Enterprise information security architecture is the practice of designing, constructing and maintaining information security strategies and policies in enterprise organisations. A subset of enterprise architecture , information security frameworks are often given their own dedicated resources in larger organisations and are therefore ...
Code diagrams (level 4): provide additional details about the design of the architectural elements that can be mapped to code. The C4 model relies at this level on existing notations such as Unified Modelling Language (UML) , Entity Relation Diagrams (ERD) or diagrams generated by Integrated Development Environments (IDE) .
The Resource Oriented Architecture, as documented by Leonard Richardson and Sam Ruby in their 2007 book RESTful Web Services, [3] gives concrete advice on specific technical details. Naming these collections of guidelines "Resource Oriented Architecture" may allow developers to discuss the benefits of an architecture in the context of ROA.
P = Permissions = An approval of a mode of access to a resource; SE = Session = A mapping involving S, R and/or P; SA = Subject Assignment; PA = Permission Assignment; RH = Partially ordered Role Hierarchy. RH can also be written: ≥ (The notation: x ≥ y means that x inherits the permissions of y.) A subject can have multiple roles.
PERA Reference model: Decision-making and control hierarchy, 1992. Purdue Enterprise Reference Architecture (PERA), or the Purdue model, is a 1990s reference model for enterprise architecture, developed by Theodore J. Williams and members of the Industry-Purdue University Consortium for Computer Integrated Manufacturing.
Enterprise architecture regards the enterprise as a large and complex system or system of systems. [3] To manage the scale and complexity of this system, an architectural framework provides tools and approaches that help architects abstract from the level of detail at which builders work, to bring enterprise design tasks into focus and produce valuable architecture description documentation.
The documentation of the Enterprise Architecture should include a discussion of principles and goals. [Note 1] For example, the agency's overall management environment, including the balance between centralization and decentralization and the pace of change within the agency, should be clearly understood when developing the Enterprise ...
The Zachman Framework of enterprise architecture. The Zachman Framework is an enterprise ontology and is a fundamental structure for enterprise architecture which provides a formal and structured way of viewing and defining an enterprise. The ontology is a two dimensional classification schema that reflects the intersection between two ...
