摘要
The present invention relates to an apparatus for monitoring a software procedure change operation based on a pattern using a control flow graph (CFG), to detect illegal action and abnormal operation with respect to software, and a method thereof. According to one embodiment of the present invention, the apparatus for monitoring a software procedure change operation based on a pattern using a CFG comprises: a logical module flow selection unit for discriminating each module in a CFG for a source code of software in accordance with order relation; a CFG pattern extraction unit for generating and extracting a sequence pattern, a depth pattern, and a range-position pattern through abstraction in accordance with a purging probability of a purging test with respect to each discriminated module and a transition probability distribution of each module; and a dynamic tracking unit using the sequence pattern, the depth pattern, and the range-position pattern to measure or detect an abnormality degree in accordance with procedure change of the source code of the software.;COPYRIGHT KIPO 2019
