Abstract: An apparatus and method for protecting kernel data integrity in an electronic device are provided. The method includes mapping a specified type of data to a read-only memory area, detecting a write attempt to the specified type of data, determining whether a process attempting to write to the specified type of data is permitted according to a specified condition, and allowing the write attempt if the process attempting to write to the specified type of data satisfies the specified condition.
