Abstract: An electronic apparatus is disclosed. The electronic apparatus includes: a communication interface comprising communication circuitry, and a processor configured to: identify strength of a signal received from an external device through the communication interface, based on the strength of the identified signal being greater than or equal to a threshold value, unlock authorization restriction on the electronic apparatus, wherein the processor is further configured to: based on the strength of the identified signal being less than the threshold value, maintain the authorization restriction, and based on authentication of the electronic apparatus being completed after the signal is received, adjust the threshold value based on strength of at least one signal received from the external device before the signal is received.

Abstract: An electronic device is disclosed. An electronic device comprises: a first memory in which an operating system and an application program executed on the operating system are stored; a second memory; a processor for loading at least some codes among codes corresponding to an application program from the first memory to the second memory, and when access information of the codes loaded in the second memory is received from a kernel of an operating system, accessing an area in which the loaded codes are stored, on the basis of the received information and executing the application program; and a snoop for monitoring access to an area in which a preset code, the access of which has been limited, from among codes loaded in the second memory is stored.
