Security and Architectural Patterns for Securing the Cloud Architecture

摘要

Operating a cloud securely and efficiently entails a great deal of advanceplanning. A data center and redundant internet connection is required at the beginning to connect to cloud. This can constitute the technology portion of an information security and some network devices that safely a nd securely serve the communication. National Institute of Standards and Technology states that the process of uniquely assigning the information resources to an information system will define the security boundary for that system. A massive amount of gear that is racked and cabled following defined patterns is enabled inside this boundary. Need for the infrastructure that is used to manage the cloud and its resources as it operates the cloud. Each component like server, network and storagerequires some degree of configuration . While designing or planning a complex systemit is important to look ahead the process and procedures required for operation of the system. Small cloud systems can be build without much of planning. But any Cloud system substantially bigger size needs significant planning and design. If we fail to plan it leads to higher cost due to inefficiency in design and process. In this paper we study on the architectural components that can be used to build a cloud with security as a priority. This can be achieved by identifying requirements for secured cloud architecture along with key patterns and architectural elements. This paper first discusses on security patterns and an architectural element required and also focuses on several different cloud architectures and secure cloud operation strategies.
