Abstract
A blacklist generating device acquires a malicious communication log and a normal communication log. A malicious communication profile extracting function calculates statistics on communication patterns included in the malicious communication log and outputs a communication pattern satisfying a certain condition to a potential blacklist. A normal communication profile extracting function calculates statistics on communication patterns included in the normal communication log and outputs a communication pattern satisfying a certain condition to a whitelist. A blacklist creating function searches the potential blacklist for a value with the value on the whitelist, excludes a coincident communication pattern from the potential blacklist, and creates a blacklist.
