Creating Web or Secure Web Application Defenses
Configuring the Add New File Extension window
This window allows you to specify additional file extensions on which
to filter. In the File Extension field, type the extension that you want to
add, and then click Add. The file extension is added to the Custom file
extension list. If you select the Custom file extension option, all file
extensions listed in the box will be allowed, denied, or filtered
depending on the action you select.
Configuring the Default filtering rule action
The default filter rule is a catch-all rule designed to occupy the last
position in your rule table. To modify the default action for the default
MIME filtering rule, do the followings:
1. Select the default rule in the table and click Modify. The MIME Default
Action window appears.
2. Select the appropriate action for this rule and then click OK.
Allow—The default rule is initially configured to allow all data that
does not match other filter rules. If you leave the default rule as an
allow rule, you must create filter rules that require virus scanning or
explicitly deny any MIME types that you do not want to allow, and
place them in front of the default allow rule.
Deny—If you prefer the default rule to deny all data that did not
match a filter rule, you must create the appropriate virus scan and
allow rules and place them in front of the default deny rule.
Virus Scan—If you want to perform virus scanning for traffic that
does not match any allow or deny filter rules you create, select this
option. You will then need to create the appropriate allow and
deny rules that will not require scanning.
Configuring the Web/Secure Web Content Control tab
To configure content control properties for a Web/Secure Web
defense, click the Content Control tab. The following window
appears.
