4 Test Objectives Through a series of rigorous tests, West Coast Labs is providing a thorough examination of all the main technology components in the devices under test in a real world test environment to establish the level of functionality and performance of both. For the purposes of this Product Test Report, West Coast Labs tests the following technologies: Firewall VPN Anti-Spam URL Filtering IPS West Coast Labs engineers test and evaluate each device in a controlled environment. Throughout the test period, each product has internet access and is configured as recommended to update online. The testing environment mirrors that of a small to medium sized business and the internal interface of the firewall is connected to a 100Mbs network, and traffic loads are set accordingly. Products are tested in accordance with the functionality and performance criteria, which form the Checkmark certification programs for Firewall, VPN, IPS, URL Filtering and Anti-Spam. (See Appendix D). 4

5 Checkmark Certification Upon completion of all testing within each UTM technology subset, individual product results are manually analyzed and confirmed, and Checkmark accreditation is awarded on achieving the following standards: Checkmark Anti-Spam Certification Premium 97% and over Catch Rate Standard 90% and over Catch Rate Checkmark Anti-Virus Certification 100% Detection Checkmark Anti-Spyware Certification 100% Detection Checkmark IPS Certification 100% Detection and Prevention Rate Checkmark URL Filtering Certification Premium 100% adherence to policy Standard 95% and over adherence to policy Checkmark Enterprise Firewall Certification 100% adherence to policy Checkmark VPN Certification 100% adherence to policy 5

6 The Product Introduction The Firebox X family of UTM solutions consist of Peak, Core, and Edge e-series models that address an entire gamut of security issues relevant to small, medium, and large enterprises. The solutions ship in the form of gateway appliances that are specifically designed to automatically counter zero day threats using advanced proxy technologies and policy controls, and include antivirus, anti-spyware, IPS, VPN, URL content filtering, anti-spam, and firewall modules. The higher end appliances boast multiple Gigabit Ethernet ports, while all e-series devices are designed for optimum throughput rates and performance. The Core and Peak models have an integral LCD display panel. 6

7 Installation and Configuration The primary method of installation is via an easy to operate set-up wizard. All configuration activities are ordinarily carried out using either a standard web browser to access an SSL-encrypted web page for the Edge device, or via the dedicated installation of the WatchGuard System Manager (WSM) Windows application for control of the Core and Peak models. West Coast Labs opted to manage all Firebox X devices using a single instance of the WSM in order to provide continuity between the test set ups. Network interfaces were configured in internal (LAN), external (WAN), and optional modes, to match test requirements and available IP address space. Using the graphical point and click functionality of the WSM, West Coast Labs quickly set-up and configured the appropriate proxies to scan HTTP, POP3, and SMTP traffic for malware, in line with device capabilities. The devices ship with a complete set of useful and accurate documentation that proved effective during the installation process, and throughout the subsequent test period. 7

8 Operations and Features The devices each contain an anti-malware component that works seamlessly with other UTM modules to provide a powerful protection barrier against a wide range of threats, including viruses, spyware, trojans, DoS atttacks, SQL injections, worms, web exploits, and buffer overflows*. The integral spamblocker engine proved effective at preventing unsolicited from reaching end-users. Once it is enabled and an appropriate policy defined, the spamblocker module intercepts and checks all routed through the devices. Supported protocols include SMTP and POP3. The appliances ship with a URL content filtering module known as WebBlocker. This module operates as an HTTP proxy server, providing a full-featured and accurate web filtering mechanism. Using the policy engine, Administrators can define categories of URL that end-users are unable to access from within the corporate network. Specific URL exceptions are easily configured, providing organisations with the ability to fine tune access restrictions to their individual requirements. The Firebox X family uses a powerful, flexible firewall engine that, when coupled with the inbuilt fine-grained control of the policy module, provides a comprehensive and proven defence against common forms of automated and manual attack. The firewall, policy management, and ruleset configurations proved simple to set up and adjust via the management console. The firewall is deployed in a secure posture by default. Each device provides the inherent ability for a VPN to be configured, allowing secure connections to be established between any IPSec 8

