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 ...
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.
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 ...
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.
Computer operating systems provide different levels of access to resources. A protection ring is one of two or more hierarchical levels or layers of privilege within the architecture of a computer system. This is generally hardware-enforced by some CPU architectures that provide different CPU modes at the hardware or microcode level. Rings are ...
In computer security, an access-control list (ACL) is a list of permissions [a] associated with a system resource (object or facility). An ACL specifies which users or system processes are granted access to resources, as well as what operations are allowed on given resources. [1] Each entry in a typical ACL specifies a subject and an operation.
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.
This document includes a high-level architecture diagram depicting the structure of the system, such as the hardware, database architecture, application architecture (layers), application flow (navigation), security architecture and technology architecture. [1]
