1 Executive Summary
Target of Evaluation (TOE) and subject of the Security Target (ST) [6] is the
Security IC with a Machine Readable Travel Document, Basic Access Control
Application“ TCOS Passport Version 1.01 / P5CT072 and TCOS Passport
Version 1.01 / SLE66CLX641P.
The Security Target is based on the Common Criteria Protection Profile
Machine Readable Travel Document with „ICAO Application", Basic Access
Control [8].
The TOE is the contactless integrated circuit chip of machine readable travel
documents (MRTD’s chip) programmed according to the Logical Data Structure
(LDS) [15] and providing the Basic Access Control according to ICAO document
[14]. It will be embedded as an inlay chip module into a passport booklet.
The TOE comprises
• the circuitry of the MRTD’s chip (the integrated circuit, IC) with hardware for
the contactless interface, e.g. antennae, capacitors
• the IC Dedicated Software with the parts IC Dedicated Test Software and IC
Dedicated Support Software
• the IC Embedded Software (operating system TCOS)
• the MRTD application (dedicated file for the ICAO application in a file system
on the chip and
• the associated guidance documentation.
The TOE is a Smart Device with an operating system (TCOS) and a dedicated
file-system, that contains all data relevant for the ICAO application.
For details on the MRTD chip and IC Dedicated Software see certification
reports BSI-DSZ-CC-0312-2005 [12] for the Philips chip P5CT072V0N and BSI-
DSZ-CC-0338-2005 [13] for the Infineon chip SLE66CLX641P.
Following the protection profile PP0002 [11, Fig. 15] the life cycle phases of a
TCOS Passport device can be divided into the following seven phases:
• Phase 1: Development of operating system software by the operating
system manufacturer
• Phase 2: Development of the smart card controller by the semiconductor
manufacturer
• Phase 3: Fabrication of the smart card controller (integrated circuit) by the
semiconductor manufacturer
• Phase 4: Installation of the chip in an inlay with an antenna
• Phase 5: Completion of the smart card operating system
• Phase 6: Initialisation and personalization of the MRTD
B-3
Certification Report BSI-DSZ-CC-0316-2005
• Phase 7: Operational phase of the MRTD
According to the MRTD BAC PP [8] the TOE life cycle is described in terms of
the four life cycle phases.
• Life cycle phase 1 “Development”: Development of Hardware and Software.
This life cycle phase 1 covers Phase 1 and Phase 2 of PP0002 [11]. 8
• Life cycle phase 2 “Manufacturing”: IC Production, Initialisation and Pre-
Personalization of the MRTD Application. This life cycle phase 2
corresponds to Phase 3 and Phase 4 of PP0002 [11] and may include for
flexibility reasons Phase 5 and some production processes from Phase 6
as well. 9
• Life cycle phase 3 “Personalization of the MRTD”: This life cycle phase
corresponds to the remaining initialisation and personalization processes
not covered yet from Phase 6 of the PP0002 [11].
• Life cycle phase 4 “Operational Use”. This life cycle phase corresponds to
the Phase 7 of the PP0002 [11].
The TOE is finished after initialisation, testing the OS and creation of the
dedicated file system with security attributes and ready made for the import of
LDS. This corresponds to the end of life cycle phase 2 of the Protection Profile
MRTD BAC PP [8]. A more detailed description of the production processes in
Phases 5 and 6 of PP0002 resp. Phase 3 of the MRTD BAC PP is given in the
Administrator Guidance document [16].

1.4 Summary of threats and Organisational Security Policies (OSPs)
addressed by the evaluated IT product
The ST defines the following assets taken from the MRTD BAC PP [8]:
Logical MRTD Data consisting of the data groups DG1 to DG16 and the
Document security object according to LDS [15].
Authenticity of the MRTD’s chip
Assets have to be protected in terms of confidentiality and/or integrity.
The ST considers the following subjects taken from the MRTD BAC PP [8]:
Manufacturer, MRTD Holder, Traveller, Personalization Agent, Inspection
System (split into Primary Inspection System (PIS), Basic Inspection System
(BIS), and Extended Inspection System (EIS)), the Terminal and the Attacker.
For details refer to the Security Target chapter 3.2.
The following list of considered threats for the TOE is defined in the Security
Target. They are taken from the MRTD BAC PP [8].
T.Chip_ID Identification of MRTD’s chip
An attacker trying to trace the movement of the MRTD by identifying remotely
the MRTD’s chip by establishing or listening a communication through the
contactless communication interface. The attacker can not read and does not
know in advance the MRZ data printed on the MRTD data page.
T.Skimming Skimming the logical MRTD
An attacker imitates the inspection system to read the logical MRTD or parts of
it via the contactless communication channel of the TOE. The attacker can not
B-8
BSI-DSZ-CC-0316-2005 Certification Report
read and does not know in advance the MRZ data printed on the MRTD data
page.
T.Eavesdropping Eavesdropping to the communication between TOE and
inspection system
An attacker is listening to the communication between the MRTD’s chip and an
inspection system to gain the logical MRTD or parts of it. The inspection system
uses the MRZ data printed on the MRTD data page but the attacker does not
know this data in advance.
T.Forgery Forgery of data on MRTD’s chip
An attacker alters fraudulently the complete stored logical MRTD or any part of
it including its security related data in order to impose on an inspection system
by means of the changed MRTD holder’s identity or biometric reference data.
This threat comprises several attack scenarios of MRTD forgery.
T.Abuse-Func Abuse of Functionality
An attacker may use functions of the TOE which shall not be used in TOE
operational phase in order (i) to manipulate User Data, (ii) to manipulate
(explore, bypass, deactivate or change) security features or functions of the
TOE or (iii) to disclose or to manipulate TSF Data. This threat addresses the
misuse of the functions for the initialisation and the personalization in the
operational state after delivery to MRTD holder.
T.Information_Leakage Information Leakage from MRTD’s chip
An attacker may exploit information which is leaked from the TOE during its
usage in order to disclose confidential TSF data. The information leakage may
be inherent in the normal operation or caused by the attacker.
T.Phys-Tamper Physical Tampering
An attacker may perform physical probing of the MRTD’s chip in order to
disclose TSF Data to disclose/reconstruct the MRTD’s chip Embedded
Software. An attacker may physically modify the MRTD’s chip in order to (i)
modify security features or functions of the MRTD’s chip, (ii) modify security
functions of the MRTD’s chip Embedded Software, (iii) to modify User Data or
(iv) to modify TSF data.
T.Malfunction Malfunction due to Environmental Stress
An attacker may cause a malfunction of TSF or of the MRTD’s chip Embedded
Software by applying environmental stress in order to (i) deactivate or modify
security features or functions of the TOE or (ii) circumvent or deactivate or
modify security functions of the MRTD’s chip Embedded Software.
For more details refer to the Security Target chapter 3.3.
The TOE shall comply to the following organisation security policies as security
rules, procedures, practices, or guidelines imposed by an organisation upon its
operations:
B-9
Certification Report BSI-DSZ-CC-0316-2005
P.Manufact Manufacturing of the MRTD’s chip
The IC Manufacturer and MRTD Manufacturer ensure the quality and the
security of the manufacturing process and control the MRTD’s material in the
Phase 2 Manufacturing. The Initialisation Data are written by the IC
Manufacturer to identify the IC uniquely. The MRTD Manufacturer writes the
Pre-personalization Data which contains at least the Personalization Agent Key.
P.Personalization Personalization of the MRTD by issuing State or
Organisation only
The issuing State or Organisation guarantees the correctness of the
biographical data, the printed portrait and the digitised portrait, the biometric
reference data and other data of the logical MRTD with respect to the MRTD
holder. The personalization of the MRTD for the holder is performed by
authorised agents of the issuing State or Organisation only.
P.Personal_Data Personal data protection policy
The biographical data and their summary printed in the MRZ and stored on the
MRTD’s chip (DG1), the printed portrait and the digitised portrait (DG2), the
biometric reference data of finger(s) (DG3), the biometric reference data of iris
image(s) (DG4) and data according to LDS (DG5 to DG14, DG16) stored on the
MRTD’s chip are personal data of the MRTD holder. These data groups are
intended to be used only with agreement of the MRTD holder by inspection
systems to which the MRTD is presented. The MRTD’s chip shall provide the
possibility for the Basic Access Control to allow read access to these data only
for terminals successfully authenticated based on knowledge of the Document
Basic Access Keys as defined in [14].
1.5 Special configuration requirements
The issuing State or Organisation decides (i) to enable the Basic Access
Control for the protection of the MRTD holder personal data or (ii) to disable the
Basic Access Control to allow Primary Inspection Systems of the receiving
States and all other terminals to read the logical MRTD. This configuration is
performed during the personalization phase 3 of the TOE life cycle.
1.6 Assumptions about the operating environment
The assumptions are describe the security aspects of the environment in which
the TOE will be used or is intended to be used. The ST defines the following
assumptions taken from the MRTD BAC PP [8]:
A.Pers_Agent Personalization of the MRTD’s chip
The Personalization Agent ensures the correctness of (i) the logical MRTD with
respect to the MRTD holder, (ii) the Document Basic Access Keys, (iii) the
Active Authentication Public Key Info (DG15) if stored on the MRTD’s chip, and
(iv) the Document Signer Public Key Certificate (if stored on the MRTD’s chip)
on the MRTD’s chip. (Note: Because the Active Authentication Public Key Info
(DG15) is not stored on the TOE, this assumption from the MRTD BAC PP [8] is
B-10
BSI-DSZ-CC-0316-2005 Certification Report
not relevant.) The Personalization Agent signs the Document Security Object.
The Personalization Agent bears the Personalization Agent Authentication to
authenticate himself to the TOE by symmetric cryptographic mechanisms.
A.Insp_Sys Inspection Systems for global interoperability
The Inspection System is used by the border control officer of the receiving
State (i) examining an MRTD presented by the traveller and verifying its
authenticity and (ii) verifying the traveller as MRTD holder. The Primary
Inspection System for global interoperability contains the Country Signing Public
Key and the Document Signer Public Key of each issuing State or Organisation
[14]. The Primary Inspection System performs the Passive Authentication to
verify the logical MRTD if the logical MRTD is not protected by Basic Access
Control. The Basic Inspection System in addition to the Primary Inspection
System implements the terminal part of the Basic Access Control and reads the
logical MRTD being under Basic access Control.

Table 5: Deliverables of the TOE
The TOE is finalized at the end of phase 2 according to the MRTD BAC PP.
Delivery is performed from the Initialization facility to the personalisation facility
by as a secured transport to a specific person of contact at the personalization
site. Furthermore, the personalizer receives information about the
personalisation commands and process requirements. To ensure that the
personalizer receives this evaluated version, the procedures to start the
personalisation process as described in the administrator manual [16] have to
be followed. Within this evaluation initialisation and personalization organisation
were the same organisation and facility (Bundesdruckerei, Berlin, Germany).
3 Security Policy
The security policy of the TOE is defined according to the MRTD BAC PP [8] by
the security objectives and requirements for the contactless chip of machine
readable travel documents (MRTD) based on the requirements and
recommendations of the International Civil Aviation Organisation (ICAO). It
addresses the advanced security methods Basic Access Control in the
Technical reports of the ICAO New Technology Working Group.
4 Assumptions and Clarification of Scope
The assumptions on Personalization of the MRTD’s chip and on Inspection
Systems for global interoperability as outlined above are of relevance.
The state or organisation issues the MRTD to be used by the holder for
international travel. The traveller presents a MRTD to the inspection system to
prove his or her identity. The authentication of the traveller is based on (i) the
possession of a valid MRTD personalized for a holder with the claimed identity
as given on the biographical data page and (ii) biometrics using the reference

DSZ-CC-0338-2005 [13] for the Infineon chip SLE66CLX641P.

