Media Access Control Address based method for securing access to a local area

摘要

A method for local area network (LAN) security includes monitoring connections between ports (P2, P4, P5) of a central device (12) and a plurality peripheral devices (14a, 14b, 14c) which are respectively cable-connected to the ports (P2, P4, P5), and disabling one of the ports (P2, P4, P5) after detecting a corresponding peripheral device (14a, 14b, 14c) is disconnected from the port (P2, P4, P5).
