Abstract:
1. A method for detecting a computer-related attack affecting packets transmitted from a source node to a destination network, the source node and the destination network separated by an original end to end path, the destination network being associated with a prefix, the method comprising: determining a current end to end path from the source node to the destination network; determining a reference node end to end path from the source node to a reference node, the reference node located along the original end to end path and associated with a prefix different than the prefix associated with the destination network; converting the current end to end path to a current autonomous system path and converting the reference node end to end path to a reference autonomous system path; comparing the current autonomous system path to the reference autonomous system path; and detecting a computer-related attack, based on the comparison of the current autonomous system path to the reference autonomous system path.
