The Cisco® ACE Web Application Firewall is the newest addition to the Cisco ACE family of products. It provides a full-proxy firewall solution for both HTML and Extensible Markup Language (XML)-based Web applications.

Because of its unique blend of HTML and XML security, the Cisco ACE Web Application Firewall provides a full compliance solution for the Payment Card Industry (PCI) Data Security Standard (DSS) version 1.1's requirements in sections 6.5 and 6.6.

Section 6.6 in particular mandates that any organization handling, processing, or storing credit card information must install a Web application firewall by June 30, 2008 to protect applications against the OWASP Top 10 attacks (

The Cisco ACE Web Application Firewall provides full compliance with the latest's PCI requirements by securing and protecting Web applications from common attacks, such as identity theft, data theft, application disruption, fraud, and targeted attacks. These attacks may include cross-site scripting (XSS) attacks, SQL and command injection, privilege escalation, cross-site request forgeries (CSRFs), buffer overflows, cookie tampering, and denial of service (DoS) attacks.
Additionally, the Cisco ACE Web Application Firewall's integrated XML firewall capabilities extend protection for traditional HTML-based Web applications to modern XML-enabled Web services applications to provide the broadest compliance with PCI standards. The security for XML data includes XML threat mitigation such as validating XML content to block message processing policy violations in your Web services' application traffic.
The Cisco ACE Web Application Firewall enables organizations to:

• Dramatically reduce their exposure to expensive Web-based attacks on mission-critical applications

• Deploy secure Web projects in a fraction of the time and cost of competitive solutions

• Simplify ongoing Web security management through the ability to work with SOA and XML applications
