The first phase measures the current maturity of required controls in the environment using the Capability Maturity Model Integration (CMMI) model. EA applies architecture principles and practices to guide organizations through the business, information, process, and technology changes necessary to execute their … 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. 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. By using a combination of the SABSA frameworks and COBIT principles, enablers and processes, a top-down architecture can be defined for every category in figure 2. SABSA is a business-driven security framework for enterprises that is based on risk and opportunities associated with it. Enterprise, Business and IT Architects at all levels who construct and govern architecture building blocks (ABBs) to enable the creation of effective solution building blocks. Scott Bernard visualizesEA as meta-discipline that covers entire organization, “EA is, therefore, THE architecture of the enterprise and should cover all elements and aspects. In order to have a comprehensive understanding of TOGAF, including process, content, guidelines, roles, structure, learn the seven basic parts of the standard. Security Architecture: A discrete layer? TOGAF provides a method for you to "architect" the systems in your enterprise. Likewise our COBIT® certificates show your understanding and ability to implement the leading global framework for enterprise governance of information and technology (EGIT). TOGAF provides the methods and tools for assisting in the acceptance, production, use, and maintenance of an enterprise architecture. Traditionally, security architecture consists of some preventive, detective and corrective controls that are implemented to protect the enterprise infrastructure and applications. TOGAF is a management framework that features and promotes the role of architects. TOGAF development traces back to 1995 and its current version 9.1 embodies all improvements implemented during this time. Within TOGAF, the structure is defined initially as ‘architecture types’ – Business, Application, Data and Technology. This type of structure seems fairly consistent across the different frameworks available today. The life cycle of the security program can be managed using the TOGAF framework. Figure 1 shows the six layers of this framework. The TOGAF framework goes on to describe the ‘contents’ within each in terms of ‘content metadata’, with relationships between all the pieces and parts. COBIT principles and enablers provide best practices and guidance on business alignment, maximum d… Get in the know about all things information systems and cybersecurity. This maturity can be identified for a range of controls. Ghaznavi-Zadeh is an IT security mentor and trainer and is author of several books about enterprise security architecture and ethical hacking and penetration, which can be found on Google Play or in the Amazon store. After the program is developed and controls are being implemented, the second phase of maturity management begins. It also provides examples of various viewpoints and views. Figure 5. At the business layer, TOGAF recommends the use of modelling techniques to convey the interactions between people and information participating in the conduct of services and processes. The CMMI model is useful for providing a level of visibility for management and the architecture board, and for reporting the maturity of the architecture over time.

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). Enterprise architecture is unique to every organization, however, there are some common elements. New emerging technologies and possibilities, e.g., the Internet of Things, change a lot about how companies operate, what their focus is and their goals. ISACA is, and will continue to be, ready to serve you. The COBIT Process Assessment Model (PAM) provides a complete view of requirement processes and controls for enterprise-grade security architecture. We serve over 145,000 members and enterprises in over 188 countries and awarded over 200,000 globally recognized certifications. Within TOGAF, the structure is defined initially as ‘architecture types’ – Business, Application, Data and Technology. It was released as a reference model for enterprise architecture, offering insight into DoD’s own technical infrastructure, including how it’s structured, maintained and configured to align with specific requirements. In the Enterprise Continuum it describes the concept of a virtual architecture repository containing artifacts and reference models. § The Enterprise Continuum is a model for structuring a ‘virtual repository’ of architectural assets such as patterns, models, & architecture descriptions. TOGAF replaces the need to gradually develop enterprise architecture practices. Like any other framework, the enterprise security architecture life cycle needs to be managed properly. The TOGAF standard includes the concept of the Enterprise Continuum, which sets the broader context for an architect and explains how generic solutions can be leveraged and specialized in order to support the requirements of an individual organization. Meet some of the members around the world who make ISACA, well, ISACA.

Architecture layers. It was released as a reference model for enterprise architecture, offering insight into DoD’s own technical infrastructure, including how it’s structured, maintained and configured to align with specific requirements. In this course, you'll go through an in-depth explanation of the TOGAF® framework and Enterprise Architecture and learn how to enhance and mature architectures using the framework. The outcome of this phase is a maturity rating for any of the controls for current status and desired status. TOGAF's enterprise architecture. Information and technology power today’s advances, and ISACA empowers IS/IT professionals and enterprises. ISACA membership offers these and many more ways to help you all career long. The CMMI model has five maturity levels, from the initial level to the optimizing level.6 For the purpose of this article, a nonexistent level (level 0) is added for those controls that are not in place (figure 7). The enterprise frameworks SABSA, COBIT and TOGAF guarantee the alignment of defined architecture with business goals and objectives. It is important for all security professionals to understand business objectives and try to support them by implementing proper controls that can be simply justified for stakeholders and linked to the business risk. The Open Group Architecture Framework (TOGAF®) is one of the most widely accepted methods for developing enterprise architecture, providing a practical, step-by-step approach. Using these frameworks can result in a successful security architecture that is aligned with business needs: The simplified agile approach to initiate an enterprise security architecture program ensures that the enterprise security architecture is part of the business requirements, specifically addresses business needs and is automatically justified.
