Most people think DNSSEC means DNS security. Well... not really in the full sense. It is designed to protect from cache poisoning, but does not encrypt DNS the way many think it does.
We go under the hood with a live Wireshark packet capture to see how DNSSEC behaves on the wire. You’ll see what it protects, what it doesn’t, and why the word “secure” can be misleading if you take it at face value.
What you’ll learn:
How DNSSEC adds validation to DNS responses
What a signed DNS response looks like in Wireshark
Where DNSSEC doesn’t provide security
Download the pcap and follow along.
