The Mother of All NIAP Protection Profiles – NDcPP

Lachlan TurnerCertifications, Common Criteria

We took a strategic decision early on at Lightship Security to focus our initial Greenlight development efforts on automating the tests specified by the Network Device collaborative Protection Profile (NDcPP). There are two main reasons for this:

  1. It is the most widely used Common Criteria Protection Profile in North America (given its generic applicability)
  2. It is the forerunner for most NIAP Approved Protection Profiles which re-use a large portion of the NDcPP Security Functional Requirements (SFRs)

Now, we have automated the testing not only for NDcPP but also several other Protection Profiles by virtue of this SFR re-use.  Below we present an analysis of the re-use of NDcPP requirements across NIAP Approved Protection Profiles (all but a few).

Notable NDcPPv2.1 Changes (from v2.0e)

Lachlan TurnerCertifications, Common Criteria

[March 12, 2019 Update] NDcPPv2.1 has been formally endorsed by NIAP.

NDcPPv2.1 is hot off the presses from the Network iTC.  It is yet to be officially accepted by NIAP for PCL usage however this is probably not too far off, perhaps with some minor tweaks (the new NTP SFR being something to watch).

Here are some notes from our initial review:

  • NTP. A new SFR has been added for NTP which we understand refers to mechanisms that are supported by commonly available NTP clients.  Vendors still have the option of specifying manual time configuration. If v2.1 is accepted by NIAP as is, this will remove the mandated use of a trusted channel for NTP which was causing problems for some vendors in v2.0e.
  • TLS. Administrators can now elect to ignore certificate validation failures. Support for 192-bit ciphersuites has been removed and a couple of new suites have been added.
  • X.509. Certificate revocation checking requirements have been ‘clarified’ by an application note. This may result in changes for implementations that meet the current requirements.
  • Audit Events. All generation/import/change of long-term cryptographic keys (i.e. not session keys) need to be audited, including those that are automatically generated by the TOE.

SSH Rekey Limits with OpenSSH

Greg McLearnCommon Criteria

Since this article was posted, the international Network Interpretations Team has issued RFI 201824 stating that the send and receive keys can be independently rekeyed.  Therefore, the requirement that the ‘aggregate’ traffic be counted is no longer mandated according to the iTC.  NIAP has yet to endorse RFI 201824, meaning that still, as of April 2, 2019, NIAP still requires the aggregate be counted.

Background

In the current version of the NDcPP there is a cryptographic Security Functional Requirement (SFR) called FCS_SSH*_EXT.1.8.  On the face of it, FCS_SSH*_EXT.1.8 is a fairly straightforward SFR with a relatively straightforward means to enforce it:

FCS_SSHS_EXT.1.8: The TSF shall ensure that within SSH connections the same session keys are used for a threshold of no longer than one hour, and no more than one gigabyte of transmitted data. After either of the thresholds are reached a rekey needs to be performed.

However, it is vitally important to read the application note (Application Note 102 in NDcPP v2.0+20180314) that follows this SFR element, because one small detail appears to be catching vendors by surprise:

For the maximum transmitted data threshold, the total incoming and outgoing data needs to be counted.

Don’t Call it a Bash Script: Automation is Not Scripting

Alex ThurstonCertifications, Common Criteria

Or, maybe it is.  In reality, the answer is that all automation is scripting but not all scripting is automation.  Automation is really a maturation or evolution of scripting.  Calculators script the mathematical principles defined by Thales, Pythagoras, Euclid and Archimedes.  To-do applications script the act of making a list of tasks on a piece of paper and scratching them off.  The directions given by Google Maps on a road trip script the job normally performed by the person with a paper map sitting in the passenger seat.

How to get on the NIAP Product Compliant List (PCL)

Lachlan TurnerCertifications, Common Criteria

Many vendors seeking to sell hardware or software to the U.S. Government, particularly to defense and intelligence agencies, will find that cyber security product certification is mandated by federal procurement requirements (CNSSP 11) for these environments. We know, because many of our clients come to us for this very reason – fast, efficient, low risk evaluations that ultimately end up on the National Information Assurance Partnership (NIAP) Product Compliant List (PCL).
