Traditionally, DNS has had a last mile security problem: Communications from a local DNS server to a client are almost always unencrypted, and hence vulnerable to spoofing, hijacking and more. DNS privacy standards have emerged to help encrypt those communications.

Join SANS and Infoblox as we explore the two leading DNS privacy standardsDNS over TLS (DoT) and DNS over HTTPS (DoH). Attend and learn:

  • The pros and cons of each protocol
  • Which option makes the most sense for your level of security risk and why
  • Who benefits from your DNS data
  • Simple ways to secure your network and prevent misuse of your DNS

Who Should Attend: Networkers and security practitioners that wish to make more informed choices for protecting DNS pathways from malicious use.
