Blockchain technology is attracting a lot of attention among the security community since it provides a way to exchange information among a set of distrusting entities without the use of digital certificates and centralised control. Blockchain provides means for distrusting parties to reach consensus in a distributed way. Although the main application of blockchains are financial systems, their use in the field of networking is currently being explored (e.g., Blockstack or Namecoin). … Read more

A Software-based Approach to Identify Heavy Hitters in DNS Traffic
A Software-based Approach to Identify Heavy Hitters in DNS Traffic
Santiago Ruano Rincón — 25 Oct 2017

This article presents a software-based prototype able to estimate the most queried domain names in a stream of DNS traffic at 12Mpps (wire-rate 10GbE). The goal is to identify domains involved in random qname attacks. This prototype is a proof-of-concept of our research on software and commodity-hardware approaches to analyse high-speed network streams.… Read more
