Abstract
Methods and systems are provided for preventing unauthorized communication with an end device on a network, the system comprising an external device and a communication device. The communication device includes an interface configured to be communicatively coupled to the external device, and being configured to receive access attempts from the external device, at least one of which being structured according to a respective communication protocol and being received from a respective communication zone, determine a group of used communication protocols, the group of used communication protocols including protocols according to which the access attempts are structured and being determined based on the respective communication zones of the access attempts, receive, from a first external device, an access attempt structured according to a protocol not in the group of communication protocols, and deny, responsive to determining that the protocol is not in the group of used communication protocols, the access attempt.
