2 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.
2.1 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 technical
domains only.
The basic recognition level includes Common Criteria (CC) Evaluation Assurance Levels
EAL1 to EAL4 and ITSEC Evaluation Assurance Levels E1 to E3 (basic). For higher
recognition levels the technical domain Smart card and similar Devices has been defined.
It includes assurance levels beyond EAL4 resp.E3 (basic).
The new agreement was initially signed by the national bodies of Finland, France,
Germany, The Netherlands, Norway, Spain, Sweden and the United Kingdom.

Certification Report BSI-DSZ-CC-0721-2012
Within the terms of this agreement the German Federal Office for Information Security
(BSI) recognises
● for the basic recognition level certificates issued as of April 2010 by the national
certification bodies of France, The Netherlands, Spain and United Kingdom.
● for the higher recognition level in the technical domain Smart card and similar Devices
certificates issued as of April 2010 by the national certification bodies of France, The
Netherlands and United Kingdom.
In Addition, certificates issued for Protection Profiles based on Common Criteria are part of
the recognition agreement.
The SOGIS-MRA logo printed on the certificate indicates that it is recognised under the
terms of this agreement.
Historically, the first SOGIS-Mutual Recognition Agreement Version 1 (ITSEC only)
became initially effective in March 1998. It was extended in 1999 to include certificates
based on the Common Criteria (MRA Version 2). Recognition of certificates previously
issued under these older versions of the SOGIS-Mutual Recognition Agreement is being
continued.
2.2 International Recognition of CC - Certificates
An arrangement (Common Criteria Recognition Arrangement) on the mutual recognition of
certificates based on the CC Evaluation Assurance Levels up to and including EAL 4 has
been signed in May 2000 (CCRA). It includes also the recognition of Protection Profiles
based on the CC.
As of January 2009 the arrangement has been signed by the national bodies of: Australia,
Austria, Canada, Czech Republic, Denmark, Finland, France, Germany, Greece, Hungary,
India, Israel, Italy, Japan, Republic of Korea, Malaysia, The Netherlands, New Zealand,
Norway, Pakistan, Republic of Singapore, Spain, Sweden, Turkey, United Kingdom, United
States of America. The current list of signatory nations and approved certification schemes
can be seen on the web site: http://www.commoncriteriaportal.org
The Common Criteria Recognition Arrangement logo printed on the certificate indicates
that this certification is recognised under the terms of this agreement.
3 Performance of Evaluation and Certification
The certification body monitors each individual evaluation to ensure a uniform procedure, a
uniform interpretation of the criteria and uniform ratings.
The product SAP NetWeaver Application Server ABAP 7.02 SP8 (Unicode Kernel 64 bit)

BSI-DSZ-CC-0721-2012 Certification Report
The product was developed by: SAP AG.
The certification is concluded with the comparability check and the production of this
Certification Report. This work was completed by the BSI.
4 Validity of the Certification Result
This Certification Report only applies to the version of the product as indicated. The
confirmed assurance package is only valid on the condition that
● all stipulations regarding generation, configuration and operation, as given in the
following report, are observed,
● the product is operated in the environment described, where specified in the following
report and in the Security Target.
For the meaning of the assurance levels please refer to the excerpts from the criteria at
the end of the Certification Report.
The Certificate issued confirms the assurance of the product claimed in the Security Target
at the date of certification. As attack methods evolve over time, the resistance of the
certified version of the product against new attack methods needs to be re-assessed.
Therefore, the sponsor should apply for the certified product being monitored within the
assurance continuity program of the BSI Certification Scheme (e.g. by a re-certification).
Specifically, if results of the certification are used in subsequent evaluation and certification
procedures, in a system integration process or if a user's risk management needs regularly
updated results, it is recommended to perform a re-assessment on a regular e.g. annual
basis.
In case of changes to the certified version of the product, the validity can be extended to
the new versions and releases, provided the sponsor applies for assurance continuity (i.e.
re-certification or maintenance) of the modified product, in accordance with the procedural
requirements, and the evaluation does not reveal any security deficiencies.

