Abstract
The present application describes a system and method for passively collecting DNS traffic data as that data is passed between a recursive DNS resolver and an authoritative DNS server. The information contained in the collected DNS traffic data is used to generate a virtual authoritative DNS server, or a zone associated with the authoritative DNS server, when it is determined that the authoritative DNS server has been compromised.
