Issue Description

The Protection Profile for Virtualization Version 1.1 (PP_BASE_VIRTUALIZATION_V1.1.pdf) includes Evaluation Activities classified by TSS, Guidance and Test. There are several TSS evaluation activities where both TSS and guidance EAs are included; in some cases there is no Guidance section for that SFR.

Resolution

The TSS EA for FCS_IPSEC_EXT.1.3 in PP_BASE_VIRTUALIZATION_V1.1 is modified as follows, with red highlighted strikethrough denoting deletion and green highlighted underline denoting addition:

 

TSS

If both transport mode and tunnel mode are implemented, the evaluator shall review the

 

operational guidance to determine how the use of a given mode is specified.

The evaluator shall examine the TSS  to verify that the TSS provides a description of how a packet is

processed against the SPD and that if no “rules” are found to match, that a final rule exists, either implicitly

or explicitly, that causes the network packet to be discarded.

 

The TSS and Guidance EAs for FIA_UIA_EXT.1 is modified as follows, with red highlighted strikethrough denoting deletion and green highlighted underline denoting addition:

 

TSS

The evaluator shall examine the TSS to determine that it describes the logon process for each

logon method (local, remote (HTTPS, SSH, etc.)) supported for the product. This description

shall contain information pertaining to the credentials allowed/used, any protocol transactions

that take place, and what constitutes a “successful logon.” The evaluator shall examine the

operational guidance to determine that any necessary preparatory steps (e.g., establishing

credential material such as pre-shared keys, tunnels, certificates) to logging in are described.

For each supported login method, the evaluator shall ensure the operational guidance provides

clear instructions for successfully logging on. If configuration is necessary to ensure the services

provided before login are limited, the evaluator shall determine that the operational guidance

provides sufficient instruction on limiting the allowed services.

 

Guidance

The evaluator shall examine the operational guidance to determine that any necessary preparatory

steps (e.g., establishing credential material such as pre-shared keys, tunnels, certificates) to logging

in are described. For each supported login method, the evaluator shall ensure the operational

guidance provides clear instructions for successfully logging on. If configuration is necessary to ensure

the services provided before login are limited, the evaluator shall determine that the operational guidance

provides sufficient instruction on limiting the allowed services.

 

 

The Guidance EA for FIA_X509_EXT.2 is added as follows, with green highlighted underline denoting addition:

 

Guidance

The evaluator shall ensure that the guidance documentation describes the

configuration required in the operating environment so the TOE can use the

certificates. The guidance documentation shall also include any required

configuration on the TOE to use the certificates. The guidance documentation shall

also describe the steps for the Security Administrator to follow if the

connection cannot be established during the validity check of a certificate used

in establishing a trusted channel.

 

 

The TSS and Guidance EAs for FPT_ML_EXT.1 are modified as follows, with red highlighted strikethrough denoting deletion and green highlighted underline denoting addition:

 

TSS

The evaluator shall verify that the TSS or Operational Guidance describes how integrity

measurements are performed and made available to the Management Subsystem. The evaluator

shall examine the operational guidance to verify that it documents how to access the

measurements in the Management Subsystem.

 

Guidance

 The evaluator shall examine the operational guidance to verify that it documents how to access the

measurements in the Management Subsystem.
