SRA Overview | 63
Deploying Web Application Firewall at the SRA appliance lets network administrators use
application offloading even when it exposes Web applications needing security to internal and
remote users. Application offloading avoids URL rewriting, which improves the proxy
performance and functionality.
There are several benefits of integrating Web Application Firewall with Dell SonicWALL SRA
appliances. Firstly, identity-based policy controls are core to Web Application Firewall and this
is easily achievable using SSL VPN technology. Secondly, there are lower latencies due to the
existing hardware-based SSL offloading. Most importantly, SRA appliances run Web
applications and must be protected from such attacks.
As small businesses adopt hosted services to facilitate supplier collaboration, inventory
management, online sales, and customer account management, they face the same strict
compliance requirements as large enterprises. Web Application Firewall on a Dell SonicWALL
SRA appliance provides a convenient, cost-effective solution.
Web Application Firewall is easy to configure in the Dell SonicWALL SRA management
interface. The administrator can configure Web Application Firewall settings globally, by attack
priority, and on a per-signature basis. Once custom configuration settings or exclusions are in
place, you can disable Web Application Firewall without losing the configuration, allowing you
to perform maintenance or testing and then easily re-enable it.
How Does Web Application Firewall Work?
To use the Web Application Firewall feature, the administrator must first license the software or
start a free trial. Web Application Firewall must then be enabled on the Web Application Firewall
> Settings page of the Dell SonicWALL SRA management interface.Web Application Firewall
can be configured to log or block detected attacks arriving from the Internet.
