The DNS over HTTPS (DoH) Mess
Summary
This article discusses the complexities and potential issues arising from the implementation of DNS over HTTPS (DoH). It highlights that while DoH aims to improve privacy and security by encrypting DNS queries, misconfigurations or incomplete implementations can lead to network connectivity problems and security gaps.
IFF Assessment
The article discusses how the implementation of DoH, while intended for security, can introduce new complexities and potential security gaps if not properly configured, which poses challenges for defenders.
Defender Context
Defenders need to be aware of the potential security implications and configuration challenges associated with DoH. Improperly implemented DoH can create blind spots for network monitoring and could be exploited by attackers who understand the protocol's nuances.
