The present invention relates to a method and an apparatus for detecting anomalies of a DNS traffic in a network comprising analysing, through a network analyser connected to said network, each data packets exchanged in the network, isolating, through the network analyser, from each of the analysed data packets the related DNS packet, evaluating, through a computerized data processing unit, each of the DNS packets generating a DNS packet status, signaling, through the computerized data processing unit, an anomaly of the DNS traffic when the DNS packet status defines a critical state, wherein the evaluating further comprises assessing, through the computerized data processing unit, each of the DNS packet by a plurality of evaluating algorithms generating a DNS packet classification for each of the evaluating algorithms, aggregating, through the computerized data processing unit, the DNS packet classifications generating the DNS packet status, and wherein the critical state is identified when the DNS packet status is comprised in a critical state database stored in a storage medium.

Method and apparatus for detecting anomalies of a DNS traffic

A monitoring network is formed by a terrestrial network and a satellite network. The terrestrial network has a plurality of sensor nodes which send a data packets. The data packets are forwarded through sink nodes toward a satellite and a monitoring station in the satellite network. The monitoring station performs a dynamic selection process for dynamically associating each sensor node to at least one selected sink node among the plurality of sink nodes, thereby the data packets sent by the sensor nodes are transmitted to the satellite through only the selected sink node.
