Do firewalls really work? By Tim Dickinson & Sven Radavics, Technology & Business magazine June 16, 2005 URL: http://www.zdnet.com.au/insight/security/soa/Do-firewalls-really-work-/0,139023764,139197113,00.htm
How secure is your network? Two Australian experts -- Sven Radavics, country manager, WatchGuard Australia and Tim Dickinson, country manager, SonicWALL Australia -- compare notes on their offerings.
Radavics: What do you believe are the key limitations of today's firewall solutions? Dickinson: These days having a firewall is simply not enough and when it comes to choosing a security solution provider, we strongly encourage customers to focus on the convergent elements offered by vendors and to have something that can support key business applications. That means making sure their solution:
Radavics: Everything should always start with a solid security policy whose goal is to support the network and IT business requirements. Without this you are only buying product, not a solution. At the gateway, we recommend using a fully integrated security appliance with zero-day protection and intelligent layered security. Many SMBs try to implement security systems by mixing disparate point solutions from several vendors. These products must all be purchased, installed, managed, and updated separately. This approach generates difficulties with interoperability, incomplete protection, and time-consuming testing and verifying patches across multiple technologies, all of which can slow a network's response to attacks. Organisations should also implement architectures that incorporate intrusion prevention to inspect and block traffic at the application layer, and enable access and activity to be controlled by the user and not just by the IP address. Customers should implement a solution which provides rich reporting, real-time monitoring, and multi-box management. For example, historical HTML-based reports can provide analysis of trends, while interactive, real-time monitoring tools allow IT managers to instantly identify problems and take preventive or corrective action to stop network threats.
Radavics:
What prevents SonicWALL from closing a sale?
Dickinson: How does WatchGuard ensure it provides flexible security options that suit a range of different types of customer business models? Radavics: Our three product lines meet a wide range of business needs with strong security built on a solid, trusted firewall and VPN foundation; Firebox X Peak for advanced network environments; Firebox X Core for corporate and branch offices; and the Firebox X Edge for small businesses, remote offices, and telecommuters. Firebox X Peak is capable of gigabit throughput and has the reliability, redundancy, traffic management, and port density that demanding, high-speed networks require. Firebox X Core customers can purchase model upgrades as their security needs change and obtain all the performance and functionality of the higher model in the line just as if they had purchased it originally. Firebox X Edge appliances integrate with Firebox X Core and Firebox X Peak appliances to extend perimeter security to the furthest points of the corporate network. Radavics: What do you see as the return on investment from a firewall solution? Dickinson: This is an excellent question. In response to customer demand, we have developed a dedicated security management solution -- our Content Security Manager -- that allows companies to optimise productivity when providing employees with access to the Internet for work purposes. Time and again our customers have told us that when deploying our Content Filtering Solution to restrict employees' access to particular sites at particular times of the working day, on a case-by-case or group basis, their productivity is maximised. They see this as a real, tangible return on their investment. This helps them understand that a security solution can be a productivity and enablement tool. It is not just about stopping attacks -- it's about ensuring the uptime and availability of networks around the clock. Dickinson: How is WatchGuard guaranteeing that it has a depth and breadth of quality engineers available through channel partners locally to serve the needs of customers who want to outsource their network security? Radavics: Our channel partners in Australia include Firewall Systems, LAN Systems, and WhiteGold Solutions. Firewall Systems runs training certification courses throughout the country while our systems engineers provide regular, local quick-start and advanced training. Channel partner engineers also have access to the WatchGuard LiveSecurity Service, a renewable subscription to a suite of services, including access to security experts, threat alerts, software updates, technical support, and security broadcasts. Channel partners can share this information with their customers, as an added benefit to them. Another partner, VOIP, also provides their security expertise through the channel through their managed security service based on WatchGuard products.
Radavics:
What trends do you see in cybercrime? Radavics: WatchGuard pioneered the "firewall appliance" concept to address the need for a high-performance, easy-to-use, robust Internet security solution that SMEs could afford and manage. Our Intelligent Layered Security architecture protects against emerging threats effectively and efficiently, and provides the flexibility to affordably upgrade and integrate additional security functionality as a business grows. This is how we help small businesses to enhance their initial security investment and realise a much lower total cost of ownership (TCO). In addition, an intuitive Web-based user interface and quick-start wizards make it easy to set up and configure. Dynamic stateful packet inspection delivers SMEs commercial-grade security that protects networks while managed desktop antivirus provides centrally managed desktop protection against known viruses, Web attacks, and WAN failover. Radavics: Are there any benefits to be had from outsourcing IT security? Dickinson: "Security without hassle" is a winning proposition for customers and the growing trend is for SMEs to outsource this specialist area. According to IDC this is a fast-growing global trend and it is certainly hugely popular in the local SME market, as SonicWALL has seen. Threats to network security are becoming increasingly complex, and companies need to be on security alert if their data and voice networks are to remain uncompromised. With the outsourced model they have 24x7 access to the breadth and depth of engineering specialist expertise their network requires but at a fraction of what it would cost to employ this specialist in-house. Dickinson: How does WatchGuard feel about using Linux as its operating system now that the Fortinet GPL violations have gone to litigation? Radavics: We have been using Linux since 1996. The WatchGuard design process releases all modifications to the operating system kernel back into the public domain. This process enables the Linux development community to scrutinise the changes we have made to ensure that the modifications are stable and reliable. The WatchGuard Firebox System software code that runs on the modified kernel remains proprietary to WatchGuard Technologies. This design approach allows WatchGuard to deploy a secure appliance over an aggressively debugged operating system at a fraction of the total cost of other network security approaches.
Radavics:
What is your opinion of the recent discussion regarding an Australian Government-sponsored IT Security Certification scheme? Radavics: We already have a common management tool for our Firebox X range of products which our customers love. We also have a simpler Web-based interface for organisations who choose our Firebox X Edge for standalone/SOHO-type deployments. Our GUI is our strength.