9 and PPTP compliant products on distinct internal networks, in a simple and intuitive fashion. Remote Mobile User VPN (MUVPN) and manual modes are also optionally available, providing added flexibility while catering for a wide range of deployment scenarios. All VPN set-up and management is carried out using the standard management console. A tightly coupled, easily configured IPS engine is also included on each appliance. This component is designed to prevent threats from traversing the device and reaching the protected network. The engine actively and,if required, automatically blocks attack sources either permanently or on a temporary basis, with black and white lists available for more granular control. The WSM contains a Policy Manager component that displays each packet filter and proxy as a graphical icon, to represent a policy. It is straightforward to configure the source and destination for network traffic, and to specify whether this traffic is allowed or denied. Associated rules can also be set for logging and notification functionality. The devices include a number of pre-configured packet filters and proxies out of the box. For example, should an end-user require a packet filter for all telnet traffic, they can simply select the pre-defined telnet policy and modify the parameters to suit their individual needs. In addition, end-users also have the option to create custom packet filters or proxies and set the ports, protocols, and other parameters to match their requirements. * West Coast Labs were not required to formally test anti-virus and antispyware functionality to any Checkmark standard. 9

10 Reporting The WSM incorporates a real-time connection monitoring module, known as HostWatch, to display an operational picture of live network communications. This feature is potentially useful to administrators as it provides the ability to view current activity, allowing inappropriate connections to be terminated, thus further protecting network integrity. In addition to HostWatch, the WSM includes a powerful reporting system, allowing administrators to perform comprehensive analyses of network throughput, identification of security threats, and to assess end-user behaviour. The reporting engine supports data export in a number of formats, such as HTML and XML, thus ensuring flexibility and compatibility with a variety of third-party reporting systems. There is also a specific NetIQ compatible export format. 10

11 Results Anti-spam functionality was tested by pointing a live internet domain feed at the appliances, this feed was comprised of spam, ham (genuine), and gray . Depending on the particular appliance, both SMTP (Core and Peak) and POP3 (Edge) based s were processed from the external feed and relayed to an internal mail server. The Core and Peak devices use the same firmware and produced the following results. Type of Mail Detected as Genuine Detected as Spam GENUINE 100% 0% SPAM 6% 94% The Edge anti-spam test results are shown in the table below Type of Mail Detected as Genuine Detected as Spam GENUINE 100% 0% SPAM 4% 96% Throughout firewall testing, the appliances successfully blocked all spoofing, DoS, and malformed packet attacks as well as correctly logging the associated events. The appliances simultaneously allowed all legitimate network traffic to traverse each device under test and further blocked network probes that attempted to discover which services were active. IPS testing proved that the devices were equally as competent in preventing repeated attack attempts using different threats from the same source IP address, as they were in protecting against different threats from multiple source IP addresses. It is also worth noting that an extensive range of threats are set to an automatic block in 11

12 the default policy as an extra layer of protection. Testing involved attempting to exploit vulnerable computers within the protected network emulating a real-world attack from an internet-based source. West Coast Labs tested the effectiveness of the WatchGuard WebBlocker URL filtering module, by configuring the filtering policy to block certain undesirable content, while simultaneously allowing all other content. To aid testing in this area, a proprietary in house URL loader application based upon a well known web browser was used in conjunction with a manually harvested and verified set of several thousand URLs. Each device correctly blocked all content types specified by the policy, while allowing legitimate traffic through to the requesting end-user computer. For VPN testing purposes, West Coast Labs configured an IPSec VPN between the devices under test, emulating a real-world connection between a branch office and a remote office. West Coast Labs then applied a policy to only allow specific access to resources or services; web, , and ftp servers on both the branch and remote networks. Additional services were active on both networks, however, all access to these services was denied. West Coast Labs subsequently tested that the access policy was operating correctly and that only the specified services were allowed, while all additional, non-specified services were denied. Port probes, network traffic analyzers, and other commonly used security tools and techniques were used in attempts to circumvent policy and to ensure that all data passing through the VPN connection were encrypted. West Coast Labs is pleased to award the WatchGuard Firebox X e- Series the Anti-Spam, Enterprise Firewall, IPS, URL Filtering, and VPN Checkmarks. 12

