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.
Checks: C-27292r472575_chk

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 restricts READ access to all authorized users. ___ The TSS data set rules for the data sets restricts 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: F-27280r472576_fix

The IAO will ensure that WRITE and/or greater access to Quest NC-Pass installation data sets is limited to System 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. He will identify if any additional groups have WRITE and/or greater access for specific data sets, and once documented he will work with the IAO to see that they are properly restricted to the ACP (Access Control Program) active on the system. Data sets to be protected will be: SYS2.NCPASS. SYS3.NCPASS. (data sets that are not altered by product STCs, can be more specific) The following commands are provided as a sample for implementing data set controls: TSS PERMIT(<syspaudt>) DSN(SYS2.NCPASS.) ACCESS(R) TSS PERMIT(<syspaudt>) DSN(SYS2.NCPASS.) ACCESS(ALL) ACTION(AUDIT) TSS PERMIT(<tstcaudt>) DSN(SYS2.NCPASS.) ACCESS(R) TSS PERMIT(<tstcaudt>) DSN(SYS2.NCPASS.)

DISA has directed that Quest NC-Pass extended authentication be implemented on all domains. All users with update and alter 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, ACP, and customer data.

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: F-27282r472582_fix

The IAO 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)

Quest NC-Pass requires a started task that will be restricted to certain resources, datasets and other system functions. By defining the started task as a userid to the system ACP, It allows the ACP to control the access and authorized users that require these capabilities. Failure to properly control these capabilities, could compromise of the operating system environment, ACP, and customer data.
Checks: C-27295r472584_chk

Refer to the following report produced by the TSS Data Collection: - TSSCMDS.RPT(@ACIDS) Verify that the ACID(s) for the Quest NC-Pass started task(s) is (are) properly defined.
