The purpose of this work is to create and analyze the information security models of large corporations. It’s difficult and hard to deploy efficiently safe systems due to complex network environment and enterprise computer systems. It’s important to analyze security system parameters before design process. The enterprise information security system modeling helps us to solve these problems. In this work I designed information security models with complex information security elements and safe data transferring between remote locations. These models will help designers to compare different systems and to find the most secure and effective. This thesis generalizes the information security modeling process and describes the factors influencing it.
