CyberSecurity: DNS Tunnel
DNS is a service that is used on every system with general purpose use of the
internet. It is therefore a convenient target for misuse. The misuse under consideration
here is tunneling. With DNS tunneling, another protocol can be tunneled through DNS.
A DNS tunnel can be used for ‗command and control‘, data exfiltration or tunneling of
any internet protocol (IP) traffic.
