A. Certification
1. Preliminary Remarks
Under the BSIG1
Act, the Federal Office for Information Security (BSI) has the task of
issuing certificates for information technology products.
Certification of a product is carried out on the instigation of the vendor or a distributor,
hereinafter called the sponsor.
A part of the procedure is the technical examination (evaluation) of the product according
to the security criteria published by the BSI or generally recognised security criteria.
The evaluation is normally carried out by an evaluation facility recognised by the BSI or by
BSI itself.
The result of the certification procedure is the present Certification Report. This report
contains among others the certificate (summarised assessment) and the detailed
Certification Results.
The Certification Results contain the technical description of the security functionality of
the certified product, the details of the evaluation (strength and weaknesses) and
instructions for the user.
2. Specifications of the Certification Procedure
The certification body conducts the procedure according to the criteria laid down in the
following:
● Act on the Federal Office for Information Security1
● BSI Certification and Approval Ordinance2
● BSI Schedule of Costs, BMI Regulations on Ex-parte Costs 3
● Special decrees issued by the Bundesministerium des Innern (Federal Ministry of the
Interior)
● DIN EN ISO/IEC 17065 standard
● BSI certification: Scheme documentation describing the certification process (CC-
Produkte) [3]
● BSI certification: Scheme documentation on requirements for the Evaluation Facility, its
approval and licencing process (CC-Stellen) [3]

3. 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.
3.1. European Recognition of 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. 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 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 related bodies of the signatory nations. A disclaimer
beneath the logo indicates the specific scope of recognition.
This certificate is recognized according to the rules of SOGIS-MRA, i.e. up to and including
CC part 3 EAL 4 components. The evaluation contained the components ALC_FLR.2,
ASE_TSS.2 and AVA_VAN.4 that are not mutually recognised in accordance with the
provisions of the SOGIS MRA. For mutual recognition the EAL 4 components of these
assurance families are relevant.
3.2. 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 current list of signatory nations and approved certification schemes can be seen on
the website: https://www.commoncriteriaportal.org.

Certification Report BSI-DSZ-CC-1142-2020
The Common Criteria Recognition Arrangement logo printed on the certificate indicates
that this certification is recognised under the terms of this agreement by the related bodies
of the signatory nations. A disclaimer beneath the logo indicates the specific scope of
recognition.
This certificate is recognized according to the rules of CCRA-2014, i. e. up to and including
CC part 3 EAL 2+ ALC_FLR components.
4. 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 genuscreen 7.0 has undergone the certification procedure at BSI. This is a re-
certification based on BSI-DSZ-CC-1085-2019. Specific results from the evaluation
process BSI-DSZ-CC-1085-2019 were re-used.
The evaluation of the product genuscreen 7.0 was conducted by secuvera GmbH. The
evaluation was completed on 7 August 2020. secuvera GmbH is an evaluation facility
(ITSEF)5
recognised by the certification body of BSI.
For this certification procedure the sponsor and applicant is: genua GmbH.
The product was developed by: genua GmbH.
The certification is concluded with the comparability check and the production of this
Certification Report. This work was completed by the BSI.
5. Validity of the Certification Result
This Certification Report applies only to the version of the product as indicated. The
confirmed assurance package is 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, as specified in the following report
and in the Security Target.
For the meaning of the assurance components and assurance levels please refer to CC
itself. Detailed references are listed in part C of this 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-assessment or
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 order to avoid an indefinite usage of the certificate when evolved attack methods would
require a re-assessment of the products resistance to state of the art attack methods, the

BSI-DSZ-CC-1142-2020 Certification Report
maximum validity of the certificate has been limited. The certificate issued on 18 August
2020 is valid until 17 August 2025. Validity can be re-newed by re-certification.
The owner of the certificate is obliged:
1. when advertising the certificate or the fact of the product's certification, to refer to
the Certification Report as well as to provide the Certification Report, the Security
Target and user guidance documentation mentioned herein to any customer of the
product for the application and usage of the certified product,
2. to inform the Certification Body at BSI immediately about vulnerabilities of the
product that have been identified by the developer or any third party after issuance
of the certificate,
3. to inform the Certification Body at BSI immediately in the case that security relevant
changes in the evaluated life cycle, e.g. related to development and production sites
or processes, occur, or the confidentiality of documentation and information related
to the Target of Evaluation (TOE) or resulting from the evaluation and certification
procedure where the certification of the product has assumed this confidentiality
being maintained, is not given any longer. In particular, prior to the dissemination of
confidential documentation and information related to the TOE or resulting from the
evaluation and certification procedure that do not belong to the deliverables
according to the Certification Report part B, or for those where no dissemination
rules have been agreed on, to third parties, the Certification Body at BSI has to be
informed.
