Many applications are vulnerable to such attacks because application developers do not consistently employ secure coding practices. Barracuda Web Site Firewall is designed to combat all attack types that have been categorized as significant threats, including: • Cross Site Scripting (XSS) • SQL injection flaws • OS command injections • Site reconnaissance • Session hijacking • Application denial of service • Malicious probes/crawlers • Cookie/session tampering • Path traversal • Information leakage A Single Solution to a Multifaceted Problem Online Web-based applications are increasingly at risk from professional hackers who target such applications in order to commit data theft or fraud. Being compromised can damage an enterprise’s reputation, result in loss of customers and impact the organization’s bottom line. In addition, companies that transact online are faced with a host of growing industry regulations such as the Payment Card Industry Data Security Standard (PCI DSS), which mandates that all enterprise and Web applications handling credit card and account information must undergo an extensive and costly audit of custom application code. The alternative to satisfy PCI DSS compliance is simply installing a Web application firewall. The combination of these factors along with banking industry PCI DSS compliance concerns, creates demand for a more technologically and cost-effective risk protection solution for online Web applications. Backed by the worldwide leader in email and Web security appliances, the Barracuda Web Site Firewall will continue to dominate the market by breaking technology barriers.

Barracuda Web Site Firewall Features

Traditionally, security has been considered a network issue, where system administrators lock down host computers through a network firewall. While a typical network firewall can help restrict traffic to HTTP and HTTPS, this traffic can contain command exploits leveraging vulnerabilities in the Web application itself that can result in data leakage, site defacement and other attacks by hackers that compromise both the privacy and integrity of vital data. Businesses of all sizes that operate their own Web applications should ensure that their Web sites are protected against application vulnerabilities. The Barracuda Web Site Firewall provides complete protection of Web applications and is designed to enforce policies for both internal and external data security standards, such as Payment Card Industry Data Security Standard (PCI DSS). At the same time the Barracuda Web Site Firewall 460 and higher models feature a comprehensive set of application delivery capabilities designed to improve the performance, scalability and manageability of today’s most demanding data center infrastructures.

Comprehensive Web Site Protection

The Barracuda Web Site Firewall proxies all of your Web site traffic, providing complete protection in front of your Web sites. Capabilities include: • HTTP protocol compliance. At a basic level, the Barracuda Web Site Firewall verifies that all inbound requests comply with the HTTP specification. For example, inbound requests with more than one Content-Length header are typically the basis of HTTP request smuggling attacks; therefore they are illegal according to the HTTP specification and are blocked automatically. • Protection against common, high-visibility attacks. Hackers can take advantage of vulnerabilities in your online Web forms to attack your applications. The Barracuda Web Site Firewall protects your Web applications against SQL injections, OS command injections and cross-site scripting attacks. • Protection against attacks based on session state. The Barracuda Web Site Firewall protects your Web applications against any attacks based on session state, such as forms tampering or cookie tampering. • Outbound data theft protection. In addition to inspecting the request traffic, the Barracuda Web Site Firewall also inspects all outbound packets for any data pattern expressible as a UNIX-style regular expression. Built-in policies protect all major credit cards and U.S. Social Security number patterns and new data patterns can be added at any time. Inspection for outbound leakage of these patterns can be applied to security policy on-the-fly. • Web site cloaking. To prevent hackers from doing reconnaissance on your Web infrastructure, the Barracuda Web Site Firewall automatically strips identifying banners of Web server software and version numbers out of all transactions. • Anti-crawling. While some Web crawlers, such as search engines are often desirable, you may wish to prevent all other users from downloading your entire site. The Barracuda Web Site Firewall can easily identify and allow legitimate crawlers while blocking more malicious ones. • Fine-grained control. The Barracuda Web Site Firewall features automatic fine-grain rules creation based on both HTTP requests and responses down to the level of individual HTML elements. • Application denial of service (DoS) protection. By validating input limits for online form fields, Web applications and sites are protected against the SQL injections, OS command injections or form field-based attacks. Fine-grain control on all points prevents hackers from instigating these common attacks.

Application Access Control

The Barracuda Web Site Firewall implements a single point for policy enforcement and control, which includes authentication to ensure that users are known, access control policy for resources and protection against data leakage. Capabilities include: • PKI support. By providing a full PKI infrastructure, the Barracuda Web Site Firewall can act as a Certificate Authority, including participating in a certificate trust chain. • Cookie tampering. The Barracuda Web Site Firewall fully terminates and proxies every connection to insulate each unique user session from exposure and can stamp or encrypt the session cookies. Also included to prevent cookie tampering is the ability to ensure that all hidden or read-only form fields are not changed by the user.

Application Delivery and Acceleration

In addition to the comprehensive security benefits of the Barracuda Web Site Firewall, there are also additional operational capabilities available in the Barracuda Web Site Firewall. Capabilities include: • SSL offloading. The Barracuda Web Site Firewall includes SSL offloading, streamlining the encryption and decryption of SSL traffic to quickly process secure online transactions without additional burden on any servers. • SSL acceleration. The Barracuda Web Site Firewall includes hardware-based SSL acceleration, offloading back-end servers from the computational burdens of encrypting and decrypting secure Web traffic. • Load balancing. The Barracuda Web Site Firewall includes integrated load balancing capabilities to distribute traffic among multiple back-end servers. It supports both Layer 4 and Layer 7 cookie persistence and includes support for Layer 7 content switching based on URL pattern, parameter or HTTP header fields. • High Availability. When inline in Bridge-path, the Ethernet Hard Bypass ensures reliable application delivery even with a single Barracuda Web Site Firewall. For Web applications with stringent security requirements, the Barracuda Web Site Firewall may be installed in a redundant pair configuration, providing real-time application state replication so that security and user sessions will not be compromised during a failover event.

Logging, Monitoring and Reporting

The Barracuda Web Site Firewall features advanced capabilities to provide immediate feedback to the operations team that deploy, manage and secure mission critical applications. Capabilities include: • Comprehensive logging. The Barracuda Web Site Firewall maintains a rich set of logs on the appliance, including system activity, Web Firewall activity, Web services activity, network firewall activity and traditional Web logs. • PCI reports. The Barracuda Web Site Firewall provides an easy-to-read snapshot of common application attacks, critical for securing credit card important and providing compliance to PCI DSS requirements. • Syslog support. The Barracuda Web Site Firewall forwards logs to a syslog server for centralized and persistent storage or analysis by a third party tool.
