information security architecture framework

Each layer has a different purpose and view. The picture below represents a one-dimensional view of enterprise architecture as a service-oriented architecture. Using frameworks such as COBIT or ISO 27001 can help identify a list of relevant security controls that can be used to develop a comprehensive security architecture that is relevant to business. More and more companies[citation needed] are implementing a formal enterprise security architecture process to support the governance and management of IT. effective combinations of operational processes, cultural behavior and Maintaining the accuracy of such data can be a significant challenge. An IT Security Framework is a set of guidelines or a template that outlines policies and procedures you can use in your workplace. Like other IT management frameworks, TOGAF helps businesses align IT goals with overall business goals, while helping to organize cross-departmental IT efforts. It must be a living process. Organizations find this architecture useful because it covers capabilities ac… Enterprise information security architecture frameworks is only a subset of enterprise architecture frameworks. An intermediate outcome of an architecture process is a comprehensive inventory of business security strategy, business security processes, organizational charts, technical security inventories, system and interface diagrams, and network topologies, and the explicit relationships between them. fabric of the business processes and is a key component of the organizational [1] This was published on 24 January 2006. 2. Often, multiple models and non-model artifacts are generated to capture and track the concerns of all stakeholders. This article will cover some of the major areas within Security Architecture and Design by looking at: design concepts, hardware architecture, OS and software architecture, security models, modes of operations, and some system evaluation methods, specifically CAP. Such exhaustive mapping of IT dependencies has notable overlaps with both metadata in the general IT sense, and with the ITIL concept of the configuration management database. What is the information security risk posture of the organization? A0008: Ability to apply the methods, standards, and approaches for describing, analyzing, and documenting an organization's enterprise information technology (IT) architecture (e.g., Open Group Architecture Framework [TOGAF], Department of Defense Architecture Framework [DoDAF], Federal Enterprise Architecture Framework [FEAF]). If we had to simplify the conceptual abstraction of enterprise information security architecture within a generic framework, the picture on the right would be acceptable as a high-level conceptual security architecture framework. The analogy of city-planning is often invoked in this connection, and is instructive. Business architecture, information architecture and technology architecture used to be called BIT for short. The SABSA methodology has six layers (five horizontals and one vertical). objective of an information security program is to establish a continuous, Based on what we know about what the organization wants to accomplish in the future, will the current security architecture support or hinder that? The inventories and diagrams are merely tools that support decision making. Establish a common "language" for information security within the organization. The process then cascades down to documenting discrete core competencies, business processes, and how the organization interacts with itself and with external parties such as customers, suppliers, and government entities. Organization charts, activities, and process flows of how the IT Organization operates, Suppliers of technology hardware, software, and services, Applications and software inventories and diagrams, Interfaces between applications - that is: events, messages and data flows, Intranet, Extranet, Internet, eCommerce, EDI links with parties within and outside of the organization, Data classifications, Databases and supporting data models, Hardware, platforms, hosting: servers, network components and security devices and where they are kept, Local and wide area networks, Internet connectivity diagrams, Closing gaps that are present between the current organization strategy and the ability of the IT security dimensions to support it, Closing gaps that are present between the desired future organization strategy and the ability of the security dimensions to support it. Natural Disaster 2. Successful application of enterprise information security architecture requires appropriate positioning in the organization. Enterprise information security architecture (EISA) is a part of enterprise architecture focusing on information security throughout the enterprise. of such a solution, the security team must define and implement strategic security posture is built on appropriate policies that are enforced by How is Cyber Security related to information security? Along with the models and diagrams goes a set of best practices aimed at securing adaptability, scalability, manageability etc. Since this publication, security architecture has moved from being a silo based architecture to an enterprise focused solution that incorporates business, information and technology. The users accessing the enterprise application can either be within the enterprise performing business roles such as developer, administrator, IT manager, quality approver, and others, or they may be outside the enterprise such as partners, vendors, customers, and outsourced business or support staff. Although often associated strictly with information security technology, it relates more broadly to the security practice of business optimization in that it addresses business security architecture, performance management and security process architecture as well. An effective architecture process must provide the consistent principles, mechanisms and guidelines that are used to derive the appropriate security solutions from business requirements so that organizations can become more effective and coordinated in their security practices. SABSA is a business-driven security framework for enterprises that is based on risk and opportunities associated with it. ", This page was last edited on 22 January 2020, at 11:34. Optimizing the EISA is done through its alignment with the underlying business strategy. Is the current architecture supporting and adding value to the security of the organization?
