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.
A hierarchy of resources may be defined, so that a number of levels of locking can be implemented. For instance, a hypothetical database might define a resource hierarchy as follows: Database; Table; Record; Field; A process can then acquire locks on the database as a whole, and then on particular parts of the database. A lock must be obtained ...
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.
Windows Server operating systems include it as a set of processes and services. [1] [2] Originally, only centralized domain management used Active Directory. However, it ultimately became an umbrella title for various directory-based identity-related services. [3] A domain controller is a server running the Active Directory Domain Services (AD ...
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.
Azure functions are used in serverless computing architectures, where subscribers can execute code as an event-driven Function-as-a-Service without managing the underlying server resources. [45] Customers using Azure functions are billed based on per-second resource consumption and executions.
Cloud computing and storage provide users with the capabilities to store and process their data in third-party data centers. [1] Organizations use the cloud in a variety of different service models (with acronyms such as SaaS, PaaS, and IaaS) and deployment models (private, public, hybrid, and community).
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.
