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.
The Biba Model or Biba Integrity Model developed by Kenneth J. Biba in 1975, [1] is a formal state transition system of computer security policy describing a set of access control rules designed to ensure data integrity. Data and subjects are grouped into ordered levels of integrity.
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 ...
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. [46]
Microsoft Entra ID (formerly known as Microsoft Azure Active Directory or Azure AD) is a cloud-based identity and access management (IAM) solution. It is a directory and identity management service that operates in the cloud and offers authentication and authorization services to various Microsoft services, such as Microsoft 365, Dynamics 365, Microsoft Azure and third-party services.

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).
