have time-out limit set to 15 minutes.	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...
V-224496	Medium	CICS default logonid(s) must be defined and/or controlled in accordance with the security requirements.	CICS is a transaction-processing product that provides programmers with the facilities to develop interactive applications. An improperly defined or controlled CICS default userid 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,...
V-224495	Medium	CICS region logonid(s) must be defined and/or controlled in accordance with the security requirements.	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...
V-224494	Medium	CICS System Initialization Table (SIT) parameter values must be specified in accordance with proper security requirements.	The CICS SIT is used to define system operation and configuration parameters of a CICS system. Several of these parameters control the security within a CICS region. Failure to code the appropriate values could result in unexpected operations and degraded security. This exposure may result in unauthorized access impacting the...
V-224493	Medium	Sensitive CICS transactions are not protected in accordance with security requirements.	Sensitive CICS transactions offer the ability to circumvent transaction level controls for accessing resources under CICS. These transactions must be protected so that only authorized users can access them. Unauthorized use can result in the compromise of the confidentiality, integrity, and availability of the operating system or customer data.
V-224492	Medium	CICS system data sets are not properly protected.	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.
