DNS Filtering and Botnet Protection 5.4 (Video)


In this video, you will learn how to protect your network from Botnet C&C attacks using the FortiGuard Botnet C&C database feature, and block access to social networking sites using the Static Domain Filter. You will create a new DNS Filter security profile called Botnet&Facebook, block access to all known C&C addresses, and block access to the Social Networking FortiGuard category.

The recipe for this video is available here.

    Hi Luca,

    DNS filtering was made available in flow-mode in FortiOS 5.4.2. This video was recorded using an earlier version of the firmware.

    Is there a way, instead of it returning NXDOMAIN, to have it return an IP address of your choosing? perhaps to a “page blocked” site. That’s much more helpful to the user (and the help desk). Obviously the page blocked site would only help for web requests, but that’s what most people would be doing when thy get run up against a denied name anyway.
