Adding a URL filtering policy is a two-step procedure. First, you create
an account and then you assign URL filtering rules to the new account.
Editing a URL filtering policy requires clicking on the policy name,
then clicking the Rule tab.
Allow—Connection
to the target server is allowed and users can access the Web site.
Block—Connection
to the target server is not established and users are not allowed to access
the Web site. A log entry is also created for this event.
Block
w/Override—Connection to target service is not established unless
the user can type a specific password to override the category blocking.
Note:
Applying the "block with override" action to categories in a
policy requires administrators to enter the password used for overriding
when creating the policy. Enter this password in the "Password Override
Settings" section below the list of categories.
Monitor—Connection
to the target server is allowed and users can access the Web site. A log
entry is also created for this event.
Time
Limit—Connection to the target server which accesses selected categories
of URLs is allowed for the period of time configured by the administrator.
Notes:
1. Selecting the "Time Limit" action for categories requires
administrators to enter a value in "Time quota" text box in
the Time Limit Settings section under the list of categories.
2. The default quota unit is five minutes. Trend Micro recommends that
administrators set the "Time quota" value to a multiple of five.
Otherwise, IWSVA ignores the remainder less than five. For example, if
the value is set to 4 minutes, IWSVA interprets that as 0 minutes. If
the value is set to 9 minutes, system interprets that as 5 minutes.
Warn—Connection
to the target server is allowed but a notification displays, warning users
that the URL about to be accessed belongs to a category that violates
company policy. Users have the option of continuing to the page or going
back to the previous page.
