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.
To change this template's initial visibility, the |state= parameter may be used: {{Microsoft Azure Services Platform | state = collapsed}} will show the template collapsed, i.e. hidden apart from its title bar. {{Microsoft Azure Services Platform | state = expanded}} will show the template expanded, i.e. fully visible.
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.
ISO/IEC 27001 is an international standard to manage information security.The standard was originally published jointly by the International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC) in 2005, [1] revised in 2013, [2] and again most recently in 2022.

Regarding cloud resources, Microsoft Azure offers two deployment models: the "classic" model and the Azure Resource Manager. [75] In the classic model, each resource, like a virtual machine or SQL database, had to be managed separately, but in 2014, [ 75 ] Azure introduced the Azure Resource Manager, which allows users to group related services.
Ciphertext-policy ABE (CP-ABE) is a type of public-key encryption. In the CP-ABE, the encryptor controls the access strategy. The main research work of CP-ABE is focused on the design of the access structure. A Ciphertext-policy attribute-based encryption scheme consists of four algorithms: Setup, Encrypt, KeyGen, and Decrypt. [34]
Security Functional Requirements (SFRs) – specify individual security functions which may be provided by a product. The Common Criteria presents a standard catalogue of such functions. For example, a SFR may state how a user acting a particular role might be authenticated. The list of SFRs can vary from one evaluation to the next, even if two ...
