摘要：A device for automatically controlling access between a local area network anda wide area network is disclosed. The device includes a switch which is positioned betweenthe local area network and the wide area network to disconnect the local area network
from the wide area network. The switch is further arranged to be automatically
controlled based on a system-generated input signal, the signal indicating the expectedneed for access between the local area network and the wide are network the devicebeing adapted to keep the switch disconnected when the input signal indicates that noneed for access between the local area network and the wide area network is expected.Thus, the time during which the local area network is connected to the wide areanetwork, and consequently the time during which the local area network is vulnerable tooutside attacks, can be significantly reduced. A method for automatically controllingaccess between a local area network and a wide area network is also disclosed.