1 Executive Summary
The Target of Evaluation (TOE) defined as SAP NetWeaver Application Server ABAP 7.02
SP8 (Unicode Kernel 64 bit) with Common Criteria Addendum (Material No. 51041562) (in
the following referred to as SAP NetWeaver Application Server ABAP 7.02 SP8) consists
solely of software (accompanied by the associated guidance documentation). This
software application represents a fundamental component used in modern SAP systems.
As an application server, the TOE represents a framework for the development and
execution of business applications based on the ABAP programming language. The TOE
provides a complex set of services and infrastructure to be used by such applications.
The Security Target [6] is the basis for this certification. It is not based on a certified
Protection Profile.
The TOE Security Assurance Requirements (SAR) are based entirely on the assurance
components defined in Part 3 of the Common Criteria (see part C or [1], Part 3 for details).
The TOE meets the assurance requirements of the Evaluation Assurance Level EAL 4
augmented by ALC_FLR.1.
The TOE Security Functional Requirements (SFR) relevant for the TOE are outlined in the
Security Target [6] chapter 6.2. They are all selected from Common Criteria Part 2. Thus
the TOE is CC Part 2 conformant.
The TOE Security Functional Requirements are implemented by the following TOE
Security Functionality:
TOE Security Functionality Addressed issue
Audit The TOE maintains a security log to keep track of security
relevant events and provides functionality for review of the audit
to authorized administrators.
Users and Authorization The TOE provides an access control functionality in order to
ensure that only authorized administrators can use the
management functionality of the TOE, as well as functionality
for authorization checks to applications that are hosted by the
TOE.
Identification and Authentication In order to allow access control the TOE has to be aware of the
identity of the connected user. Therefore the TOE provides an
identification and authentication function based on usernames
and passwords.
Security Management The TOE provides the management functionality necessary for
the administration of the security functionality.
Table 1: TOE Security Functionality
For more details please refer to the Security Target [6], chapter 7.
The assets to be protected by the TOE are defined in the Security Target [6], chapter 3.2.
Based on these assets the TOE Security Problem is defined in terms of Assumptions,
Threats and Organisational Security Policies. This is outlined in the Security Target [6],
chapters 3.3, 3.4 and 3.5.
For the configurations of the TOE covered by this certification please refer to chapter 8 of
this report.

