Product Overview

The Cisco ® ACE Web Application Firewall (Figure 1) is the newest component of the Cisco Application Control Engine (ACE) family of products.
Many organizations are looking to increase efficiency and profitability through the implementation of new Web-based applications, Web 2.0 and SOA solutions. These new Web-based services provide greater flexibility and interactivity to customers, employees, and partners. At the same time, criminals have seized on exploiting these new, and often poorly secured services for such things as financial fraud, identity and data theft, denial of service attacks, and the spread of malware and remote-controlled agent software.
According to privacyrights.org, nearly a quarter of a billion records have been breached since 2005 in the US alone. In response, new and emerging regulatory requirements, like Sarbanes-Oxley, Graham-Leach-Bliley, HIPAA, PCI, Basel II, EU Data Privacy Regulation, J-SOX, and PIPEDA, in virtually every country and region in the world, place a special emphasis on protecting the access to, transmission of, and storage of sensitive information, such as the personal and financial information of customers and employees.
Of special interest is the protection of consumer financial and personal information. In response to increased identity theft incidents and security breaches, major credit card companies have collaborated to create the Payment Card Industry (PCI) Data Security Standard (DSS), which is a series of requirements to streamline and standardize how companies store and access credit card information.
The Cisco ACE Web Application Firewall helps organizations that store, process, and transmit credit card data to comply with the PCI DSS requirements. Because of its unique blend of HTML and XML security, the Cisco ACE Web Application Firewall provides a full compliance solution for the PCI 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 ( http://www.owasp.org/index.php/Top_10_2007 .)
The Cisco ACE Web Application Firewall provides full compliance with the latest PCI requirements by combining deep Web application analysis with high-performance XML inspection and management to truly address the full range of threats associated with all new Web application services. It secures and protects 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 (CSRF), buffer overflows, cookie tampering, and Denial of Service (DoS) attacks.
The Cisco ACE Web Application Firewall's integrated Extensible Markup Language (XML) firewall capabilities extend protection for traditional HTML-based Web applications to modern XML-enabled Web services applications. 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 is also a full proxy security solution that provides deep message-level inspections for both request and response traffic. This enables it to not only block attacks but also to cloak your Web applications from hackers. It can also enforce privacy policies by filtering outbound traffic to prevent leakage of sensitive data such as credit cards and personal identification numbers, such as passports or social security numbers.
The Cisco ACE Web Application Firewall software license can be upgraded to include the full Cisco ACE XML Gateway software, which provides a robust set of XML performance enhancement and management tools for XML-based software applications. The Cisco ACE XML Gateway helps to ensure that all XML messages are processed without compromising security, interoperability, or reliability. It enables businesses to efficiently secure, accelerate, and integrate XML Web services with the market's most extensive policy control and end-to-end performance, which allows customers to accelerate their time-to-market and gain competitive advantage in their businesses.

Secure, fast, and reliable HTML and XML applications require the capability to deliver assured throughput, high concurrency, low latency, and support for critical operations such as security and availability. The Cisco ACE Web Application Firewall offers these benefits by providing:

• Bullet-proof security for your custom applications

• Extensive set of Cisco validated signatures for known malicious patterns

• Understanding of Web applications to filter and allow only legitimate traffic

• Human-assisted learning to remove the guesswork from your security configuration

The Cisco ACE Web Application Firewall offers industry-leading security processing on a high-performance network appliance to accommodate your development and deployment requirements. Whether you are showing proof of concept, securing a small set of Web-enabled applications, or deploying a broad set of Web-enabled applications enterprise wide, Cisco provides the industry-leading Web application firewall solution that scales to meet your application security, availability and performance requirements.

Features and Benefits

• Dramatically reduce 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 SOAP and XML applications
