Abstract content

DNS stream analysis is an appropriate environment to work with real time analytics due to the extremely large amount of queries that needs to be processed per second.

There are some tools used to analyze DNS traffic, such as DSC, DSCng or Bumblebee, but they focus in statistical analysis, mainly providing visualization of data aggregations. We will show our system design for a filtering and grouping tool based on the Apache Storm streaming framework, in order to analyze a live stream of DNS packets received by a cloud of DNS servers, and some basics results from testing our prototype analyzing the traces recorded at DITL.

By developing this Storm based tool we also aim to help DNS Admins to monitor some general statistics of their servers as the other tools do, such as the historical percentages of query types, query volume or alternative metrics like current state of load balancing between servers.

Another goal we have is to analyze the historical data of the specific DNS traffic to determine what is the normal behavior of the statistics mentioned above.
