Description
V-224302mediumCICS 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.
V-224303mediumSensitive 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-224304mediumCICS 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 confidentiality, integrity, and availability of the CICS region, applications, and customer data.
V-224305mediumCICS 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 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.
V-224306mediumCICS 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. 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.
V-224307mediumCICS logonid(s) must be configured with proper timeout and signon limits.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.
V-224308mediumACF2/CICS parameter data sets are not protected in accordance with the proper security requirements.CICS is a transaction-processing product that provides programmers with the facilities to develop interactive applications. Unauthorized access to ACF2/CICS parameter data sets (i.e., product, security) could result in the compromise of the confidentiality, integrity, and availability of the CICS region, applications, and customer data.
V-224309mediumIBM 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 to systems programmers only in greater than read authority. Resources are also granted to certain non systems personnel with read only authority.
V-224310mediumCICS startup JCL statement is not specified in accordance with the 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 confidentiality, integrity, and availability of the CICS region, applications, and customer data.
V-224311mediumKey ACF2/CICS parameters must be properly coded.The ACF2/CICS parameters define the security controls in effect for CICS regions. Failure to code the appropriate values could result in degraded security. This exposure may result in unauthorized access impacting the confidentiality, integrity, and availability of the CICS region, applications, and customer data.
V-224312mediumSensitive CICS transactions are not protected in accordance with the proper 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-224313mediumSensitive CICS transactions are not protected in accordance with the proper 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.
