Configuring the Default filter rule action
Creating Citrix Application Defenses
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 messages
that do 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 messages
that do not match other allow or deny filter rules, select this
option. You will then need to create the appropriate allow and
deny rules that will not require scanning.
To configure Citrix Application Defenses, in the Admin Console select
Policy Configuration -> Application Defenses -> Defenses -> Citrix. The
following window appears. (Figure 6-13 displays only the bottom
portion of the windows.)
