Foreword
The Netherlands Scheme for Certification in the Area of IT Security (NSCIB) provides a third-party
evaluation and certification service for determining the trustworthiness of Information Technology (IT)
security products. Under this NSCIB, TÜV Rheinland Nederland B.V. has the task of issuing
certificates for IT security products, as well as for protection profiles and sites.
Part of the procedure is the technical examination (evaluation) of the product, protection profile or site
according to the Common Criteria assessment guidelines published by the NSCIB. Evaluations are
performed by an IT Security Evaluation Facility (ITSEF) under the oversight of the NSCIB Certification
Body, which is operated by TÜV Rheinland Nederland B.V. in cooperation with the Ministry of the
Interior and Kingdom Relations.
An ITSEF in the Netherlands is a commercial facility that has been licensed by TÜV Rheinland
Nederland B.V. to perform Common Criteria evaluations; a significant requirement for such a license is
accreditation to the requirements of ISO Standard 17025 “General requirements for the accreditation
of calibration and testing laboratories”.
By awarding a Common Criteria certificate, TÜV Rheinland Nederland B.V. asserts that the product or
site complies with the security requirements specified in the associated (site) security target, or that
the protection profile (PP) complies with the requirements for PP evaluation specified in the Common
Criteria for Information Security Evaluation. A (site) security target is a requirements specification
document that defines the scope of the evaluation activities.
The consumer should review the (site) security target or protection profile, in addition to this
certification report, in order to gain an understanding of any assumptions made during the evaluation,
the IT product's intended environment, its security requirements, and the level of confidence (i.e., the
evaluation assurance level) that the product or site satisfies the security requirements stated in the
(site) security target.

Recognition of the certificate
Presence of the Common Criteria Recognition Arrangement and SOG-IS logos on the certificate
indicates that this certificate is issued in accordance with the provisions of the CCRA and the SOG-IS
agreement and will be recognised by the participating nations.
International recognition
The CCRA has been signed by the Netherlands in May 2000 and provides mutual recognition of
certificates based on the CC. Starting September 2014 the CCRA has been updated to provide mutual
recognition of certificates based on cPPs (exact use) or STs with evaluation assurance components
up to and including EAL2+ALC_FLR. The current list of signatory nations and approved certification
schemes can be found on: http://www.commoncriteriaportal.org.
European recognition
The European SOGIS-Mutual Recognition Agreement (SOGIS-MRA) version 3 effective from April
2010 provides mutual recognition of Common Criteria and ITSEC certificates at a basic evaluation
level for all products. A higher recognition level for evaluation levels beyond EAL4 (resp. E3-basic) is
provided for products related to specific technical domains. This agreement was initially signed by
Finland, France, Germany, The Netherlands, Norway, Spain, Sweden and the United Kingdom. Italy
joined the SOGIS-MRA in December 2010. The current list of signatory nations, approved certification
schemes and the list of technical domains for which the higher recognition applies can be found on:

1 Executive Summary
This Certification Report states the outcome of the Common Criteria security evaluation of the
Youwipe Erasure Tool 4 with WipeCenter 4. The developer of the Youwipe Erasure Tool 4 with
WipeCenter 4 is AllWipe Ltd located in Katajaranta, Finland and they also act as the sponsor of the
evaluation and certification. A Certification Report is intended to assist prospective consumers when
judging the suitability of the IT security properties of the product for their particular requirements.
The TOE consists of two main components Youwipe Data Erasure Tool (further referred to as
Youwipe tool) and WipeCenter report management application (further referred to as WipeCenter
application).
The Youwipe tool is performing the secure erasure actions (in line with the selected standard), as well
as verification of erasure results and issuing of the erasure report. The Youwipe tool includes all the
tools and drivers needed for its interaction with other hardware elements on the host machine.
The WipeCenter application is responsible for regulating the access to the generated erasure reports.
The application allows users to read or delete erasure reports stored on a local server.
The TOE has been evaluated by Secura B.V. located in Amsterdam, The Netherlands. The evaluation
was completed on 12 August 2020 with the approval of the ETR. The certification procedure has been
conducted in accordance with the provisions of the Netherlands Scheme for Certification in the Area of
IT Security [NSCIB].
The scope of the evaluation is defined by the security target [ST], which identifies assumptions made
during the evaluation, the intended environment for the Youwipe Erasure Tool 4 with WipeCenter 4,
the security requirements, and the level of confidence (evaluation assurance level) at which the
product is intended to satisfy the security requirements. Consumers of the Youwipe Erasure Tool 4
with WipeCenter 4 are advised to verify that their own environment is consistent with the security
target, and to give due consideration to the comments, observations and recommendations in this
certification report.
The results documented in the evaluation technical report [ETR]
1
for this product provides sufficient
evidence that the TOE meets the EAL3 augmented (EAL3+) assurance requirements for the evaluated
security functionality. This assurance level is augmented with ALC_FLR.1 (Flaw remediation).
The evaluation was conducted using the Common Methodology for Information Technology Security
Evaluation, Version 3.1 Revision 5 [CEM] for conformance to the Common Criteria for Information
Technology Security Evaluation, version 3.1 Revision 5 [CC].
TÜV Rheinland Nederland B.V., as the NSCIB Certification Body, declares that the evaluation meets
all the conditions for international recognition of Common Criteria Certificates and that the product will
be listed on the NSCIB Certified Products list. It should be noted that the certification results only apply
to the specific version of the product as evaluated.