data stored in the MRTD. The issuing State or Organisation ensure the
authenticity of the data of genuine MRTD’s. The receiving State trust a genuine
MRTD of a issuing State or Organisation.
5 Architectural Information
The TOE consists of hardware and software. Hardware is either the Infineon
Chip SLE66CX641P or the Philips Chip P5CT072V0N.
The TOE software is the chip card operation system TCOS and the specific
ICAO file-system specified by specific initialisation data. The software is
grouped as follows:
The kernel subsystem controls the communication between all other
subsystems. It checks the used memory areas, allocates resources and
controls the order of operation.
The administrative subsystem contains all administrative functionality of the
TOE. It provides functionality for generation and deletion of files and directories
and for reading and writing of files. This subsystem is also responsible for
access control.
The crypto subsystem contains the cryptographic functionality and guarantees
controlled access to keys.
The IO subsystem is responsible for all communication to the external world. It
implements the protocol T=CL and checks syntax of APDUs.
The ROM TCOS-Type Task includes the ISO specific parts of the code. It
analysis the APDUs and enforces calls to other subsystems.
The User-Type Task of TCOS including application specific code but is not used
within the TOE.
The TSF of the software uses the hardware via evaluated hardware interfaces.
External interface of the composite TOE used in the MRTD application is a
specific set of commands operating on a defined file-system of the application.
This interface is available to the inspection system via the contactless chip
interface.
6 Documentation
The administrator manual [16] is provided for the Personalization Agent of the
TOE who needs information about security procedures and how the TOE
supports the personalisation process. In addition this documents includes
information about the initialisation process which is done before TOE delivery.
In this case initialisation and personalization is performed by the same
organisation (Bundesdruckerei, Berlin, Germany).
The user manual [17] is provided for the developer of an inspection system who
needs information how the TOE interacts with the inspection system.

7 IT Product Testing
Developer tests, independent evaluator tests and penetration tests were
performed using MRTD chips TCOS Passport Version 1.01/P5CT072 (Philips
Chip) and TCOS Passport Version 1.01/SLE66CLX641P (Infineon Chip)
composed of the hardware chip, its dedicated software, the operating system
TCOS and a file-system for the ICAO application. TOEs in the configuration
LDS (Logical Data Structure) and BAC (Basic Access Control) were tested.
The developer performed functional tests with a TOE in the personalization
phase and in the operational phase. All security functions were tested including
their sub-functions. The test coverage analysis and the test depth analysis gave
evidence that the TOE was systematically tested on the level of the functional
specification and on subsystem level.
The test cases defined based on the security functionality specified in the
functional specification showed the conformance to the expected behaviour of
the TOE in the personalization and operational phase. The tests were
performed using a smart card simulator and real chips with the TOE software
and the ICAO file-system.
The evaluator repeated developer tests by sampling. The sample covered all
security functions and was performed by using real chips and an emulator. The
TOE operated as specified.
Independent evaluator tests were performed in phase 5 (completion of the
smart card operating system), phase 6 (initialisation and personalization of the
MRTD) and in phase 7 (Operational phase of the MRTD) of the TOE. The tests
confirmed the expected behaviour as specified.
The evaluators penetration tests confirmed the effectiveness of all security
functions of the TOE. During these tests the different life cycle phases were
considered. The penetration tests were performed based on the developers
vulnerability analysis and based on the independent vulnerability analysis of the
evaluator. Potential vulnerabilities were assessed upon their exploitability by
analysis and tests. Analysis results and tests results showed that potential
vulnerabilities are not exploitable in the intended operational environment of the
TOE and that the TOE is resistant against low attack potential AVA_VLA.2 as
specified.
8 Evaluated Configuration
The TOE is delivered at the end of phase 6.1 in form of initialised and tested
inlay module. This corresponds to the end of life cycle phase 2 of the Protection
Profile MRTD BAC PP [8].
All procedures for personalisation and configuration for the end-user necessary
after delivery are described in the Administrator Guidance document [16].

