DNS is a distributed, fault tolerant system that avoids a single point of failure. As such it is an
integral part of the internet as we use it today and hence deemed a safe protocol which is let …

In recent times, DNS tunneling techniques have been used for malicious purposes, however
network security mechanisms struggle to detect them. Network forensic analysis has been …

This paper presents an advanced analytic capable of detecting general DNS tunneling
behavior with high precision and recall. It explores the application of supervised machine …

For many networks to function properly, DNS is the main protocol. Security policies typically
permit DNS traffic and therefore attackers use DNS traffic for malicious purposes. This …

DNS tunneling techniques are often used for malicious purposes but network security
mechanisms have struggled to detect these. Network forensic analysis has thus been used …

DNS tunneling techniques are often used for malicious purposes. Network security
mechanisms have struggled to detect DNS tunneling. Network forensic analysis has been …

As we live in an era where privacy over the Internet has become rudimentary, protocols like
DNS over HTTPS (DoH) and DNS over TLS (DoT), which promote encryption, have become …

DNS (Domain Name System) tunnels almost obscure the true network activities of users,
which makes it challenging for the gateway or censorship equipment to identify malicious or …

DNS tunneling is a typical attack adopted by cyber-criminals to compromise victims' devices,
steal sensitive data, or perform fraudulent actions against third parties without their …

In this paper, we propose the concept of” entropy of a flow” to augment flow statistical
features for identifying malicious behaviours in DNS tunnels, specifically DNS over HTTPS …
