Video: How DNSSEC Works

This silent video created by Shinkuro, Inc., provides a good visualization of how DNS works normally, how an attacker can hijack DNS queries, and how DNSSEC can protect the integrity of DNS information to ensure that the correct information is received.

You can also view the video directly on YouTube.

There is also a second version of the video that does not include the text narration on the right side of the screen. You may find that useful if, for instance, you are showing the demonstration and explaining what is happening.

This video was produced by Shinkuro, Inc., in 2006 and the original source can be found at:

We have uploaded it to our YouTube channel with the express consent of Shinkuro, Inc. They informed us that the work was created under a U.S. government contract and the resulting video is free for all to use and share.
