FIELD: information technology.
SUBSTANCE: invention relates to protection of data from unauthorised transmission, and specifically to detection device for communication between communication devices in a network with which communication is allowed. For this purpose, when first device is detected in first network, device is polled in second network on whether detected first device is a device having actual association to said device. If after polling, it is determined that detected first device is a device having actual association to said device, data are obtained from detected first device. On other hand, if it is determined that detected first device is not a device having actual association to said device, data are not obtained from detected first device.
EFFECT: technical result is faster detection of related devices and prevention of data transfer of unassociated devices.
