Issue Description

It is unclear that individual events in Table 3 can be selected in FAU_GEN.1 without including the entirety of Table 3.  Additionally, several auditable events are being made optional.


 07/30/2019: This TD has been archived and superseded by TD0431.


The following changes shall be made to the Virtualization PP (PP_BASE_VIRTUALIZATION_V1.0)




1. Add the bold text below to the Application Note for FAU_GEN.1: Audit Data Generation




Application Note:            The ST author can include other auditable events directly in Table 1; they are not limited to the list presented. The ST author should update the table in FAU_GEN.1.2 with any additional information generated. “Subject identity” in FAU_GEN.1.2 could be a user id or an identifier specifying a VM, for example.


If ‘additional information defined in Table 3’ is selected, it is acceptable to include individual entries from Table 3 without including the entirety of Table 3.  Appropriate entries from Tables 2, 4, and 5 should be included in the ST if the associated SFRs and selections are included.


The Table 1 entry for FDP_VNC_EXT.1 refers to configuration settings that attach VMs to virtualized network components. Changes to these configurations can be made during VM execution or when VMs are not running. Audit records must be generated for either case.


The intent of the audit requirement for FDP_PPR_EXT.1 is to log that the VM is connected to a physical device (when the device becomes part of the VM’s hardware view), not to log every time that the device is accessed. Generally, this is only once at VM startup. However, some devices can be connected and disconnected during operation (e.g., virtual USB devices such as CD-ROMs). All such connection/disconnection events must be logged.




2. Change the text in Annex B immediately preceding Table 3 from:


The following additional auditable events shall be claimed by the ST author if “additional information defined in Table 3” is selected in FAU_GEN.1:




The following additional auditable events may be claimed by the ST author if “additional information defined in Table 3” is selected in FAU_GEN.1.  Any subset of Table 3, including individual entries, may be included in the ST; it is not necessary to include the entirety of Table 3.




3. Move the following auditable event entries to Table 3 in Annex B:


FCS_HTTPS_EXT.1 (from Table 4)


FCS_TLSC_EXT.1 (from Table 4)


FCS_TLSS_EXT.2 (from Table 4)


FCS_TLSC_EXT.2 (from Table 4 as added in TD 213)


FCS_TLSS_EXT.1 (from Table 4 as added in TD 213)




These changes clarify FAU_GEN.1 and give the ST author additional auditing flexibility.
