METHOD AND DEVICE FOR PROTECTING INFORMATION RESOURCES OF LOCAL AREA NETWORK CONNECTED TO GLOBAL AREA INFORMATION PROCESSING NETWORK FROM UNAUTHORIZED ACCESS OF THE GLOBAL AREA INFORMATION PROCESSING NETWORK USERS TO THE LOCAL AREA NETWORK IN EXCHANGING SIGNALS OF E-MAIL MESSAGES

摘要

network communication engineering. SUBSTANCE: method involves recording e-mail message signal into the local area network server memory and then copying the signal from the local area network server memory into the memory of intermediate signal recorder unit for some given time. The e-mail message signals are removed from the local area network server memory. The e-mail message signal is saved in the global area information network server memory from the intermediate signal recorder unit memory. Global area information network user message signal is transmitted in the like manner. The corresponding device has servers, intermediate signal recorder unit and means for controlling connections, unit for creating and receiving e-mail message signals. EFFECT: enhanced effectiveness of protection. 2 cl, 1 dwg
