None Computing title z/OS Quest NC-Pass for TSS Security Technical Implementation Guide version 7 releaseinfo Release: 2 Vuln_Num V-225592 Rule_ID SV-225592r1146361_rule Severity medium Rule_Title Quest NC-Pass installation data sets will be properly protected. Vuln_Discuss Quest NC-Pass 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. Check_Content Refer to the following report produced by the Data Set and Resource Data Collection: - SENSITVE.RPT(NCPASRPT). Automated Analysis Refer to the following report produced by the Data Set and Resource Data Collection: - PDI(ZNCP0000). Verify that the accesses to the Quest NC-Pass installation data sets are properly restricted. If the following guidance is true, this is not a finding. The TSS data set rules for the data sets restrict READ access to all authorized users. The TSS data set rules for the data sets restrict WRITE and/or greater access to systems programming personnel. The TSS data set rules for the data sets specify that all (i.e., failures and successes) WRITE and/or greater access is logged. Fix_Text The ISSO will ensure that WRITE and/or greater access to Quest NC-Pass installation data sets is limited to systems programmers only, and all WRITE and/or greater access is logged. READ access can be given to all authorized users. The installing systems programmer will identify and document the product data sets and categorize them according to who will have WRITE and/or greater access and, if required, that all WRITE and/or greater access is logged. The installing systems programmer will identify if any additional groups have WRITE and/or greater access for specific data sets, and once documented will work with the ISSO to ensure they are properly restricted to the Access Control Program (ACP) active on the system. Data sets to be protected will be: SYS2.NCPASS SYS3.NCPASS (Data sets that are not altered by product STCs; this can be more specific) The following commands are provided as a sample for implementing data set controls: TSS PERMIT(<syspaudt>) DSN(SYS2.NCPASS.)

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. Check_Content Refer to the following report produced by the Data Set and Resource Data Collection: - SENSITVE.RPT(NCPASSTC). Automated Analysis Refer to the following report produced by the Data Set and Resource Data Collection: - PDI(ZNCP0001). Verify that the accesses to the Quest NC-Pass STC data sets are properly restricted. If the following guidance is true, this is not a finding. The TSS data set rules for the data sets restrict READ access to auditors. The TSS data set rules for the data sets restrict UPDATE access to domain level security administrators. The TSS data set rules for the data sets restrict WRITE and/or greater access to systems programming personnel. The TSS data set rules for the data sets restrict WRITE and/or greater access to the Quest NC-Pass's STC(s) and/or batch user(s). Fix_Text The ISSO will ensure that WRITE and/or greater access to Quest NC-Pass STC data sets is limited to systems programmers and/or Quest NC-Pass's STC(s) and/or batch user(s) only.

