Title:
SECURITY GATEWAY COMMUNICATION
Document Type and Number:
WIPO Patent Application WO/2013/013189
Kind Code:
A3
Abstract:
A gateway device and methods performed therein to prevent unauthorized client devices from connecting to the host network of the gateway device is described. The gateway device does not respond right away to an individual client message sent to the gateway device. Instead, the gateway device only responds to a predetermined sequence of the client messages, which is only known to the gateway device and authorized client devices. Because the gateway device will not respond to random client messages and the likelihood that an unauthorized client device can correctly guess the predetermined sequence of the client messages is low, the risk of a malicious party being able to hack into the host network, for example, by using port scanning techniques, can be mitigated.
