<jats:p>The paper proposes effective method of computer network protection from data exfiltration by the system of domain names. Data exfiltration by Domain Name System (DNS) is an approach to conceal the transfer of confidential data to remote adversary using data encapsulation into the requesting domain name. The DNS requests that transfer stolen information from a host infected by malicious software to an external host controlled by a malefactor are considered. The paper proposes a method of detecting such DNS requests based on text classification of domain names by convolutional neural network. The efficiency of the method is based on assumption that domain ...
