In an example implementation, the DNS may implement a method that includes monitoring DNS queries received from a computing device at the DNS. The DNS identifies if a fully qualified domain name (FQDN) associated with the DNS query is not present in a cache of the DNS and DNS responses received by the computing device in response to the DNS queries whose FQDN is not present in the cache. An exfiltration, an infiltration or a tunneling event is detected based on a summation of size of the DNS queries, DNS responses or both. Accordingly, further DNS queries from the computing device may be blocked."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and system for detecting and blocking data transfer using DNS protocol","description":"Method(s) and a domain name server (DNS) for detecting and blocking DNS query raised by a computing device are described.
