The firewall uses file blocking profiles to block specified file types over specified applications and in the specified session flow direction (inbound/outbound/both). You can set the profile to alert or block on upload and/or download and you can specify which applications will be subject to the file blocking profile. You can also configure custom block pages that will appear when a user attempts to download the specified file type. This allows the user to take a moment to consider whether or not they want to download a file. Configure a file blocking profile with the following actions:
Alert - When the specified file type is detected, a log is generated in the data filtering log.
Block - When the specified file type is detected, the file is blocked and a customizable block page is presented to the user. A log is also generated in the data filtering log.
Continue - When the specified file type is detected, a customizable response page is presented to the user. The user can click through the page to download the file. A log is also generated in the data filtering log. Because this type of forwarding action requires user interaction, it is only applicable for web traffic.