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.
6. Publication
The product genuscreen 7.0 has been included in the BSI list of certified products, which is
published regularly (see also Internet: https://www.bsi.bund.de and [5]). Further
information can be obtained from BSI-Infoline +49 228 9582-111.

1. Executive Summary
The TOE genuscreen 7.0 is a distributed stateful packet filter firewall system with VPN
capabilities and central configuration. It provides basic IPv6 support and protects networks
at the border to the Internet by filtering incoming and outgoing data traffic. It protects data
flow between several protected networks against unauthorised inspection and
modification. It consists of software on a number of machines (genuscreen appliances)
that work as network filters, hereafter called firewall components, and the management
system (genucenter management system), a central component to manage this network of
firewall components.
The firewall components are initialised on a secure network from the management system.
The TOE provides IPv4 and basic IPv6 support. After initialisation, the firewall components
can be distributed to the locations of the networks they are protecting.
The genuscreen firewall components filter incoming and outgoing traffic for multiple
networks and can thus enforce a given security policy on the data flow. The filter is
implemented in the kernel of the firewall components’ operating system, OpenBSD. The
firewall components can work as bridges or routers. The firewall components can be used
in an optional high availability (HA) setup where the firewall components synchronize their
internal states.
The firewall components can provide confidentiality and integrity for data traffic passing
between the networks. This Virtual Private Network function is achieved by IPsec
encryption and authentication mechanisms.
The TOE includes an optional SIP relay to allow the usage of a Session Border Controller
(SBC). The SIP relay is not included in the basic installation image but must be installed as
an optional module at the genucenter. The SIP relay software is then installed on all
appliances that use the relay.
The management system component provides administrators with a Graphical User
Interface (GUI) to initialise and manage the firewall components from a central server. The
management system also allows collecting audit data and monitoring. The communication
server between the genuscreen appliances and the genucenter management system
avoids exposing the genucenter to the Internet. The connection between the genucenter
and genuscreens is encrypted with SSH.
The TOE contains cryptographic functionality. The cryptographic algorithms are part of the
TOE. This includes the random number generator which is of class DRG.3 (see AIS20 [4]).
The physical scope of TOE consists only of software and documentation. The TOE does
not include any hardware or firmware. The genucenter must be operated on real hardware.
Running the genucenter in a virtual machine is out of scope for this TOE.
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.2, ASE_TSS.2 and AVA_VAN.4.
The TOE Security Functional Requirements (SFR) relevant for the TOE are outlined in the
Security Target [6], chapter 6. They are selected from Common Criteria Part 2 and some of
them are newly defined. Thus the TOE is CC Part 2 extended.

3. Security Policy
The Security Policy is expressed by the set of Security Functional Requirements and
implemented by the TOE. The following security policies are defined for the TOE.
These policies are defined by the ST [6]:
● Firewall SFP: creation, modification, deletion and application of firewall security policy
rules.
● Network Separation SFP: network separation using routing domains.
● IPSEC: flow control functions in relation to the VPN connections between the firewall
components.
● IKE-SFP: cryptographic functions in relation to the key management of the VPN
connections between the firewall components.
● SSH-SFP: flow control functions in relation to the communication between the
management system and the firewall components.
● SIP Relay: access control by the SIP relay.
● Administration: administration of the TOE.
● Identification and Authentication: identification and authentication of administrators,
service users and revisors.
● Audit: audit capabilities of the TOE.
● General Management Facilities: general management of the TOE.
● Random Number Generation: generation of random numbers.
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 topics as depicted
in the ST [6], chapter 4.2 are of relevance.
5. Architectural Information
The TOE is the firewall system genuscreen 7.0 developed by genua GmbH.
The TOE consists of
● several firewall components that work as network filters and encrypting gateways,
● a central Management Server that is used to configure, administrate and monitor the
firewall components.
The Management Server allows authorised administrators to configure filter rules and
protection policies on the firewall components by use of a web-based graphical user
interface (GUI) at the Management Server. It also enables authorised administrators to
update the software on the firewall components. The GUI must only be used from a trusted
machine connected to the management Server through a trusted network.