The erasure standards chosen for evaluation are:
• EXT. HMG Infosec High for HDD, SDD, Flash drives, SD cards;
• Infosec High for Android devices;
• Cryptographic Erasure for iOS devices.
The WipeCenter application is responsible for:
• Enforcing authentication for the access of erasure reports generated by the Erasure Engine of
Youwipe, while at the same time collecting information about modifications to existing users
and failed authentication attempts;
• Ensuring role separation in the access of erasure report (separation between read-only rights
and read-only + delete rights);
• Retrieving the erasure report from the local server and verifying its integrity;
• Deleting erasure reports from the local server;
• Generating new passwords for existing users.
2.3 Assumptions and Clarification of Scope
2.3.1 Assumptions

Identifier Version
Youwipe Erasure Tool User Manual 2.0.6
WipeCenter User Manual 2.0.5
2.6 IT Product Testing
Testing (depth, coverage, functional tests, independent testing): The evaluators examined the
developer’s testing activities documentation and verified that the developer has met their testing
responsibilities.
2.6.1 Testing approach and depth
The developer performed testing against the functional specification, covering all TSFI and (implicitly)
all subsystems. The developer testing included both positive and negative test cases.
For the testing performed by the evaluators, the developer has provided a test environment. The
evaluators have reproduced a selection of (14) the developer tests, selected based on the following
criteria:
• Criticality of the tests;
• Depth of provided test evidence.
The evaluator designed (5) additional test cases to further investigate some areas of functionality.
2.6.2 Independent Penetration Testing
AVA testing was performed in the following steps:
• Analysis of publicly known vulnerabilities (initial research with Google for each of the
components of the TOE, followed by research within the CVE database and research within
the web-site of the component’s developer);
• Attempting to exploit identified applicable publicly known vulnerabilities;
• Performing additional independent testing based on the developed test plan of (18)
penetration test cases.
A total of 32 days testing effort was applied to the logical testing, of which 25 days were spent on
penetration testing.
2.6.3 Test Configuration
The test configuration used was in accordance with the evaluated configuration, using the following
components:
• Data Eraser Tool;
• PC Hard drive x2
• SSD
• USB
• Android phone – Samsung A10
• iPHONE 5S
All tests were performed on the initially supplied versions (WipeCenter version 4.0.32, YouWipe
version 4.1.41), with as exceptions:
• Tests which resulted in an update being issued were repeated on the updated version to verify
correctness and sufficiency of the patch;

• Tests that cover TSFI that may unwillingly be impacted by changes made to other
components in order to address (seemingly unrelated) issues in the TOE.
In addition to basic Ubuntu system utilities (grep, strings, awk, base64, curl, tar, openssl, nc, etc.), a
number of specialised tools were used throughout the technical part of this evaluation, including
forensic, web application assessment, network assessment and reverse engineering tools.
2.6.4 Testing Results
The testing activities, including configurations, procedures, test cases, expected results and observed
results are summarised in the [ETR], with references to the documents containing the full details.
The developer’s tests and the independent functional tests produced the expected results, giving
assurance that the TOE behaves as specified in its [ST] and functional specification.
No exploitable vulnerabilities were found with the independent penetration tests.
2.7 Re-used evaluation results
There is no re-use of evaluation results in this certification.
2.8 Evaluated Configuration
The TOE is defined uniquely by its name and version number Youwipe Erasure Tool 4 with
WipeCenter 4.
2.9 Results of the Evaluation
The evaluation lab documented their evaluation results in the [ETR] which references a ASE
Intermediate Report and other evaluator documents.
The verdict of each claimed assurance requirement is “Pass”.
Based on the above evaluation results the evaluation lab concluded the Youwipe Erasure Tool 4 with
WipeCenter 4, to be CC Part 2 extended, CC Part 3 conformant, and to meet the requirements of
EAL 3 augmented with ALC_FLR.1. This implies that the product satisfies the security requirements
specified in Security Target [ST].
2.10 Comments/Recommendations
The user guidance as outlined in section 2.5 contains necessary information about the usage of the
TOE.
In addition all aspects of assumptions, threats and policies as outlined in the Security Target not
covered by the TOE itself need to be fulfilled by the operational environment of the TOE.
The customer or user of the product shall consider the results of the certification within his system risk
management process. In order for the evolution of attack methods and techniques to be covered, he
should define the period of time until a re-assessment for the TOE is required and thus requested from
the sponsor of the certificate.
