PRODUCT TESTING
The independent testing approach has been testing all the SFRs declared in the Security Target, all
the TSFIs declared in the Functional Specification and all the subsystems declared in the TOE
Design.
Regarding the repetition of the developer’s functional tests, the 54% of the tests have been
repeated. The developer’s functional tests are broken into three types corresponding to the
interface tested: Touchscreen, Remote Access and CashControl. The evaluator has repeated all
tests for Touchscreen and CashControl interfaces. The tests related to Remote Access interface was
not repeated because the functionality provided is the same than the provided by Touchscreen
interface, excluding the cash-related functionality that cannot be tested through Remote Access
interface, and they only can be tested through the Touchscreen interface.
On the other hand, the vulnerability analysis approach has been based in:
• Search of public vulnerabilities for the TOE components and the third-party libraries used by
the TOE.
• Search of public vulnerabilities for the OS where the TOE runs and for the SSH server of the
OS where the TOE runs.
• Identification of possible vulnerabilities in the Security Target, Guidance documentation,
Functional Specification, TOE Design and Security Architecture evidences.
Based on the vulnerabilities found, the evaluator calculated the attack potential and designed a test
for each vulnerability with Basic attack potential.
EVALUATED CONFIGURATION
The TOE evaluated version is ZEN-D v1.2.14.15 + OpenVPN v2.4.4, and the evaluated configuration
is:
• NTP is used to synchronize date and time through an external server. It is configured by
default by the manufacturer.

RECOGNITION AGREEMENTS
In order to avoid multiple certification of the same product in different countries a mutual
recognition of IT security certificates - as far as such certificates are based on ITSEC or CC - under
certain conditions was agreed.
European Recognition of ITSEC/CC – Certificates (SOGIS-MRA)
The SOGIS-Mutual Recognition Agreement (SOGIS-MRA) Version 3 became effective in April 2010. It
defines the recognition of certificates for IT-Products at a basic recognition level and, in addition, at
higher recognition levels for IT-Products related to certain SOGIS Technical Domains only.
The basic recognition level includes Common Criteria (CC) Evaluation Assurance Levels EAL 1 to EAL
4 and ITSEC Evaluation Assurance Levels E1 to E3 (basic). For "Smartcards and similar devices" a
SOGIS Technical Domain is in place. For "HW Devices with Security Boxes" a SOGIS Technical
Domains is in place, too. In addition, certificates issued for Protection Profiles based on Common
Criteria are part of the recognition agreement.
The new agreement has been signed by the national bodies of Austria, Finland, France, Germany,
Italy, The Netherlands, Norway, Spain, Sweden and the United Kingdom. The current list of
signatory nations and approved certification schemes, details on recognition, and the history of the
agreement can be seen on the website at https://www.sogis.eu.
The SOGIS-MRA logo printed on the certificate indicates that it is recognised under the terms of this
agreement by the nations listed above.
The certificate of this TOE is recognized under SOGIS-MRA for all assurance components selected.
International Recognition of CC – Certificates (CCRA)
The international arrangement on the mutual recognition of certificates based on the CC (Common
Criteria Recognition Arrangement, CCRA-2014) has been ratified on 08 September 2014. It covers
CC certificates based on collaborative Protection Profiles (cPP) (exact use), CC certificates based on
assurance components up to and including EAL 2 or the assurance family Flaw Remediation
(ALC_FLR) and CC certificates for Protection Profiles and for collaborative Protection Profiles (cPP).
The CCRA-2014 replaces the old CCRA signed in May 2000 (CCRA-2000). Certificates based on CCRA-
2000, issued before 08 September 2014 are still under recognition according to the rules of CCRA-

2000. For on 08 September 2014 ongoing certification procedures and for Assurance Continuity
(maintenance and re-certification)of old certificates a transition period on the recognition of
certificates according to the rules of CCRA-2000 (i.e. assurance components up to and including EAL
4 or the assurance family Flaw Remediation (ALC_FLR)) is defined until 08 September 2017.
As of September 2014 the signatories of the new CCRA-2014 are government representatives from
the following nations: Australia, Austria, Canada, Czech Republic, Denmark, Finland, France,
Germany, Greece, Hungary, India, Israel, Italy, Japan, Malaysia, The Netherlands, New Zealand,
Norway, Pakistan, Republic of Korea, Singapore, Spain, Sweden, Turkey, United Kingdom, and the
