Enabling File Blocking and the Default Rule Parent topic

The Default File Blocking rule applies to Anyone and IM Security takes the Cancel file transfer action on files that exceed the specified limit. The Default rule applies to the invitation layer.

Procedure

  2. Select Enable file blocking.
  3. In the File Blocking rule list, set the File size limit for the [Default rule] and specify the file size in MB or KB.
  4. Enable specific rules by changing the Enabled icon from disabled (icon_disabled_rule.jpg) to enabled (icon_enabled_rule.jpg).
  5. To change the order in which IM Security processes the rules:
    1. Select the check box beside a rule name and click Change Priority.
    2. Under the Priority column, type the new priority for the rule in the text box that appears.
    3. Click Save each time you want to change the priority for a rule.
    Note
    Note
    IM Security displays and implements the File Blocking rules in a linear fashion starting from the [Default rule] up to the last rule according to the Priority.
