TOGAF is owned by The Open Group . For purposes of this class, the layers that we will focus on follow the structure below, with additional information included related to security, evaluations and deployments. TOGAF replaces the need to gradually develop enterprise architecture practices. Note: Some of the frameworks are considering adding Security as it's own layer or architecture type. The enterprise frameworks SABSA, COBIT and TOGAF guarantee the alignment of defined architecture with business goals and objectives. Architecture Layers . This maturity can be identified for a range of controls. Following a framework will give a team launching EA as a new practice a way to assemble and organize a cohesive set of models for use across the enterprise. DataInformation_architecture_layer. The first phase measures the current maturity of required controls in the environment using the Capability Maturity Model Integration (CMMI) model. TOGAF is a management framework that features and promotes the role of architects. SABSA layers and framework create and define a top-down architecture for every requirement, control and process available in COBIT. 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. It is based on an iterative process model supported by best practices and a re-usable set of existing architecture assets. This is done by creating the architecture view and goals, completing a gap analysis, defining the projects, and implementing and monitoring the projects until completion and start over (figure 5). Beyond certificates, ISACA also offers globally recognized CISA®, CRISC™, CISM®, CGEIT® and CSX-P certifications that affirm holders to be among the most qualified information systems and cybersecurity professionals in the world. Planning, implementation and governance of enterprise information architecture, capabilities are typically expressed in general and high-level terms and typically require a combination of organization, people, processes, and technology to achieve, correspondingly, it structures architects thinking by dividing the architecture description into domains, layers, or views, and offers models. In this phase, the ratings are updated and the management team has visibility of the progress. Traditionally, security architecture consists of some preventive, detective and corrective controls that are implemented to protect the enterprise infrastructure and applications.