16 / 27
BSI-DSZ-CC-1142-2020 Certification Report
After installation, all communication between the Management Server and the firewall
components is protected by Secure Shell (SSH) transforms against eavesdropping and
modification.
The firewall components employ IPsec based encryption and authentication to protect data
flows between the subnets assigned to them by the authorised administrators.
The firewall components can be used in an optional high availability (HA) setup where the
firewall components synchronize their internal states. In case of one system breaks down
the function of this component is resumed by the other.
Management consists of definition/modification and transmission of firewall policies and
security policies for network traffic. The GUI also allows transfer of audit data from the
firewall components.
The TOE provides VPN and firewall functionality and is easy to manage. It protects
networks at the border of the Internet by filtering data. It also protects data flowing
between several protected networks against unauthorised inspection and modification. It
consists of software on at least two machines (genuscreen appliances) that filter incoming
and outgoing traffic for multiple networks. The firewall components (genuscreen
appliances) provide confidentiality and integrity for data traffic passing between the
networks by using IPsec encryption/authentication functionality. The firewall components
can work as bridges and routers. Cryptographic operations are part of the TOE. The TOE
provides IPv4 and basic IPv6 support.
The TOE includes an optional SIP relay. The SIP relay is not included in the basic
installation image but must be installed as an optional module at the genucenter. The SIP
relay software is then installed on all appliances that use the relay.
The TOE also includes a central component, the Management Server, to manage the
firewall components (genucenter). Administrators can initialise and manage the firewall
components using a graphical user interface (GUI) for the Management Server. The GUI
of the management server supports three types of user roles, i.e. Administrator, Revisor
and Service User. The Management Server allows to collect audit data and monitoring. All
components are initialised in a secure network.
The communication server (represented by an additional genuscreen appliance) between
the genuscreen appliances and the genucenter management system avoids exposing the
genucenter to the Internet.
The firewall components have a local GUI which can be activated (i.e. when the
connectivity to the management system got lost). The GUI of the firewall components
supports two types of roles, i.e. Administrator and Revisor. The firewall components can
locally store log files.
6. Documentation
The evaluated documentation as outlined in table 2 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.
17 / 27
Certification Report BSI-DSZ-CC-1142-2020
7. IT Product Testing
Developer and evaluator tests combined, all configurations of the TOE being intended by
the current evaluation were tested or a rational for the validity of test results were provided.
Developer Tests
The test configuration in the genua laboratory includes five systems installed with the TOE.
Two of these systems are used as IPsec-Gateways. Two of these systems are used as
data source and data sink, therefore they need wide open filter rules. The fifth system
takes over the routing functions, but is also used to test filter rules. The tests itself are
running on the developer server which is also used for configuration functions. For testing
a set of physical and virtual machines is used.
The Security Target specifies eight assumptions about the environment of the TOE:
Assumptions A.PHYSEC, A.INIT, A.NOEVIL, A.SINGEN A.TIMESTMP, A.ADMIN,
A.HANET and A.REMOTE_AUTH. A.PHYSEC, A.NOEVIL, and A.REMOTE_AUTH are not
applicable to the test environment. A.ADMIN, A.INIT, A.SINGEN and A.HANET is given in
the test environment. A.TIMESTMP is given in all TOE configurations because of the
properties of the underlying operation system. All configurations were loaded from CD
respectively from USB.
For the most part the tests are automatically running under control of the configuration tool
and further testing framework of the development and QS testing lab. The tools also
provide the test results automatically. The test procedures are executable scripts (Ruby,
Perl or Shell). The developer uses two kinds of tests: Local tests and Live tests. Local
Tests need the developer environment and were executed inside the developer systems.
The tests itself are running on development servers, which also provides configuration
functions. Live tests are able to be performed on virtual machines as well as on real
physical systems.
Integrated scripts compare the actual result with the expected one. The output is the status
value OK respectively pass (if the real result is equal the expected one) or FAIL (if the real
result is not equal the expected one). Using the test scripts, the developer automatically
ensures that the entrance conditions and the dependencies between tests are considered.
The specified tests cover all security functions and the testing is performed against the
TOE design. All real test results are equal with the expected test results.