9 Results of the Evaluation
The Evaluation Technical Report (ETR), [7] was provided by the ITSEF
according to the Common Criteria [1], the Methodology [2], the requirements of
the Scheme [3] and all interpretations and guidelines of the Scheme (AIS) [4] as
relevant for the TOE.
As the evaluation of the TOE was conducted as a composition evaluation, the
ETR [7] includes also the evaluation results of the composite evaluation activi-
ties in accordance with CC Supporting Document, ETR-lite for Composition:
Annex A Composite smart card evaluation [4, AIS 36]. The ETR [7] builds up on
the ETR-lite for Composition document of the evaluation of the underlying
Philips chip P5CT072V0N (see BSI-DSZ-CC-0312-2005 [12]) and the Infineon
chip SLE66CLX641P (BSI-DSZ-CC-0338-2005 [13]).
The evaluation methodology CEM [2] was used for those components identical
with EAL4. For components beyond EAL4 the methodology was defined in co-
ordination with the Certification Body [4, AIS 34]). For smart card specific
methodology the scheme interpretations AIS 25, AIS 26 and AIS 36 (see [4])
were used.

Table 6: Verdicts for the assurance components
The evaluation has shown that:
• the TOE is conformant to the PP Machine Readable Travel Document
with „ICAO Application", Basic Access Control, version 1.0 (BSI-PP-
0017-2005) [8]
• Security Functional Requirements specified for the TOE are PP
conformant and Common Criteria Part 2 extended
• the assurance of the TOE is Common Criteria Part 3 conformant, EAL4
augmented by ADV_IMP.2 (Implementation of the TSF) and ALC_DVS.2
(Sufficiency of security measures)
The following TOE Security Functions fulfil the claimed Strength of Function
SOF-high:
- Identification and Authentication based on Challenge-Response and
- Data exchange under secure messaging.
B-16
BSI-DSZ-CC-0316-2005 Certification Report
The rating of the strength of functions does not include the cryptoalgorithms
suitable for encryption and decryption (see BSIG Section 4, Para. 3, Clause 2).
This holds for the Triple-DES functionality.
For specific evaluation results regarding the development and production
environment see annex A in part D of this report.
The results of the evaluation are only applicable to the TCOS Passport Version
1.01 / P5CT072 and TCOS Passport Version 1.01 / SLE66CLX641P. The
validity can be extended to new versions and releases of the product, provided
the sponsor applies for re-certification or assurance continuity of the modified
product, in accordance with the procedural requirements, and the evaluation of
the modified product does not reveal any security deficiencies.
10 Comments/Recommendations
The operational documents [16] and [17] contain necessary information about
the usage of the TOE and all security hints therein have to be considered.
The TOEs implemented security functions meet the claimed strength of function
SOF-high from design and construction point of view. The strength of function
available in a specific system context where the TOE is used depends on the
selection of the data used to set up the communication to the TOE. Therefore
the issuing state or organisation is responsible for the strength of function that
can be achieved in a specific system context. This has to be assessed in the
specific system context. Then, the administrator (personalizer) is in
collaboration with the issuing state or organisation responsible to provide keys
with sufficient entropy, as required by the specific system context.
Only chips from the production sites (waferfabs, module and inlay production
sites) as outlined in the certification reports for the Philips chip P5CT072V0N
(BSI-DSZ-CC-0312-2005 [12]) and for the Infineon chip SLE66CLX641P (BSI-
DSZ-CC-0338-2005 [13]) shall be used.
The Personalization Agent has to verify that they got the correct version of the
TOE.
Defect chips and invalid passports including a chip must be destroyed in a way
that the chip itself is destructed..

CC Part 1:
Caveats on evaluation results (chapter 5.4) / Final Interpretation 008
The conformance result indicates the source of the collection of requirements
that is met by a TOE or PP that passes its evaluation. This conformance result
is presented with respect to Part 2 (functional requirements), Part 3 (assurance
requirements) and, if applicable, to a pre-defined set of requirements (e.g., EAL,
Protection Profile).
The conformance result consists of one of the following:
Part 2 conformant - A PP or TOE is Part 2 conformant if the functional
requirements are based only upon functional components in Part 2
Part 2 extended - A PP or TOE is Part 2 extended if the functional
requirements include functional components not in Part 2
plus one of the following:
Part 3 conformant - A PP or TOE is Part 3 conformant if the assurance
requirements are based only upon assurance components in Part 3
Part 3 extended - A PP or TOE is Part 3 extended if the assurance
requirements include assurance requirements not in Part 3.
Additionally, the conformance result may include a statement made with respect
to sets of defined requirements, in which case it consists of one of the following:
Package name Conformant - A PP or TOE is conformant to a pre-defined
named functional and/or assurance package (e.g. EAL) if the requirements
(functions or assurance) include all components in the packages listed as part
of the conformance result.
Package name Augmented - A PP or TOE is an augmentation of a pre-defined
named functional and/or assurance package (e.g. EAL) if the requirements
(functions or assurance) are a proper superset of all components in the
packages listed as part of the conformance result.
Finally, the conformance result may also include a statement made with respect
to Protection Profiles, in which case it includes the following:
PP Conformant - A TOE meets specific PP(s), which are listed as part of the
conformance result.

