Barracuda Web Application Firewall

About the Device

The Barracuda Web Application Firewall blocks an ever-expanding list of sophisticated web-based intrusions and attacks that target applications hosted on web servers and in the cloud. The Barracuda Web Application Firewall scans all inbound web traffic to block attacks and inspects the HTTP responses from the configured back-end servers for Data Loss Prevention (DLP). The integrated access control engine enables administrators to create granular access control policies for Authentication, Authorization & Accounting (AAA) without requiring application changes.

Collection Method

Port Requirements

To facilitate secure communication and align with our best practice, we strongly encourage the use of Transport Layer Security (TLS) between your security devices and our Adaptive MxDR platform for event forwarding.

While we understand that TLS support may not be available on all devices, if your devices do support TLS communication, we recommend utilizing port 6514 for seamless integration.

In some cases, the upgraded version of the device might incorporate TLS support without prior notice. If you come across such a scenario or for further assistance in configuring TLS, we kindly ask you to reach out to your dedicated Adaptive MxDR Service Delivery Lead.
