What is the stack or layers of Enterprise Architecture? enterprise architecture. TOGAF provides a method for you to "architect" the systems in your enterprise. Having a single source of reference is essential to avoiding waste and duplication in large, complex organizations. By using SABSA, COBIT and TOGAF together, a security architecture can be defined that is aligned with business needs and addresses all the stakeholder requirements. The content will be contained within deliverables, which may be represented as catalogs, matrices and/or diagrams. The development of TOGAF Version 1 in 1995 was based on the Technical Architecture Framework for Information Management (TAFIM) developed by the US Department of Defense. Enterprise architecture has become an important tool to utilize the benefits of the hardware, cloud, and for ensuring maximum security of data over various platforms. TOGAF is a tool for assisting in the acceptance, production, use, and maintenance of enterprise architectures. The first phase measures the current maturity of required controls in the environment using the Capability Maturity Model Integration (CMMI) model. The earliest rudiments of the step-wise planning methodology currently advocated by TOGAF and other EA frameworks can be traced back to the article of Marshall K. Evans and Lou R. Hague titled "Master Plan for Information Systems" published in 1962 in Harvard Business Review.

It is based on an iterative process model supported by best practices and a re- usable set of existing architectural assets. This type of structure seems fairly consistent across the different frameworks available today. As an example, when developing computer network architecture, a top-down approach from contextual to component layers can be defined using those principles and processes (figure 4). Published: 2017-12-04 Layering is a core technique in enterprise architecture. This section describes a simple and practical example of the steps that can be taken to define a security architecture for an enterprise. The TOGAF framework goes on to describe the ‘contents’ within each in terms of ‘content metadata’, with relationships between all the pieces and parts. Regardless of the methodology or framework used, enterprise security architecture in any enterprise must be defined based on the available risk to that enterprise. § The Enterprise Continuum is a model for structuring a ‘virtual repository’ of architectural assets such as patterns, models, & architecture descriptions. Has been an IT security consultant since 1999. 2.6 Enterprise Continuum.

It is the most prominent and reliable Enterprise Architecture standard, ensuring consistent standards, methods, and communication among Enterprise Architecture professionals. The TOGAF standard is a globally used architectural framework and standard that enables organizations to design, evaluate and build the right IT architectures. COBIT 5, from ISACA, is “a comprehensive framework that assists enterprises in achieving their objectives for the governance and management of enterprise IT.”1 This framework includes tool sets and processes that bridge the gap between technical issues, business risk and process requirements.
