Configuring Barracuda CloudGen WAF on your Virtual Private Cloud


Installing a web application firewall (WAF) in your virtual private cloud (VPC) protects your applications against sophisticated threats. Possible threats include Structure Query Language (SQL) injection, cross-site scripting (XSS), malware uploads, and application Distributed Denial of Service (DDoS) attacks. Installing a WAF can improve overall application performance while mitigating risks. Most WAFs include built-in application delivery features such as Secure Socket Layer (SSL) offloading, load balancing, and content caching,

To get the most out of the protection that your WAF provides, you should optimize its configuration for your AWS environment. Different environments require different features to be enabled, and not all the default settings are sufficient for all environments. A well-configured WAF helps minimize unnecessary threat alerts, secure your applications against various types of attacks, and cut costs associated with maintenance. It does this by automatically adjusting the configuration of security policies once established.

Barracuda’s CloudGen WAF product comes with standard configurations and rule sets to enable rapid deployment in your environment. This allows you to quickly get up and running and start protecting your applications, even with complex requirements.
