Discussed is a contactor management method and a battery system to perform the method, wherein the battery system includes a contactor connected between a battery pack and an external device; a voltage measurer to measure a first operation voltage supplied to the contactor; and a controller to determine opening or closing of the contactor based on the first operation voltage measured from the voltage measurer, wherein the controller determines the contactor as open in an opened state when the first operation voltage is not supplied to the contactor, determines the contactor as closed in a closed state when the first operation voltage is supplied to the contactor, and counts each openings and closings of the contactor and determines a replacement time of the contactor based on a sum value of the counts exceeding a predetermined reference value.

Contactor management method and battery system providing the same method thereof

A micro controller unit (MCU) includes a flash memory, wherein the flash memory determines a key value of an application when the MCU is powered on, and, when the key value of the application is invalid, the flash memory enters a mode that enables reprogramming of the flash memory.

A memory alignment randomization method of a memory heap exploit is provided, memory alignment of objects inside a heap area is randomly performed to mitigate the exploits of the vulnerability of the software memory heap area The heap exploit is powerfully mitigated by aligning randomly obtained memory addresses instead of aligning memory addresses at multiples of 4 or 8 when the memory alignment for the objects inside the heap area.

Memory alignment randomization method for mitigation of heap exploit

A snoop-based kernel integrity monitoring apparatus and a method thereof are provided. More particularly, provided are a kernel integrity monitoring apparatus which is provided as a hardware device independent of a host system, and snoops traffic occurring in a system bus of the host system and by detecting a write attempt in a kernel immutable region, monitors integrity of the kernel, and a method thereof. According to the apparatus and method, by analyzing traffic of the system bus of the host system, a write attempt in the kernel immutable region is detected. Thus, a transient attack which is difficult for a snapshot method to detect can be detected.

Snoop-based kernel integrity monitoring apparatus and method thereof
