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
SRA appliances. When you select the Enable Performance Optimization check box, 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 38
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 will block
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.
