Set Up File Blocking on Cloud NGFW for AWS
File Blocking allows you to identify specific file types that you want to block or monitor. For
most traffic (including traffic on your internal network), block files that are
known to carry threats or that have no real use case for upload/download. These
include batch files, DLLs, Java class files, help files, Windows shortcuts (.lnk),
and BitTorrent files.
Cloud NGFW can take
the following actions on files moving through your network.
- 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 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.
In
addition, you can allow or block file types based on the direction
they are going—Download, Upload, or Upload and Download.
