Next Generation Application Delivery Platform

Flexible Deployment: The Barracuda Web Application Firewall offers multiple deployment options for maximum flexibility while ensuring complete security. Built ground up for full reverse proxy deployments, the Barracuda Web Application Firewall insures maximum security and application acceleration in the industry accepted best practice for secure application deployment. In addition to reverse proxy, the appliance can be deployed in one-armed proxy or bridge modes. An inbuilt FIPS 140-2 Level 2 HSM model provides regulatory compliance in the strictest environments.

IPv6/IPv4 Capable: The Barracuda Web Applications Firewall is IPv6 ready, offering easy integration into IPv6 or mixed IPv4/IPv6 environments. This gives organizations the flexibility to use the Barracuda Web Application Firewall as an IPv6 gateway while keeping it internal servers on IPv4 until it is ready for full end-to-end IPv6 networks.

Comprehensive security: The Barracuda Web Application Firewall provides unparalleled application security to help organizations secure critical web assets. The security capabilities of the Barracuda Web Application Firewall are further augmented by an extensive network of more than 150,000 sensors that are deployed worldwide and feed into Barracuda Labs. The sensors provide valuable data to the security research team to build new security definitions and automatically update Barracuda Web Application Firewalls in the field.

Centralized control with Barracuda Control Center: The Barracuda Control Center is the centralized management platform for all Barracuda Networks products. The Barracuda Control Center acts as the centralized policy decision point, while the Barracuda Web Application Firewall acts as the policy enforcement point. The Barracuda Control Center also enables administrators to have an aggregated view of the distributed network via a centralized console. This console can provide aggregated reporting based on data from all of the enforcement endpoints.

Application-Layer Security

Input validation: Lack of proper input validation is one of the prime culprits in Layer 7 security vulnerabilities. The Barracuda Web Application Firewall decrypts all encrypted traffic and normalizes inputs to ensure that all data is inspected and validated against known attack patterns before sending to the backend servers. Protocol Validation allows administrators to enforce protocol versions or verbs for HTTP, HTTPS, FTP or FTPS.

Cloaking: The Barracuda Web Application Firewall cloaking capability strips out all server related information such as server headers and server banners. Denying information about the server infrastructure restricts the attacker’s ability to tune their attacks based on the type of web servers, Operating System, or databases being used.

Session Tampering Protection: Most applications use cookies or hidden, read-only parameters for application session state and other sensitive information. The Barracuda Web Application Firewall can encrypt or sign these tokens to prevent third party impersonation attacks.

Session Riding and Clickjacking Protection: Third party sites can employ malicious JavaScript that exploits the servers trust with the user’s browser. The Barracuda Web Application Firewall blocks such attacks by generating unique tokens or injection anti-UI redressing measures to prevent malicious JavaScript from attacks like Session Riding or Clickjacking.

Anti-virus and malware protection: Web applications that allow files to be uploaded can also utilize the built-in anti-virus and anti-malware scanner to ensure that infected files are not uploaded to the web application.

Layer 7 DDoS Protection: Distributed Denial of Service attacks (DDoS) attacks have moved to the application layer as they provide higher impact compared to network layer DDoS. Due to its complete visibility into application layer constructs, the Barracuda Web Application Firewall can intelligently fingerprint and throttle these attacks and ensure that the protected web applications continue to service genuine users.

Brute Force protection: The Barracuda Web Application Firewall tracks user access to restricted resources and blocks clients if the server does not accept the supplied credentials. Additional rate controlling mechanisms in the Barracuda Web Application Firewall provide additional layer of security against brute force attempts.

XML / Web Services protection: Service Oriented Architectures (SOA) with web services is used to build large, distributed and scalable applications. These applications, along with many Web 2.0 based applications, use XML for transferring data between servers and between clients and servers. The XML Firewall built into the Barracuda Web Application Firewall enforces structure on web services and XML data interchange using WSDL and XML Schema provides protection against XML attacks.

Data Loss Protection: In addition to inbound content inspection, the Barracuda Web Application Firewall also offers outbound content inspection for Data Loss Prevention. The Barracuda Web Application Firewall prevents data leakage by either masking or blocking responses containing sensitive information such as credit card numbers or any other custom data patterns.

Access Control

Authentication: The Barracuda Web Application Firewall integrates with any user database using LDAP or RADIUS to authenticate a user’s credentials before granting access to the secured resources. This allows administrators to add an authentication layer or to offload an existing application authentication policy to the Barracuda Web Application Firewall.

Authorization: Authenticated users can be granted different access privileges by applying access control rules. These privileges can be based on a user’s accounts or on the group to which the user belongs.

Two-factor authentication: Password-based security can be augmented by using client certificates or security tokens. The Barracuda Web Application Firewall integrates with RSA SecurID and client certificates to provide this extended layer of security.

Single Sign On (SSO): For a group of applications that need client authentication before granting access, single sign on is used to provide clients with one seamless authentication system, whereby the client logs in once and their identity is propagated to all applications in the group. The Barracuda Web Application Firewall integrates with CA SiteMinder to enable administrators to build a single sign on portal for all of their web applications.

Scaling the Application Infrastructure

The Barracuda Web Application Firewall provides significant capabilities that enable organizations to scale their application deployment infrastructure.

Load balancing: The built-in load balancing module distributes incoming traffic across the available servers using one of many available algorithms, such as Weighted Round Robin or Least Connections. Availability of multiple servers is monitored with the help of an integrated application monitoring module. Traffic can be distributed at Layer 4 or at Layer 7.

Layer 7 content routing: The Barracuda Web Application Firewall provides enormous flexibility while deploying large applications in which each application module can be deployed on multiple servers. Requested content such as the URL of the module, HTTP Headers and parameters, is used to route content to the correct set of servers.

SSL offloading: Web servers hosting HTTPS websites require a significant amount of processing power in handling SSL encryption / decryption. The Barracuda Web Application Firewall provides SSL offloading capabilities,
thereby freeing up the processing power of the servers and making them more efficient.

Instant SSL: Using the Instant SSL capability of the Barracuda Web Application Firewall, deployment teams can convert their HTTP based applications to HTTPS without having to touch the application code.

Rate control: The Barracuda Web Application Firewall can control the number of application sessions being created and/or how many times a client can access a given resource. These measures, in conjunction
with other rate control techniques such as client queuing, protect web applications from application-level denial of service (DoS) attacks.

Accelerating application delivery

Caching: The Barracuda Web Application Firewall speeds up application response time by caching static content and using it to respond to repeated requests for the same content. Caching rules can be tuned based on URL space, file size or file type.

Compression: The integrated compression engine in the Barracuda Web Application Firewall compresses data as it is sent out to the client. This capability is extremely useful in low bandwidth situations and makes application delivery faster.

Protocol tuning: The Barracuda Web Application firewall employs multiple techniques such as connection-pooling and TCP multiplexing to optimize protocol performance. Connection pooling techniques enable Barracuda Web Application Firewall to cut down the overhead associated with creating and terminating connections, thereby cutting the time it takes to respond to client requests.