13 Conclusion The devices share a number of underlying software components and are similar in functionality. In addition to being systematically easy to use, configure, and manage, the Firebox X e-series provide effective protection against multiple real-world security threats. All devices benefit from thorough, well-written, and accurate documentation, as well as a secure internet support portal that provides simple, intuitive account management. In addition, an easy to use product upgrade area is also provided online that allows for the effortless upgrade of features and functionality. This is achieved by simply downloading and applying a license key to the product, as and when required and is an especially beneficial service to corporate customers and system administrators who have other calls on their time. The Firebox X e-series successfully blends versatility and performance with simple and effective management features, to produce a range of powerful and practical solutions, potentially benefiting businesses of any size. 13

23 Appendix D Test Methodology and Specifications Firewall Test Environment The test environment will consist of three distinct networks: the external (Internet), DMZ and internal (protected). The external network may include a telnet host, Web server, FTP server, DNS server and a "hacker" client to simulate the internet. The DMZ network may include a Web server and FTP server. The internal network may include a DNS server, SMTP server, file/print server, Web server and a "hacker" client. Machines on the internal and DMZ networks are not configured in a secure manner: they rely totally on the protection of the firewall. The firewall is the only link between the DMZ, internal & external networks. The link between the firewall and the external network is via a simple router. No packet filtering will be configured on this router: all protection must be provided by the firewall. Network monitors, protocol analysers and security monitors are employed on the external, DMZ and internal networks. Firewall Configuration The firewall is to be configured to provide the various services and enforce the various restrictions specified in this document. All firewalls are to be provided initially with an "out of the box" configuration, although vendors will be invited to remotely access their products if they wish to provide a best fit configuration. Network ranges will be provided to vendors as appropriate. No patches or configuration options will be allowed which are not available to the general public either in a current release or via a recognised and generally available support source. The configuration of all machines on the three networks will remain constant between tests. 25

24 Appendix D Test Methodology and Specifications Firewall Service Configuration The firewall is to be configured to allow the following outbound services: Internal to External: DNS, FTP (active and passive), HTTP, SSL/HTTPS, SSH, Telnet, SMTP Internal to DMZ: FTP, HTTP, SSL/HTTPS, SSH External to Internal: DNS, SSH, and SMTP External to DMZ: DNS, FTP, HTTP, SSL/HTTPS, SSH, SMTP DMZ to Internal: syslog, SNMP Firewall Test Specifications The testing is designed to ensure that the firewall technologies under test achieve a basic level of protection against a number of common hostile attacks, from both inside and outside the organization. A range of tests will be carried out using a variety of firewall scanning tools: these will be configured with full knowledge of both the firewall and network configuration: Test that all specified outbound services (and no others) are available from internal clients. Test that all specified inbound services (and no others) are available to external clients. Test that the firewall management console is not available to any users unless authenticated. Test that the firewall is resistant to a range of known Denial Of Service (DOS) tests. Test that the firewall does not allow uncontrolled access to either the internal or DMZ networks. Test that the underlying OS is hardened and not vulnerable to known OS-specific attacks. 26

25 Appendix D Test Methodology and Specifications Tests will be repeated in the following manner: Probe the internal network from the Internet Probe the DMZ from the Internet Probe the firewall from the Internet Probe the external network from the internal network (test security policy) Probe the DMZ from the internal network Probe the firewall from the internal network Management of the firewall will be evaluated using the following criteria: Local console must be secure. Management console should not be open to the external network. The firewall configuration should be fully protected and tamper proof (except from an authorised management station). Authentication should be required for the administrator for local administration. Authentication and an encrypted link should be available for remote administration. All attacks should be logged with date and time. 27

