Enabling Performance Optimization
The Performance Optimization option allows you to disable some relatively less severe signatures that
significantly affect the performance of certain Web applications. These signatures are identified by the Dell
SonicWALL signature team and the list is pushed out to SMA/SRA appliances. When you select Enable
Performance Optimization, these signatures are disabled for Web Application Firewall.
The Web Application Firewall > Signatures page indicates the disabled signatures by displaying them in gray, as
shown in Figure 43.

Configuring Signature Based Custom Handling and Exclusions
You can disable inspection for a signature in traffic to an individual host, or for all hosts. You can also change
the handling of detected threats for an individual host or for all hosts. If the signature group to which the
signature belongs is set globally to Detect All, you can raise the level of protection to Prevent for the configured
hosts. If no hosts are configured, the action is applied to the signature itself and acts as a global setting for all
hosts. This change blocks access to a host when the attack signature is detected. Similarly, you can lower the
level of protection to Detect if the associated signature group is globally set to Prevent All.
NOTE: For signature based customization to take effect, the signature group of the modified signature
must be globally enabled for either prevention or detection on the Web Application Firewall > Settings
page.
To configure one or more hosts with an exclusion from inspection for a signature, or to
configure custom handling when Web Application Firewall detects a specific signature for one
or more hosts, complete the following steps:
