On the Internet, it’s not only “always DNS” – it’s also about securing DNS. DNS faces a wide range of attack vectors, each requiring different defensive strategies. Here comes an overview of DNS security, which gives you all the keywords at a glance.
I was presenting at the annual “Wireshark Developer and User Conference“, the SharkFest’25 EU, talking about “Securing DNS – Attacks and Defences“. It covered all the buzzwords related to DNS security, such as malware using DNS, DNS spoofing, DNS exfiltration & tunnelling, while defending them with the keywords as DNSSEC, DoH/DoT, feeds & blocklists, and so on.
Quite many techniques. ;) Luckily, the whole session was recorded. So if you’re interested, have a look!
