Abstract: The disclosed systems and methods can provide a closed-loop system that enables network operators to perform streaming analytics for network monitoring applications at scale. The disclosed systems and methods can allow operators to express network monitoring queries as operations over tuples, and can allow them to partition the queries across both switches and a stream processor, and, through iterative refinement, attempt to extract only the traffic that pertains to the query, thus ensuring that the stream processor can scale to satisfy a large number of queries for traffic at very high rates. According to an example method, network monitoring queries are partitioned between components in a network and iteratively refined based on output of the network monitoring query. The network components can include a data plane component (e.g., a switch) and a stream processor component. The network monitoring queries can be refined based on output from the stream processor component.

Abstract: A system and method for detecting a first network of compromised computers in a second network of computers, comprising: collecting Domain Name System (DNS) data for the second network; examining the collected data relative to DNS data from known comprised and/or uncompromised computers in the second network; and determining the existence of the first network and/or the identity of compromised computers in the second network based on the examination.

Abstract: Collect Domain Name System (DNS) data, the DNS data generated by a DNS server and/or similar device, wherein the DNS data comprises DNS queries, wherein the collected DNS data comprises DNS query rate information. Examine the collected DNS data relative to DNS data from known compromised and/or uncompromised computers. Determine an existence of the collection of compromised networks and/or computers, and/or an identity of compromised networks and/or computers, based on the examination.