Table 2: Deliverables of the TOE
The TOE (software accompanied by guidance documentation, see items No. 1, 2 and 5 of
Table 2 above) is delivered partly via physical distribution on a set of DVDs (comprising 5
DVDs) and partly (particularly Guidance addendum) via download from a dedicated
website [12]. Additional components (like the integrity check tool, files and data) are part of
the delivery process as they are required for the TOE integrity check process.
The TOE label is displayed to the consumer in various forms during the delivery,
installation and operational phase of the TOE. In detail, the TOE can be identified by the
following methods referring to the placement of label as well as the kind of label (e.g.
electronically, engraved, printed, etc.):
● Service Marketplace (SAP internet portal for software delivery) [15]: TOE referenced
by its reference label SAP NetWeaver Application Server ABAP 7.02 SP8 (Unicode
Kernel 64 bit) with Common Criteria Addendum (Material No. 51041562).
● Delivery media (DVD set with the TOE installation media): TOE referenced as SAP
EHP2 FOR SAP NETWEAVER 7.0. The DVD set shipped physically is equipped
with a label, i.e. the DVDs include the identifier „SAP EHP2 FOR SAP
NETWEAVER 7.0 , and the Common Criteria Addendum DVD additionally includes
‟
the information „SPS03 – SPS08 Common Criteria Addendum". It should be noted
that the reference „SAP EHP2 FOR SAP NETWEAVER 7.0 is equivalent to the
‟
identification „SAP NetWeaver Application Server ABAP 7.02", since the information
„EHP2 for 7.0 corresponds one-to-one to the product release „7.02 . After
‟ ‟
installation of the installation basis DVDs and the Common Criteria Addendum DVD
(Material No. 51041562) the complete TOE SAP NetWeaver Application Server
ABAP 7.02 SP8 (Unicode Kernel 64 bit) with Common Criteria Addendum (Material
No. 51041562) is build. This DVD labeling facilitates the TOE identification for
consumers at the point of receipt of the DVDs.
● TOE installation process: The installation software displays the TOE version in
various situations.
● Operational TOE: In the running TOE, several status info screens are available via
the SAPGUI interface or command line interface containing the version info of the
underlying TOE. For further information please refer to chapter 3.4 of the Guidance
addendum [9]. Together, the ABAP software components and the kernel component
14 / 40
BSI-DSZ-CC-0721-2012 Certification Report
make up the TOE, i.e. SAP NetWeaver Application Server ABAP 7.02 SP8 (Unicode
Kernel 64 bit) with Common Criteria Addendum (Material No. 51041562).
Both parts of the guidance documentation (consisting of TOE documentation [10] and
Guidance addendum [9]) include a unique reference, so that it is possible to identify them
uniquely. In addition, table 2 contains the SHA-1 checksum for the Guidance Addendum in
order to enable customers to verify the correctness of the guidance document obtained.
3 Security Policy
The Security Policy is expressed by the set of Security Functional Requirements and
implemented by the TOE. It covers the following issues:
● Audit
● Users and Authorization
● Identification and Authentication
● Security Management
For more information on these issues, see Security Target [6], chapter 1.3.4.
4 Assumptions and Clarification of Scope
The Assumptions defined in the Security Target and some aspects of Threats and
organisational Security Policies are not covered by the TOE itself. These aspects lead to
specific security objectives to be fulfilled by the TOE-Environment. The following topics are
of relevance:
● It is assumed that one or more competent and well trained administrators are
assigned to manage the TOE and the security of the information it contains. The
administrators are neither careless, wilfully negligent, nor hostile.
● The administrators know and follow all instructions provided in the relevant
guidance documentation.
● Further, it is assumed that the emergency user account SAP* is disabled in the
operational use of the TOE.
● Administrators and users must ensure that the authentication data for each user
account for the TOE is held securely and is not disclosed to persons not authorized
to use that account.
● The TOE is connected to the intranet and/or terminals and workstations.
● It is assumed that the development of applications (for the NetWeaver Application
Server ABAP) will comply with all the guidelines and restrictions specified in the
SAP Programmer’s Guidance.
● It is assumed that the necessary IT infrastructure for the TOE is available.
● The TOE and its underlying abstract machine are located within controlled access
facilities that will prevent unauthorized physical access.
● It is assumed that the TOE is used with suitable user interfaces as set out in the
TOE guidance documents, for example SAP GUI or web based.
Details can be found in the Security Target [6], chapter 3.3.

consideration of the subsystems:
The TOE consists of the following subsystems:
Subsystem Description
Dispatcher/ICM ● Handles all network requests to the TOE.
● Passes requests to the ABAP Kernel which does the actual
processing.
ABAP Kernel ● The ABAP Kernel implements the work process concept.
● Receives requests from the Dispatcher.
● Transports data to/from the underlying database.
● Implements the authentication and authorization checks.
● Implements access to the log files and to the log
configuration.
ABAP Logon and Session Management ● Handles logon to the TOE and declarative access checks of
transactions.
● Limits access to TSF management applications to authorized
administrators.
● Triggers a subset of the log events.
Internet Communication Framework
(ICF)
● Can be used to receive HTTP requests.
● Exposes ICF services on the TOE.
ABAP User, Group and Role
Maintenance
● Allows to manage users, groups and roles in the TOE
including the definition of security attributes which are
restrictive by default.
ABAP Security Audit Log Configuration
and Analysis
● Produces a log containing security-related system events
such as configuration changes or unsuccessful logon
attempts.

