DNS: What It Is, What It Does, and How to Defend It
DNS is part of the foundation of the Internet. It lets humans set up connections and interactions between machines when surfing the web, sending tweets and snaps, paying out money via Venmo and Patreon, online gaming, streaming media, and all other Internet activity seen and unseen. But for all its importance, DNS can be incredibly fragile.
Servers and hosts are still vulnerable to spoofing attacks and misdirections and denial of service. In fact, just recently, a new DNS cache poisoning attack was announced (along with a patch and defensive mitigations). DNS is constantly used by bad guys to carry out attacks, orchestrate C2 (command and control), and exfiltrate data. This talk will give an overview of DNS, DNSSEC, and the new protocols of DOH and DOT that may add security and privacy. Then we will talk about how DNS can be used maliciously and how defenders can protect their networks, their data, and their users.
