Method and apparatus for modeling computer program behaviour for behavioural detection of malicious program

摘要

A method and apparatus for modeling a behavior of a computer program that is executed in a computer system is described. The method and apparatus for modeling a behavior of a computer program may be used to detect a malicious program based on the behavior of the computer program. A method includes collecting system use information about resources of the computer system the computer program uses; extracting a behavior signature of the computer program from the collected system use information; and encoding the extracted behavior signature to generate a behavior vector. As a result, behaviors of a particular computer program may be modeled to enable a malicious program detection program and to determine whether the computer program is either normal or malicious.