26 Appendix D Test Methodology and Specifications VPN Test Environment The VPN Test Environment will be based on the specification for Firewall as shown above, although another network will be specified as a Remote Office (RO). This may contain a telnet host, DNS server, SMTP server, FTP server, file/print server, Web server and client machines. Network monitors, protocol analysers and security monitors will also be deployed on the RO network. VPN Configuration and Service Configuration Initial configuration of the RO firewall should allow no inbound traffic to services hosted on the RO network. Clients on the RO should have access to the DNS, HTTP and SSL/HTTPS servers on the External network. The initial configuration of the VPN should allow unrestricted traffic flow between the RO and the main Internal network. This should include as a minimum ICMP, DNS, FTP (active and passive), HTTP, SSL/HTTPS, SMTP. 28

27 Appendix D Test Methodology and Specifications VPN Test Specifications The testing is designed to ensure that VPN technology achieves a basic level of security performance in that it: Allows a secure point-to-point link between two networks and between a roaming client and a network (optional) Provides authentication and access control mechanisms to restrict resource access on a per-user or per-group level Provides packet filtering or proxy services within the tunnel to restrict tunnel traffic to specific protocols or source/destination points Enforces a reasonable level of encryption and data integrity. Penetration Tests A range of penetration tests will be carried out using commonlyavailable scanning tools All tools will be configured with full knowledge of both the VPN and network configuration: Check that VPN management console is not available to any users unless authenticated and that the remote management link (if available) is encrypted or can be disabled Check that the VPN configuration is fully protected and tamper proof and that the VPN is resistant to a range of known Denial Of Service (DOS) attacks Check that the VPN has no known vulnerabilities and that it does not allow uncontrolled access to the networks behind it if traffic is restricted (see Services) Check that the VPN does not pass mis-configured packets to the networks behind it if traffic is restricted (see Services) and that the VPN correctly enforces access control policy on a per user and/or per group basis 29

28 Appendix D Test Methodology and Specifications Additional Tests Stage 1: Probe the VPN from the protected network with no tunnel established Stage 2: Probe the VPN from the external network with no tunnel established Stage 3: Attempt to establish tunnels using incorrect credentials Stage 4: Establish a valid tunnel (gateway-gateway and optionally client-gateway) and ensure that data is being encrypted Stage 5: Probe the remote network from the local network with valid gateway-gateway tunnel established attempt to violate tunnel traffic policy (eg. pass prohibited protocols, etc.) Stage 6: Probe the remote network from the local network with valid client-gateway tunnel established attempt to violate tunnel traffic policy (eg pass prohibited protocols, etc). Stage 7: Probe the remote network from the local network with valid gateway-gateway tunnel established attempt to violate access control policy (eg. user to access restricted resources). Stage 8: Probe the remote network from the local network with valid client-gateway tunnel established attempt to violate access control policy (eg. user to access restricted resources). 30

29 Appendix D Test Methodology and Specifications Management Management of the VPN will be evaluated using the following criteria: Local console must be secure and the Management console should not be open to the external network The VPN configuration should be fully protected and tamper proof (except from an authorised management station) Full authentication is required for the administrator for local administration Full authentication and an encrypted link is required for remote administration. If the remote link cannot be encrypted, there should be the ability to disable it. IPS Test Environment The network structure will be the same as for the VPN testing (if the DUT supports it, otherwise it should be the same as for firewall testing) with deployments of Network monitors, protocol analysers and security monitors on each network. Configuration The configuration of the DUT should be the same as the VPN testing (if the DUT supports it, otherwise it should be the same as for firewall testing). 31

30 Appendix D Test Methodology and Specifications Testing The IPS testing module is designed to ensure that the Intrusion Detection and/or Prevention technology contributes to a basic level of protection for an organization against hostile attacks. All IPS testing will be conducted with full knowledge of the configuration of the DUT. The testing will include a variety of different testing methodologies using both proprietary and established tools and code. Further exploration and attempted exploitations will take place dependant upon the DUT and results received from scans made. The IPS will be expected to monitor all traffic between the external and internal networks. Machines on the internal network are not configured in a secure manner. Network monitors, protocol analysers and security monitors are employed on the external and internal networks. The configuration of all machines remains constant between tests. A full range of tests will be carried out using tools, which will be configured with full knowledge of the network configuration. Tools used will include port scanners and vulnerability testers. Attacks will be launched including denial of service attacks and targeted buffer overflows. The internal network will also be subject to attack using spyware, worms and Trojans drawn from the West Coast Labs AV, Spyware and Trojan test suites. The IPS will be tested for reactions to: multiple, varied attacks (flood and swarm). obfuscated URLs and obfuscated exploit payloads speed adjustments in packet sending fragmented packets The testing will also review IPS logs and alerts, matching them to vulnerability scans. They will also be matched to password cracking activity. 32

31 Appendix D Test Methodology and Specifications Anti-Spam test Environment WCL has a number of domains available which act as honeypots for spam, receiving genuine, not canned spam. These domains receive varying levels of spam and are intended to mirror different environments. Within each domain are designated user accounts with a variety of practices and needs. Test Methodology During the course of testing, test engineers use several different internal and external accounts to send s that simulate real life transactions common in a business environment. These include requesting meetings, distributing notifications to groups and sending non-business related social s. s are also sent from web-based accounts to simulate external users sending non-business related s and home workers. Individual user accounts are subscribed to several mailing lists and daily newsletters for grey mail purposes. Each solution is configured initially to fit in with the test network using the vendor s recommendations and is placed into the stream of live mail to ascertain how it copes in an out-of-the-box situation. The only alteration made to standard working practices is that all s should be forwarded on (although with altered headers or some sort of flag marking the offending mail as spam) to allow for later classification. For ascertaining the level of performance, each solution will receive a set number of s. These are then classified by hand into genuine, spam and grey mail by test engineers with full knowledge of the mailing lists that have been previously signed up for. These figures are then compared with the figures given by the solution to give an overall detection rate. 33

32 Appendix D Test Methodology and Specifications Each solution will be assessed in three specific areas Management/ Administration, Functionality, and Performance. 1. Management/Administration. Ease of Setup/Use; Logging and reporting function; Rule creation. Customization; Content Categories; Product Documentation 2. Functionality Processing; Allow/Blocking of ; Quarantine Area; Blacklist/ Whitelist 3. Performance Volume or % of spam detected; False positive rate Spam incorrectly passed thru; Legitimate mail blocked 34

33 Appendix D Test Methodology and Specifications URL Filtering Test Environment The tests replicate a number of hits on sites or s received that fall outside of a prescribed Acceptable Usage Policy, along with providing genuine sites as a control group. URL Filtering Test Methodology TEST I - A proprietary piece of software loads in a list of URLs from a file. This switches through the list changing web page every 6 (six) seconds until it either runs out of URLs or receives an END command. The HTML code from each web page is appended to a log. The designated test engineer will then look through these logs to ascertain if any pages have been passed through the solution. TEST II - The list from TEST I is re-run through the software. This is accompanied by two human operators manually following a prespecified list of URLs in a pre-specified order, and also by a background load provided by specialist hardware. The logs are then appended again to a log file and will be checked further. Test Specifications Basic assessment of the solutions under test will consist of attempts to access material via the web in contravention of the security policy. A standardised user session will be employed for this purpose with reproducible http requests being generated. It is expected that attempts to access web sites outwith the terms of the security policy will be blocked, and that all such attempts will be logged and recorded. 35