Evaluation assurance levels (chapter 6)
"The Evaluation Assurance Levels (EALs) provide an increasing scale that
balances the level of assurance obtained with the cost and feasibility of
acquiring that degree of assurance. The CC approach identifies the separate
concepts of assurance in a TOE at the end of the evaluation, and of
maintenance of that assurance during the operational use of the TOE.
It is important to note that not all families and components from Part 3 are
included in the EALs. This is not to say that these do not provide meaningful
and desirable assurances. Instead, it is expected that these families and
components will be considered for augmentation of an EAL in those PPs and
STs for which they provide utility."
Evaluation assurance level (EAL) overview (chapter 6.1)
Table 6.1 represents a summary of the EALs. The columns represent a
hierarchically ordered set of EALs, while the rows represent assurance families.
Each number in the resulting matrix identifies a specific assurance component
where applicable.
As outlined in the next section, seven hierarchically ordered evaluation
assurance levels are defined in the CC for the rating of a TOE's assurance.
They are hierarchically ordered inasmuch as each EAL represents more
assurance than all lower EALs. The increase in assurance from EAL to EAL is
accomplished by substitution of a hierarchically higher assurance component
from the same assurance family (i.e. increasing rigour, scope, and/or depth)
and from the addition of assurance components from other assurance families
(i.e. adding new requirements).
These EALs consist of an appropriate combination of assurance components as
described in chapter 2 of this Part 3. More precisely, each EAL includes no
more than one component of each assurance family and all assurance
dependencies of every component are addressed.
While the EALs are defined in the CC, it is possible to represent other
combinations of assurance. Specifically, the notion of “augmentation“ allows the
addition of assurance components (from assurance families not already
included in the EAL) or the substitution of assurance components (with another
hierarchically higher assurance component in the same assurance family) to an
EAL. Of the assurance constructs defined in the CC, only EALs may be
augmented. The notion of an “EAL minus a constituent assurance component“
is not recognised by the CC as a valid claim. Augmentation carries with it the
obligation on the part of the claimant to justify the utility and added value of the
added assurance component to the EAL. An EAL may also be extended with
explicitly stated assurance requirements.

Evaluation assurance level 1 (EAL1) - functionally tested (chapter 6.2.1)
"Objectives
EAL1 is applicable where some confidence in correct operation is required, but
the threats to security are not viewed as serious. It will be of value where
independent assurance is required to support the contention that due care has
been exercised with respect to the protection of personal or similar information.
EAL1 provides an evaluation of the TOE as made available to the customer,
including independent testing against a specification, and an examination of the
guidance documentation provided. It is intended that an EAL1 evaluation could
be successfully conducted without assistance from the developer of the TOE,
and for minimal outlay.
An evaluation at this level should provide evidence that the TOE functions in a
manner consistent with its documentation, and that it provides useful protection
against identified threats.“
Evaluation assurance level 2 (EAL2) - structurally tested (chapter 6.2.2)
"Objectives
EAL2 requires the co-operation of the developer in terms of the delivery of
design information and test results, but should not demand more effort on the
part of the developer than is consistent with good commercial practice. As such
it should not require a substantially increased investment of cost or time.
EAL2 is therefore applicable in those circumstances where developers or users
require a low to moderate level of independently assured security in the
absence of ready availability of the complete development record. Such a
situation may arise when securing legacy systems, or where access to the
developer may be limited.“
Evaluation assurance level 3 (EAL3) - methodically tested and checked
(chapter 6.2.3)
"Objectives
EAL3 permits a conscientious developer to gain maximum assurance from
positive security engineering at the design stage without substantial alteration of
existing sound development practices.
EAL3 is applicable in those circumstances where developers or users require a
moderate level of independently assured security, and require a thorough
investigation of the TOE and its development without substantial re-
engineering.“

