Claim Text:
1. A method of placing prefix hijacking detection modules in a communication network, the method comprising: determining, by a computing device and by utilizing instructions from memory that are executed by a processor, a first subset of network locations of a plurality of network locations that are subject to prefix hijacking events, wherein the first subset of network locations is contained within a first autonomous system; selecting, by the computing device, a first network location of the plurality of network locations for placing a first hijacking detection module that detects prefix hijacking events directed against the first subset of network locations, wherein selecting the first network location comprises determining a plurality of candidate locations based on the plurality of network locations and determining a plurality of detection coverage ratios corresponding to the plurality of candidate locations, and wherein the first network location is contained within a second autonomous system associated with the first autonomous system; and wherein detecting the prefix hijacking events comprises: wherein determining the plurality of detection coverage ratios comprises:
