The Barracuda Web Application Firewall: XML Firewall

Télécharger le PDF


SOAP/XML or web services based applications are industry standards by which organizations streamline business processes, enhance information sharing efficiency and reduce application integration costs. Available in Barracuda Web Application Firewall Models 660 and above, the integrated XML Firewall enables a strong new layer of defense for data center security teams to deploy SOAP applications across the perimeter. Web services based applications are vulnerable to attacks such as Denial of Service, malicious code injection, and parameter manipulation. Data center security teams need a firewall capable of protecting all layers of protocols and content (HTTP, SOAP and XML) to properly protect web services applications as they deploy them on to the web.

Addressing web services security requirements separately from existing application security implementations would create undesired DMZ complexity and unnecessary administrative burdens. To optimally deploy, operate and secure SOAP based applications, organizations clearly require the integration of web application and web services security into a single comprehensive application controller.

XML Threat Protection

  • Methods-based approach stops the underlying methods used to compromise XML enabled applications, preventing even unknown or “accidental” XML threats
  • Web Services Cloaking masks the true internal URL of mission-critical web services, making them more difficult for hackers to target
  • Automatically validates XML schemas to ensure full compliance to the protocols and specifications governing their use
  • Inspects and validates SOAP envelopes, headers and message content to ensure that all web services are correctly formed
  • Conducts full XML content inspection, looking for policy violations such as oversized messages, unexpected field values and inappropriate external references
  • Ensures that all web services transactions conform to extensive WS-I Basic Profile requirements for security and interoperability
  • Protects against XML Denial of Service (XDoS) threats such as coercive parsing, external entity attacks, jumbo payloads, and recursive elements attacks

Web Services Deployment and Controls

  • Lets security administrators set limits on web services usage without having to learn all the details of XML
  • Gives security managers a single consistent interface for managing web application and web services security
  • Allows application developers to safely extend new web services to partners without compromising perimeter security policies
  • Allows developers to roll out secure web services in hours instead of months
  • Leverages existing access control infrastructure to allow rapid deployment of new web services with no risk
  • Provides detailed, integrated logging and audit information for all web application and web services events
  • Helps IT operations avoid costly unscheduled patching of application servers to cover new exploits
