Abstract
In some examples, a Domain Name System (DNS) server receives, over a network, DNS queries containing domain names, extracts a common domain name shared by the domain names, determines whether a measure of an amount of data relating to the DNS queries containing the common domain name exceeds a threshold, and in response to determining that the measure of the amount of data relating to the DNS queries containing the common domain name exceeds the threshold, trigger a countermeasure action to address a threat associated with the DNS queries.
