DNS Security III | DNS Over TLS | Palo Alto Firewall Training

Following on from the previous video on DOH (DNS Over HTTPS) this video looks at how we deal with DOT (DNS over TLS), using QUAD9 DNS service to demonstrate not only the configuration but the difference in how the traffic is blocked and dealt with when traffic is decrypted to when it is not decrypted. Although I used Stubby client on this video I must say that I did not have any particular security concerns when installing it, always make sure that you are happy installing any software in your own environments. #paloaltonetworks #paloaltotraining #paloaltotraining #cybersecurity #dnssecurity #encrypteddns