Data sets to be protected will be: SYS3.NCPASS.*.PASSCAF SYS3.NCPASS.*.PASSVSDD The following commands are provided as a sample for implementing data set controls: TSS PERMIT(<syspaudt>) DSN(SYS3.NCPASS.*.PASSCAF) ACCESS(ALL) TSS PERMIT(<tstcaudt>) DSN(SYS3.NCPASS.*.PASSCAF) ACCESS(ALL) TSS PERMIT(NCASS STCs) DSN(SYS3.NCPASS.*.PASSCAF) ACCESS(ALL) TSS PERMIT(<secaaudt>) DSN(SYS3.NCPASS.*.PASSCAF) ACCESS(U) TSS PERMIT(<audtaudt>) DSN(SYS3.NCPASS.*.PASSCAF) ACCESS(R) TSS PERMIT(<syspaudt>) DSN(SYS3.NCPASS.*.PASSVSDD) ACCESS(ALL) TSS PERMIT(<tstcaudt>) DSN(SYS3.NCPASS.*.PASSVSDD) ACCESS(ALL) TSS PERMIT(NCASS STCs) DSN(SYS3.NCPASS.*.PASSVSDD) ACCESS(ALL) TSS PERMIT(<secaaudt>) DSN(SYS3.NCPASS.*.PASSVSDD) ACCESS(U) TSS PERMIT(<audtaudt>) DSN(SYS3.NCPASS.*.PASSVSDD) ACCESS(R) Not_Reviewed Vuln_Num V-225594 Rule_ID SV-225594r1146097_rule Severity medium Rule_Title Quest NC-Pass will be used by highly sensitive users. Vuln_Discuss DISA has directed that Quest NC-Pass extended authentication be implemented on all domains. All users with WRITE and/or greater access to sensitive system-level data sets and resources, or who possess special security privileges, are required to use NC-Pass for extended authentication. Typical personnel required to use NC-Pass include, but are not limited to, systems programming, security, operations, network/communications, storage management, and production control. Improper enforcement of extended authentication through NC-Pass could potentially compromise the operating system, Access Control Program (ACP), and customer data. Check_Content Refer to the following reports produced by the TSS Data Collection and Data Set and Resource Data Collection: - TSSCMDS.RPT(@ACIDS). - TSSCMDS.RPT(@ALL). - SENSITVE.RPT(WHOHABS). If all sensitive users requiring NC-Pass validation has the NCPASS Facility and permitted to the SECURID resource in the ABSTRACT resource class, this is not a finding. Note: Sensitive users include systems programming personnel, security personnel, and other staff (e.g., DASD management, operations, auditors, technical support, etc.) with access to sensitive resources (e.g., operator commands, ACP privileges, etc.) that can modify the operating system and system software, and review/modify the security environment. Fix_Text The ISSO will ensure that sensitive users are properly validated to Quest NC-Pass. Note: Sensitive users include systems programming personnel, security personnel, and other staff (e.g., DASD management, operations, auditors, technical support, etc.) with access to sensitive resources (e.g., operator commands, ACP privileges, etc.) that can modify the operating system and system software, and review/modify the security environment. Sensitive users requiring access to NC-PASS must be granted access to the NCPASS Facility and the SECURID resource in the ABSTRACT resource class. Use the following commands as an example: TSS ADD(acid) FAC(NCPASS) TSS PERMIT(acid) ABS(SECURID) Not_Reviewed Vuln_Num V-225595 Rule_ID SV-225595r1146100_rule Severity medium Rule_Title Quest NC-Pass Started Task name will be properly identified and/or defined to the system ACP. Vuln_Discuss Quest NC-Pass 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. Check_Content Refer to the following report produced by the TSS Data Collection: - TSSCMDS.RPT(@ACIDS). Review Quest NC-Pass STC/Batch ACID(s). If the following attributes are defined, this is not a finding. FACILITY(STC, BATCH) PASSWORD(xxxxxxxx,0) SOURCE(INTRDR) NOSUSPEND MASTFAC(NCPASS) Fix_Text The ISSO working with the systems programmer will ensure the Quest NC-Pass Started Task(s) is properly identified and/or defined to the system ACP. If the product requires a Started Task, verify that it is properly defined to the system ACP with the proper attributes. Most installation manuals will indicate how the Started Task is identified and any additional attributes that must be specified. The following commands are provided as a sample for defining Started Task(s): TSS CREATE(NCPASS) TYPE(USER) - NAME('STC, Quest NC-Pass') DEPT(xxxx) - FAC(STC,BATCH) PASS(xxxxxxxx,0) - SOURCE(INTRDR) NOSUSPEND MASTFAC(NCPASS) Not_Reviewed Vuln_Num V-225596 Rule_ID SV-225596r1146103_rule Severity medium Rule_Title Quest NC-Pass Started task will be properly defined to the Started Task Table ACID for Top Secret. Vuln_Discuss 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. Check_Content Refer to the following report produced by the TSS Data Collection: - TSSCMDS.RPT(#STC). Automated Analysis Refer to the following report produced by the TSS Data Collection: - PDI(ZNCP0032).

Fix_Text The ISSO working with the systems programmer will ensure the Quest NC-Pass Started Task(s) is properly identified and/or defined to the system ACP.
