Design and implementation of linked network security system based on virtualization in the separate network environment

Abstract

In this study a Linked Network Security system based on Virtualization (LNSV) is proposed to effectively perform data transmissions in a network separated environment under the aspects of management, operation, and cost. The LNSV proposed in this study represents an open architecture in accessing its system through network connectors for all users in individual networks and can be used as a general purposed system for storing all data to be transmitted. It is possible to prevent the access of unauthorized users because the stored data files include source IP/PORT, destination IP/PORT and Hash Values. Also, it can guarantee the security of communication through transmitting and receiving data using encryption/decryption functions. Thus, the LNSV can provide safe connection services between separated networks. © 2013 Springer Science+Business Media.