6 Documentation
The evaluated documentation as outlined in table 2 (No. 2 and 5) is being provided with
the product to the customer. This documentation contains the required information for
secure usage of the TOE in accordance with the Security Target.
Additional obligations and notes for secure usage of the TOE as outlined in chapter 10 of
this report have to be followed.
7 IT Product Testing
7.1 Developer Testing
TOE Test Configuration
All developer's tests in the context of the evaluation have been conducted using the final
version of the TOE. Independently on whether manual or automatic tests were performed
the following software configuration was in place:
● Operating System: Microsoft Windows Server 2008, Enterprise Edition (64 Bit)
● Additional Software: JDK Version “1.4.2”
The developer used the following hardware for automated and manual testing as stated
below:
● Intel Core i5 M520 2.4GHZ CPU based PC with 8 GB RAM and 298 GB hard disk
space.
Testing Approach
The developer used three different test tools for different aspects of the testing activities.
The following table gives an overview about the used tools:
Tool Purpose / Field of application
GTP (Global Test Production) Tool to manage manual test cases.
ECATT (Extended Computer Aided Test Tool) Tool to execute automated test cases based on ECATT.
VERI (VERIfication Workbench) Tool to execute automated test cases based on VERI.
Table 4: Used test tools
The developer followed the strategy to cover each relevant part with at least one
appropriate test case testing the corresponding security functionality.
A test case thereby consists of several test steps which are executed sequentially and
which results are compared to the expected results. Only if all checks of all test steps are
successful, the corresponding test case passes.
The developer has tested the TOE systematically at the level of TSFI as well as at the
level of subsystems.
Conclusion
The developer's testing effort has been proven sufficient to demonstrate that the TOE
security functions perform as specified and did pass the evaluator's examination. The tests
results demonstrate that no discrepancy between the TOE behaviour and the TOE
specification has been found.

Certification Report BSI-DSZ-CC-0721-2012
7.2 Evaluator Independent Testing
TOE Test Configuration
The TOE was tested in the following configurations:
1. Repetition of developer tests:
• SAP EHP 2 for SAP NetWeaver 7.0 SP8 is installed on Microsoft Windows
Server 2008 Enterprise. The TOE uses a MaxDB database 7.8.01.014 which is
installed on the same machine.
• The hardware used for the repetition of the developer tests is an Intel Core i5
M520 2.4GHZ CPU based PC with 8 GB RAM and 298 GB hard disk space.
2. Evaluation body's own testing:
SAP NWAS ABAP 7.02 SP8 installed according to [9] on:
• Hardware: Intel Xeon CPU, 8GB RAM, Dual Core, 2 GHz
• Software: Microsoft Windows Server 2008 Enterprise Edition (64 bit)
Testing Approach
The evaluator repeated all automatic developer tests in order to verify the adequateness of
the automated test tools used by the developer. In total, 291 automated developer test
cases were repeated.
The evaluator further developed a set of own manual test cases for functional testing.
Thereby he had chosen the approach to cover TSF from all the functional areas of the
TOE (Audit, I&A, Users and Authorization, and Security Management). This approach
extends the one used for the developer tests were all TSFI have been tested, so that both
TSF and TSFI coverage is given. The evaluator devised and performed 6 functional tests,
12 penetration tests, and 5 other tests.
Tested Interfaces
The following TSFI where used for testing of SFR-relevant behavior during evaluation
body testing:
● DIAG
● HTTP(S)
● ABAP User Management
