What is DNS tunneling?
DNS tunneling involves abuse of the underlying DNS protocol. Instead of using DNS requests and replies to perform legitimate IP address lookups, malware uses it to implement a command and control channel with its handler. DNS’s flexibility makes it a good choice for data exfiltration; however, it has its limits.

Is DNS secure?
DNS is widely trusted by organizations, and DNS traffic is typically allowed to pass freely through network firewalls. However, it is commonly attacked and abused by cybercriminals. As a result, the security of DNS is a critical component of network security.
What is TCP over DNS?

This is similiar to the defunct NSTX dns tunelling software. The purpose of this software to is succeed where NSTX failed.
This tunnel can be used to exfiltrate data or for other malicious purposes. Because there is no direct connection between the attacker and victim, it is more difficult to trace the attacker’s computer.
How do I protect DNS tunneling?
To avoid the possession of data, a tool must be installed that blacklists the destinations which are to extract data. This activity must be done on a regular basis. A DNS firewall should be configured and designed such that it quickly identifies any intrusion. A firewall serves as a pathway for exfiltration.
How do DNS work?
The Internet’s DNS system works much like a phone book by managing the mapping between names and numbers. DNS servers translate requests for names into IP addresses, controlling which server an end user will reach when they type a domain name into their web browser. These requests are called queries.
How do I investigate DNS tunneling?
DNS tunnels can be detected by analyzing a single DNS payload or by traffic analysis such as analyzing count and frequency of requests. Payload analysis is used to detect malicious activity based on a single request.
What is DNS exfiltration?
DNS data exfiltration is a way to exchange data between two computers without any direct connection. The data is exchanged through DNS protocol on intermediate DNS servers. During the exfiltration phase, the client makes a DNS resolution request to an external DNS server address.

What is DNS Tunnelling and how can it be detected?
DNS tunneling is a difficult-to-detect attack that routes DNS requests to the attacker’s server, providing attackers a covert command and control channel, and data exfiltration path. DNS is like a phonebook for the internet, helping to translate between IP addresses and domain names.
How does Zscaler DNS work?
Zscaler performs DNS resolution for the proxied traffic. However, for the traffic that is exempted based on the App Profile’s PAC file or Forwarding Profile’s PAC file, the DNS resolution is performed locally at the client side. A DNS resolution is first performed locally at the client side for all the traffic.
