Traceable Enterprise Information Security Architecture Methodology

Abstract

With the introduction of networking into telemetry applications, these systems have become increasingly complex. This imposes significant strain on information security for architecture designs. It has been recognized that an organized or structured approach to developing security architectures is needed. Several enterprise architecture frameworks are available today that address system complexity. However they fall short of addressing security at a high enough level in the enterprise and address security too late in the design process. In this paper a methodology is proposed that bridges the gap between security requirements and architecture design development at the enterprise level. This approach is consistent with and traceable to the original needs of the customer. This paper introduces a systems engineering approach to develop an enterprise level methodology, and presents a worked example of this approach for the integrated Network Enhanced Telemetry system.