● ABAP Group Management
● ABAP Role Management
● ABAP Security Audit Log Deletion
● ABAP Security Audit Log Configuration
● ABAP Security Audit Log Analysis
● ABAP Profile Parameter Modification
● ABAP ICF Administration
● ABAP Session Manager
● SAPGUI Logon Page
18 / 40
BSI-DSZ-CC-0721-2012 Certification Report
● ABAP HTTP Server
● ABAP Wrappers
● ABAP Statements
● ABAP Kernel Calls
● ABAP System Modules
Conclusion
The overall judgement on the results of independent testing consisting of:
● Developer test repetition (sampling)
● TSF subset and TSFI testing
● Other Testing
is that the TOE security functionality and TSFI are successfully tested and actually have
the effects as specified.
7.3 Evaluator Penetration Testing
TOE Test Configuration
The TOE configuration used for testing is identified in the following:
● TOE:
• SAP NetWeaver Application Server ABAP 7.02 SP8 (Unicode Kernel 64 bit) with
Common Criteria Addendum (Material No. 51041562)
● Platform:
• Operating system „Microsoft Windows Server Enterprise Edition (64 bit), version
6.0.6001‟
• Java runtime environment (JRE), version 1.4.2
● Hardware:
• Intel Xeon CPU E5504 @ 2.00GHz (64 bit), 8 GB RAM
Testing Approach
The evaluator analyzed the development and guidance documentation from an attacker's
perspective to find security flaws in design and implementation of the TOE. In addition to
that he applied security scanners to find common vulnerabilities in web applications and
used a static code analysis tool to detect programming errors in TOE functionality that
could lead to security vulnerabilities.
Conclusion
The overall test result is that no deviations were found between the expected and the
actual test results. No attack scenario with the attack potential Enhanced-basic was
actually successful in the TOE's operational environment as defined in [6] provided that all
measures required by the developer are applied.
8 Evaluated Configuration
This certification covers the following configurations of the TOE:
19 / 40
Certification Report BSI-DSZ-CC-0721-2012
The TOE under evaluation is SAP NetWeaver Application Server ABAP 7.02 SP8 (Unicode
Kernel 64 bit) with Common Criteria Addendum (Material No. 51041562). The Security
Target [6] has identified solely one configuration (NWAS ABAP single stack mode
installation) of the TOE under evaluation. This configuration is achieved by strict
adherence to the Guidance addendum [9]. The TOE as specified in the Security Target [6]
is set up as a single system, i.e. its environment does not connect to other SAP systems or
application servers.
The operational environment of the TOE in its evaluated configuration can be summarized
as follows:
● Software requirements:
• TOE platform (OS): Microsoft Windows Server 2008 Enterprise Edition,
• Java runtime environment (JRE), version 1.4.2;
● Hardware requirements (minimum characteristics):
• CPU: 1.4 GHz (x64 processor)
• RAM: 5 GB
• Hard Disk: 64 GB,
• Others: VGA (800 × 600) or higher resolution monitor, DVD Drive, Keyboard and
Mouse (or compatible pointing device)
9 Results of the Evaluation
9.1 CC specific results
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 a result of the evaluation the verdict PASS is confirmed for the following assurance
components:
● All components of the EAL 4 package including the class ASE as defined in the CC (see
also part C of this report)
● The components ALC_FLR.1 augmented for this TOE evaluation.
The evaluation has confirmed:
● PP Conformance: None
● for the Functionality: Product specific Security Target
Common Criteria Part 2 conformant
● for the Assurance: Common Criteria Part 3 conformant
EAL 4 augmented by ALC_FLR.1
The results of the evaluation are only applicable to the TOE as defined in chapter 2 and
the configuration as outlined in chapter 8 above.

