Rules in z/OS BMC IOA for TSS Security Technical Implementation Guide
Description
V-224598CAT II · MediumBMC IOA security exits are not installed or configured properly.The BMC IOA security exits enable access authorization checking to BMC IOA commands, features, and online functionality. If these exit(s) is (are) not in place, activities by unauthorized users may result. BMC IOA security exit(s) interface with the Access Control Program (ACP). If an unauthorized exit was introduced into the operating environment, system security could be weakened or bypassed. These exposures may result in the compromise of the operating system environment, ACP, and customer data.
V-224599CAT II · MediumBMC IOA installation data sets will be properly protected.BMC IOA installation data sets have the ability to use privileged functions and/or have access to sensitive data. Failure to properly restrict access to these data sets could result in violating the integrity of the base product, which could result in compromising the operating system or sensitive data.
V-224600CAT II · MediumBMC IOA STC data sets must be properly protected.BMC IOA STC data sets have the ability to use privileged functions and/or have access to sensitive data. Failure to properly restrict access to these data sets could result in violating the integrity of the base product which could result in compromising the operating system or sensitive data.
V-224601CAT II · MediumBMC IOA User data sets will be properly protected.BMC IOA User data sets, IOA Core and Repository, have the ability to use privileged functions and/or have access to sensitive data. Failure to properly restrict access to these data sets could result in violating the integrity of the base product, which could result in compromising the operating system or sensitive data.
V-224602CAT II · MediumBMC IOA resources must be properly defined and protected.BMC IOA 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-224603CAT II · MediumBMC IOA Started Task name must be properly identified and defined to the system ACP.BMC IOA requires a started task that will be restricted to certain resources, data sets, and other system functions. Defining the started task as a userid to the system ACP allows the ACP to control the access and authorized users that require these capabilities. Failure to properly control these capabilities could compromise the operating system environment, ACP, and customer data.
V-224604CAT II · MediumBMC IOA Started task(s) must be properly defined to the Started Task Table ACID for Top Secret.Access to product resources should be restricted to only those individuals responsible for the application connectivity and who have a requirement to access these resources. Improper control of product resources could potentially compromise the operating system, ACP, and customer data.
V-224605CAT II · MediumBMC IOA is not properly defined to the Facility Matrix Table for Top Secret.Improperly defined security controls for BMC IOA could result in the compromise of the network, operating system, and customer data.
V-224606CAT II · MediumBMC IOA configuration/parameter values are not specified properly.BMC IOA configuration/parameters control the security and operational characteristics of products. If these parameter values are improperly specified, security and operational controls may be weakened. This exposure may threaten the availability of the product applications, and compromise the confidentiality of customer data.