Evaluation assurance level 4 (EAL4) - methodically designed, tested, and
reviewed (chapter 6.2.4)
"Objectives
EAL4 permits a developer to gain maximum assurance from positive security
engineering based on good commercial development practices which, though
rigorous, do not require substantial specialist knowledge, skills, and other
resources. EAL4 is the highest level at which it is likely to be economically
feasible to retrofit to an existing product line.
EAL4 is therefore applicable in those circumstances where developers or users
require a moderate to high level of independently assured security in
conventional commodity TOEs and are prepared to incur additional security-
specific engineering costs.“
Evaluation assurance level 5 (EAL5) - semiformally designed and tested
(chapter 6.2.5)
"Objectives
EAL5 permits a developer to gain maximum assurance from security
engineering based upon rigorous commercial development practices supported
by moderate application of specialist security engineering techniques. Such a
TOE will probably be designed and developed with the intent of achieving EAL5
assurance. It is likely that the additional costs attributable to the EAL5
requirements, relative to rigorous development without the application of
specialised techniques, will not be large.
EAL5 is therefore applicable in those circumstances where developers or users
require a high level of independently assured security in a planned development
and require a rigorous development approach without incurring unreasonable
costs attributable to specialist security engineering techniques.“
Evaluation assurance level 6 (EAL6) - semiformally verified design and
tested (chapter 6.2.6)
"Objectives
EAL6 permits developers to gain high assurance from application of security
engineering techniques to a rigorous development environment in order to
produce a premium TOE for protecting high value assets against significant
risks.
EAL6 is therefore applicable to the development of security TOEs for
application in high risk situations where the value of the protected assets
justifies the additional costs.“

Evaluation assurance level 7 (EAL7) - formally verified design and tested
(chapter 6.2.7)
"Objectives
EAL7 is applicable to the development of security TOEs for application in
extremely high risk situations and/or where the high value of the assets justifies
the higher costs. Practical application of EAL7 is currently limited to TOEs with
tightly focused security functionality that is amenable to extensive formal
analysis.“

Strength of TOE security functions (AVA_SOF) (chapter 14.3)
AVA_SOF Strength of TOE security functions
"Objectives
Even if a TOE security function cannot be bypassed, deactivated, or corrupted,
it may still be possible to defeat it because there is a vulnerability in the concept
of its underlying security mechanisms. For those functions a qualification of their
security behaviour can be made using the results of a quantitative or statistical
analysis of the security behaviour of these mechanisms and the effort required
to overcome them. The qualification is made in the form of a strength of TOE
security function claim.“
Vulnerability analysis (AVA_VLA) (chapter 14.4)
AVA_VLA Vulnerability analysis
"Objectives
Vulnerability analysis is an assessment to determine whether vulnerabilities
identified, during the evaluation of the construction and anticipated operation of
the TOE or by other methods (e.g. by flaw hypotheses), could allow users to
violate the TSP.
Vulnerability analysis deals with the threats that a user will be able to discover
flaws that will allow unauthorised access to resources (e.g. data), allow the
ability to interfere with or alter the TSF, or interfere with the authorised
capabilities of other users.“
"Application notes
A vulnerability analysis is performed by the developer in order to ascertain the
presence of security vulnerabilities, and should consider at least the contents of
all the TOE deliverables including the ST for the targeted evaluation assurance
level. The developer is required to document the disposition of identified
vulnerabilities to allow the evaluator to make use of that information if it is found
useful as a support for the evaluator's independent vulnerability analysis.“
"Independent vulnerability analysis goes beyond the vulnerabilities identified by
the developer. The main intent of the evaluator analysis is to determine that the
TOE is resistant to penetration attacks performed by an attacker possessing a
low (for AVA_VLA.2), moderate (for AVA_VLA.3) or high (for AVA_VLA.4)
attack potential.“
