Abstract: Provided are an apparatus for supporting power-saving for a wireless repeater and a method thereof. The apparatus for supporting power-saving for the wireless repeater includes: an information receiving unit that receives information regarding adjacent wireless repeaters from each of peripheral wireless repeaters; a group forming unit that forms groups of wireless repeaters based on the information regarding adjacent wireless repeaters received by the information receiving unit; a leader setting unit that sets a leader in the group of wireless repeaters formed by the group forming unit; and a mode providing unit that provides a power-saving mode to the remaining wireless repeaters except for the wireless repeater as the leader by the leader setting unit among the groups of wireless repeaters formed by the group forming unit.

Abstract: Provided is a control method of an access point controller (APC), the method including: (a) if occurrence of a predetermined security vulnerability checking event on particular terminal equipment is sensed, controlling the plurality of APs so that port scanning is capable of being performed on the particular terminal equipment; and (b) determining that security vulnerability has occurred in the particular terminal equipment in at least one of a case where the predetermined port is opened, a case where the predetermined port is closed, and a case where the number of opened ports exceeds a predetermined number, as a result of performing port scanning on the particular terminal equipment.
