Certification Report1.BSI-DSZ-CC-0966-2015Executive SummaryThe TOE genuscreen 5.0 is a distributed stateful packet filter firewall system with VPNcapabilities and central configuration. It provides basic IPv6 support and protects networksat the border to the Internet by filtering incoming and outgoing data traffic. It protects dataflow between several protected networks against unauthorised inspection andmodification. It consists of software on a number of machines (genuscreen appliances)that work as network filters, hereafter called firewall components, and the managementsystem (genucenter management system), a central component to manage this network offirewall components.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 thenetworks they are protecting.The genuscreen firewall components filter incoming and outgoing traffic for multiplenetworks and can thus enforce a given security policy on the data flow. The filter isimplemented in the kernel of the firewall components’ operating system, OpenBSD. Thefirewall components can work as bridges or routers.The firewall components can provide confidentiality and integrity for data traffic passingbetween the networks. This Virtual Private Network function is achieved by IPsecencryption and authentication mechanisms. Alternatively, an encrypted tunnel not usingthe transport layer but the application layer can be build up with SSH connections.Interfaces of the firewall components can be classified at level high or low. Traffic oninterfaces with a low classification is not transferred as cleartext.The management system component provides administrators with a Graphical UserInterface (GUI) to initialise and manage the firewall components from a central server. Themanagement system also allows collecting audit data and monitoring.The TOE contains cryptographic functionality. The cryptographic algorithms are part of theTOE. 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 doesnot 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 certifiedProtection Profile.The TOE Security Assurance Requirements (SAR) are based entirely on the assurancecomponents 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 4augmented by ALC FLR.2, ASE TSS.2 and AVA VAN.4.The TOE Security Functional Requirements (SFR) relevant for the TOE are outlined in theSecurity Target [6], chapter 6. They are selected from Common Criteria Part 2 and some ofthem are newly defined. Thus the TOE is CC Part 2 extended.The TOE Security Functional Requirements are implemented by the following TOESecurity Functionality:TOE Security FunctionalityAddressed issueSF PFPacket Filter12 / 34

The following securtiy policies are defined for the TOE.Five policies are explictly defined: FW-SFP: creation, modification, deletion and application of firewall security policy rules. RS-SFP: interface classification. IKE-SFP: cryptographic functions in relation to the key management of the VPNconnections between the firewall components. SSH-SFP: flow control functions in relation to the communication between themanagement system and the firewall components. SSHLD-SFP: flow control functions in relation to the SSH launch daemoncommunication between the firewall components.All other policies are implictly defined and cover the following areas: IPSEC: flow control functions in relation to the VPN connections between the firewallcomponents. Administration Policy (implemented by SF ADM). Identification and Authentication Policy (implemented by SF IA). Audit Policy (implemented by SF AU). General Management Facilities Policy (implemented by SF GEN). Random Number Generation (implemented by FCS RNG).4.Assumptions and Clarification of ScopeThe Assumptions defined in the Security Target and some aspects of Threats andOrganisational Security Policies are not covered by the TOE itself. These aspects lead tospecific security objectives to be fulfilled by the TOE-Environment. The following topics areof relevance: OE.PHYSEC, OE.INIT, OE.NOEVIL, OE.SINGEN, OE.TIMESTMP,OE.ADMIN, and OE.HANET. Details can be found in the Security Target [6], chapter 4.2.15 / 34

Certification Report5.BSI-DSZ-CC-0966-2015Architectural InformationThe TOE is the software part of the firewall system genuscreen 5.0 developed by genuagmbh.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 thefirewall components.The Management Server allows authorised administrators to configure filter rules andprotection policies on the firewall components by use of a web-based graphical userinterface (GUI) at the Management Server. It also enables authorised administrators toupdate the software on the firewall components. The GUI must be used from a trustedmachine connected to the management Server through a trusted network.After installation, all communication between the Management Server and the firewallcomponents is protected by Secure Shell (SSH) transforms against eavesdropping andmodification.The firewall components employ IPsec and SSH-based encryption and authentication toprotect 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 (forgenuscreen) where the firewall components synchronize their internal states. In case ofone system breaks down the function of this component is resumed by the other.Management consists of definition / modification and transmission of firewall policies andsecurity policies for network traffic. The GUI also allows transfer of audit data from thefirewall components.The TOE provides VPN and firewall functionality and is easy to manage. It protectsnetworks at the border of the Internet by filtering data. It also protects the data flowbetween several protected networks against unauthorised inspection and modification. Itconsists of software on at least two machines (genuscreen appliances), which filterincoming and outgoing traffic for multiple networks. The firewall components (genuscreenappliances) provide confidentiality and integrity for data traffic passing between thenetworks by using IPsec encryption / authentication functionality. Alternatively, anencrypted tunnel using the application layer can be build up from SSH connections. Thiscomposition is referred to as the SSH launch daemon. The firewall components can workas bridges and routers. Interfaces of the firewall components can be classified optionally.Traffic sent to or received from interfaces with classification is not transported in clear text.Cryptographic operations are part of the TOE. This includes the random number generatorwhich is of class DRG.3 (see AIS20 [4]). The TOE provides basic IPv6 support.The GUI of the management server supports three types of user roles, i.e. Administrator,Revisor and Service. 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) betweenthe genuscreen appliances and the genucenter management system avoids exposing thegenucenter to the Internet.The firewall components have a local GUI, too, which can be activated (i.e. when theconnectivity to the management system got lost). The GUI of the firewall components16 / 34