Independent Evaluator Tests
For the initial certification BSI-DSZ-CC-1085-2019:
The test equipment provided by the developer consists of several different firewall
components of different Hardware models, a CommServer (genuscreen XS) and two
instances of the TOE (genucenter L as well as genuscreen S; genuscreen M; genuscreen
L; infodas SDoT Server V3).
According to the Security Target, the evaluator installed the firewall components in a
separate administrator network. All components were installed on physical hardware, the
installation of the TOE on virtual machines is out of scope of the evaluated configuration.
For the operational configuration the firewall appliances and the management server were
integrated via a switch in one network. The test configuration was enhanced with internal
networks for each firewall component.
The configuration is consistent with the configuration in the Security Target.
18 / 27
BSI-DSZ-CC-1142-2020 Certification Report
To observe the behaviour of the firewall appliances, a console access was activated on
each appliance.
According to the assumptions identified in the Security Target the following is stated:
A.PHYSEC, A.NOEVIL, and A.REMOTE_AUTH are not applicable to the test environment.
A.ADMIN, A.SINGEN, A.INIT und A.HANET is given in the test environment. A.TIMESTMP
is given in all TOE configurations because of the properties of the underlying operation
system.
Testing covers the complex installation of all security functions. The main focus was the
implemented SIP Relay, the management system, cryptographic functions, random
number generator (RNG) and its entropy source (part of OpenBSD kernel) functions.
The repetition of the developer testing was performed in the developer laboratory.
The test results have not shown any deviations between the expected test results and the
actual test results.
For this re-certification:
Independent testing was performed at the developers site. Because of the slight adaptions
of the TOE compared to the last certified version, only a sampling of relevant tests were
performed.
The sampling of the tests was performed on revision 3 of a genuscreen S and a
genucenter L. Revision 2 was tested in the last certification in BSI-DSZ-CC-1085-2019.
The main focus of testing was the verification, installation and configuration of the updated
SIP relay, and the installation and verification of the genucenter and genuscreen software.
Furthermore a sampling of developers tests were repeated in this test meeting for
genuscreen S and genucenter L. By repeating the tests, the proceeding and results of the
provided developers tests could be checked. The developer tested all hardware revisions
in his developer testing.
The test results have not shown any deviations between the expected test results and the
actual test results.
Penetration Tests
For the initial certification BSI-DSZ-CC-1085-2019:
The evaluator has done an independent vulnerability analysis. As a result, additional
vulnerability tests have been designed. Penetration testing was performed as part of the
independent evaluator tests described in the previous chapter. Additionally, a source code
analysis was done.
No attack scenario with moderate attack potential was actually successful in the TOE’s
operational environment as defined in the ST, with all measures required by the developer
applied.
For this re-certification:
A rational was provided to show that the full vulnerability analysis of the initial certification
remains valid. Vulnerability tests have been performed as well. The focus of these
vulnerability tests were the updated SIP relay, thereby the SIP relay tests of the last
evaluation were repeated.
No attack scenario was actually successful in the TOE’s operational environment as
defined in the ST, if all measures required by the developer are applied.

Certification Report BSI-DSZ-CC-1142-2020
8. Evaluated Configuration
The TOE configuration consists of software on at least two firewall components
(genuscreen appliances) that work as network filters. Another machine to manage this
network of firewall components is called management system (genucenter management
system) which is a central component.
The firewall components are initialised on a secure network from the management system.
After initialisation, the firewall components can be distributed to the locations of the
networks they are protecting.
The genuscreen firewall components filter incoming and outgoing traffic for multiple
networks and can thus enforce a given security policy on the data flow. The firewall
components can work as bridges or routers. The firewall components can be used in an
optional high availability (HA) setup where the firewall components synchronize their
internal states.
At the same time, the firewall components can provide confidentiality and integrity for data
traffic passing between the networks. This Virtual Private Network function is achieved by
IPsec connections.
The TOE includes an optional SIP relay to allow the usage of a Session Border Controller
(SBC). An SBC is another network device and is not a part of the TOE. The SIP relay is
not included in the basic installation image but must be installed as an optional module at
the genucenter and deployed on the genuscreens.
The connection between genucenter and genuscreen is encrypted with SSH.
All HW and the platform OpenBSD Version 6.1 (in case of genucenter Management
System) resp. Version 6.2 (in case of genuscreen Firewall Components), kernel and user
space programs, HTTP/S server, DHCP server, TFTP server are not part of the TOE and
belong to the environment. The TOE contains cryptographic functionality. The
cryptographic algorithms are part of the TOE. This includes the random number generator
which is of class DRG.3 (see AIS20 [4]).
