Abstract: Disclosed herein is a method for securing an indirect function call according to an embodiment of the present invention. The method may include searching for an instruction that indirectly calls a function in intermediate representation code, calculating the number of functions that have to be allowed to be indirectly called based on the found instruction, identifying the address of a function loaded at the N-th lowest address arbitrarily set in advance, among the functions, the number of which is calculated, identifying indexes for selecting callee functions to be indirectly called based on the found instruction, determining whether to allow the function to be called using the identified indexes, and determining, when the function is allowed to be called, whether to allow the function to be called using the address of a callee function, the memory address of which is N-th lowest, among the callee functions.

Abstract: Disclosed herein are a method for calculating a risk for an industrial control system and an apparatus for the same. The method includes collecting at least one keyword based on published vulnerabilities in a target industrial control system and generating an attack vector corresponding to the at least one keyword; collecting operating environment characteristics corresponding to the operating environment that is currently being used in the target industrial control system; calculating a targeted risk for the attack vector in consideration of a vulnerability characteristic matching the at least one keyword, among the operating environment characteristics, and a weight applied to the vulnerability characteristic; and providing the targeted risk to the operator module of the target industrial control system.