9.2 Results of cryptographic assessment
The TOE does not include cryptographic algorithms. Thus, no such mechanisms were part
of the assessment.
10 Obligations and Notes for the Usage of the TOE
The documents as outlined in table 2 contain necessary information about the usage of the
TOE and all security hints therein have to be considered. 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.
If available, certified updates of the TOE should be used. If non-certified updates or
patches are available the user of the TOE should request the sponsor to provide a re-
certification. In the meantime a risk management process of the system using the TOE
should investigate and decide on the usage of not yet certified updates and patches or
take additional measures in order to maintain system security.
In addition, the following aspects need to be fulfilled when using the TOE:
● Prior to installation and usage of the TOE the integrity of the downloaded Guidance
Addendum [9] should be checked by means of its hash value calculation and be
compared with the hash value listed in section 2 above (see Table 2, No. 4).
There are no other requirements for the TOE usage, except those provided for TOE
users/administrators in the guidance documentation consisting of the TOE documentation
[10] and Guidance Addendum [9]. In particular, the recommendations and requirements for
secure administration, configuration and usage of the TOE have to be followed to operate
the TOE in its evaluated configuration.

C Excerpts from the Criteria
CC Part1:
Conformance Claim (chapter 10.4)
“The conformance claim indicates the source of the collection of requirements that is met
by a PP or ST that passes its evaluation. This conformance claim contains a CC
conformance claim that:
● describes the version of the CC to which the PP or ST claims conformance.
● describes the conformance to CC Part 2 (security functional requirements) as either:
– CC Part 2 conformant - A PP or ST is CC Part 2 conformant if all SFRs in that
PP or ST are based only upon functional components in CC Part 2, or
– CC Part 2 extended - A PP or ST is CC Part 2 extended if at least one SFR in
that PP or ST is not based upon functional components in CC Part 2.
● describes the conformance to CC Part 3 (security assurance requirements) as either:
– CC Part 3 conformant - A PP or ST is CC Part 3 conformant if all SARs in that
PP or ST are based only upon assurance components in CC Part 3, or
– CC Part 3 extended - A PP or ST is CC Part 3 extended if at least one SAR in
that PP or ST is not based upon assurance components in CC Part 3.
Additionally, the conformance claim may include a statement made with respect to
packages, in which case it consists of one of the following:
● Package name Conformant - A PP or ST is conformant to a pre-defined package
(e.g. EAL) if:
– the SFRs of that PP or ST are identical to the SFRs in the package, or
– the SARs of that PP or ST are identical to the SARs in the package.
● Package name Augmented - A PP or ST is an augmentation of a predefined package
if:
– the SFRs of that PP or ST contain all SFRs in the package, but have at least
one additional SFR or one SFR that is hierarchically higher than an SFR in the
package.
– the SARs of that PP or ST contain all SARs in the package, but have at least
one additional SAR or one SAR that is hierarchically higher than an SAR in the
package.
Note that when a TOE is successfully evaluated to a given ST, any conformance claims of
the ST also hold for the TOE. A TOE can therefore also be e.g. CC Part 2 conformant.
Finally, the conformance claim may also include two statements with respect to Protection
Profiles:
● PP Conformant - A PP or TOE meets specific PP(s), which are listed as part of the
conformance result.
● Conformance Statement (Only for PPs) - This statement describes the manner in
which PPs or STs must conform to this PP: strict or demonstrable. For more
information on this Conformance Statement, see Annex D.”

Evaluation assurance levels (chapter 8)
“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 CC 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 8.1)
“Table 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 7 of this CC 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 standard 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 augmented with extended
assurance requirements.

32 / 40
BSI-DSZ-CC-0721-2012 Certification Report
Evaluation assurance level 1 (EAL1) - functionally tested (chapter 8.3)
“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 requires only a limited security target. It is sufficient to simply state the SFRs that the
TOE must meet, rather than deriving them from threats, OSPs and assumptions through
security objectives.
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.”
Evaluation assurance level 2 (EAL2) - structurally tested (chapter 8.4)
“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 practise. 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 8.5)
“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 practises.
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.”
33 / 40
Certification Report BSI-DSZ-CC-0721-2012
Evaluation assurance level 4 (EAL4) - methodically designed, tested, and reviewed
(chapter 8.6)
“Objectives
EAL4 permits a developer to gain maximum assurance from positive security engineering
based on good commercial development practises 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 8.7)
“Objectives
EAL5 permits a developer to gain maximum assurance from security engineering based
upon rigorous commercial development practises 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 8.8)
“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.”
34 / 40
BSI-DSZ-CC-0721-2012 Certification Report
Evaluation assurance level 7 (EAL7) - formally verified design and tested
(chapter 8.9)
“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.”
Class AVA: Vulnerability assessment (chapter 16)
“The AVA: Vulnerability assessment class addresses the possibility of exploitable
vulnerabilities introduced in the development or the operation of the TOE.”
Vulnerability analysis (AVA_VAN) (chapter 16.1)
"Objectives
Vulnerability analysis is an assessment to determine whether potential vulnerabilities
identified, during the evaluation of the development and anticipated operation of the TOE
or by other methods (e.g. by flaw hypotheses or quantitative or statistical analysis of the
security behaviour of the underlying security mechanisms), could allow attackers to violate
the SFRs.
Vulnerability analysis deals with the threats that an attacker will be able to discover flaws
that will allow unauthorised access to data and functionality, allow the ability to interfere
with or alter the TSF, or interfere with the authorised capabilities of other users.”
