METHOD FOR PROTECTION OF LOCAL COMPUTING-NETWORK AT TRANSMISSION OF ELECTRONIC MAIL MESSAGES BY MEANS OF GLOBAL INFORMATION NETWORK Russian patent published in 2008 - IPC H04L12/54 

FIELD: electric communication, applicable in local computing networks for improvement of their safety at transmission of electronic mail messages, via the global information network.

SUBSTANCE: the method consists in forming of electronic mail messages in the local computing networks, where they are memorized. Then these messages are read ant and memorized in the intermediate recording means memory. The mentioned messages are removed from the server of the local computing network, read server of the local computing network, read out of the intermediate recording means memory and transmitted to the server of the global information network. In addition, a set of identifiers of the controlled message senders, fields of their head-lines, their admissible values and the rule of selection are preset. At a coincidence of the identifiers of the electronic mail messages with the preset indicators the fields of the controlled messages are modified by way of their replacement. The mentioned actions complicate the probability of destructive actions on the local computing networks, which enhances their safety of operation.

EFFECT: enhanced safety of the local computing network due to masking of its characteristics at transmission of electronic mail messages by means of the global information network.