Please note that, as detailed in the Security Target [6] chapter 1.4.10, several functions
(such as CryptoCard, VPN to Other Appliances or Mobile Clients, L2TP VPN,
IKEv2/MOBIKE VPN, Dynamic Routing, genucenter HA, Remote Maintenance,
genucenter REST API) are out of scope of the evaluated configuration.
All information contained in the Security Target [6] and the guidance documentation ([8]
and [9]) have to be followed in order to set-up, configure and use the TOE in a secure
manner conformant to the evaluated configuration.
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.
The Evaluation Methodology CEM [2] was used for those components up to EAL 5
extended by advice of the Certification Body for components beyond EAL 5.
For RNG assessment the scheme interpretations AIS 20 was used (see [4]).
20 / 27
BSI-DSZ-CC-1142-2020 Certification Report
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.2, ASE_TSS.2 and AVA_VAN.4 augmented for this TOE
evaluation.
The evaluation has confirmed:
● PP Conformance: None
● for the Functionality: Product specific Security Target, Common Criteria Part 2
extended
● for the Assurance: Common Criteria Part 3 extended
EAL 4 augmented by ALC_FLR.2, ASE_TSS.2 and AVA_VAN.4
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 strength of the cryptographic algorithms was not rated in the course of this certification
procedure (see BSIG Section 9, Para. 4, Clause 2). But cryptographic functionalities with a
security level of lower than 100 bits can no longer be regarded as secure without
considering the application context. Therefore, for these functionalities, it shall be checked
whether the related crypto operations are appropriate for the intended system. Some
further hints and guidelines can be derived from the 'Technische Richtlinie BSI TR-02102'
(https://www.bsi.bund.de).
For details of the cryptographic algorithms that are used by the TOE to enforce its security
policy, please refer to the table in chapter 8 of the Security Target [6]. Any Cryptographic
Functionality that is marked in column 'Security Level above 100 Bits' of that table with 'no'
achieves a security level of lower than 100 Bits (in general context).
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 OSPs 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 of the
TOE is required and thus requested from the sponsor of the certificate.
The limited validity for the usage of cryptographic algorithms as outlined in chapter 9 has
to be considered by the user and his system risk management process, too.
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.
21 / 27
Certification Report BSI-DSZ-CC-1142-2020
● For a secure operation it is necessary to follow all recommendations of the genuscreen
Installations- und Konfigurationshandbuch [9] and genucenter Installations- und
Konfigurationshandbuch [8] and to follow all requirements for the environment described
in the Security Target. Especially all recommendations regarding configuration of packet
filter in combination of SSH-based VPN-tunnels should be read carefully, see also
genucenter manual chapter 5.7 "Nutzung der Sicherheitseigenschaften” respectively
genuscreen manual chapter D.6 "Nutzung der Sicherheitseigenschaften”. In case of a
lost appliance (e.g. theft), the procedures in the manual should be followed, see
genuscreen manual chapter C “Vorgehen bei Verlust einer Appliance” and genucenter
manual chapter D “Vorgehen bei Verlust einer Appliance”. Using SNMP, the
recommendations in chapter 6.4.2 “SNMP-Trap” should be followed. Before installation
the checksums of the software has to be verified, see genucenter manual chapter 2.1.4
“Verifizierung der Software” respectively genuscreen manual chapter 2.9 “Verifizierung
der Software”. This integrity verification includes the optional SIP module.
The assumptions to the IT environment in the Security Target state that the TOE operates
in a physically secure environment which prevents access from unauthorised users
(A.PHYSEC). Comparable protection mechanisms must be implemented to logically and
physically protect backup files of the genucenter management system. See the
recommendations given in genucenter-manual, chapter 2.5.
Administration and revision of the TOE should only be performed by personnel with solid
knowledge about networking (especially IP and TCP/UDP), packet filter firewalls and
secure use of public key procedures.
There should regularly performed inspections (revisions) of the TOE configuration,
especially of the packet filter rules. During those revisions, the procedures to import public
keys should be examined, too.
After installation of the firewall component by using the management system on each
component, PXE boot must be disabled (system hardening).
genucenter backups have to be stored in a secure place. Recommendations are
addressed in chapter 2.5 of the genucenter manual.
