DNS security doesn’t have to be confusing! In this session, we’ll break down DNSSEC, DoT, DoH, and DoQ in simple terms—what they do, how they’re different, and why you need to know when and where to use each one. We’ll take a hands-on look with Wireshark to see how these protocols actually behave at the packet level. By the end, you'll have a solid grasp of how to secure your DNS traffic, what Protective DNS really does, and how to pick the right tool for the job.
Beginners welcome. DNS newbies too.
Like you, Chris likes digging into packet captures to figure out how things work. When he is not teaching people the art of packet analysis in live courses, YouTube videos, or at conference seminars, you can find him in the packet trenches with clients from all over the world. Chris has been attending and speaking at Sharkfest since 2011 and enjoys learning new things right alongside attendees of all experience levels.
