XPA allows users to interact with ds9 and CIAO through a set of access points; access points are simply keywords that allow command-line interaction with the application.
Mosaic incorporated a set of access protocols and display standards originally developed at the European Organization for Nuclear Research CERNN) by Tim Berners-Lee for a new Internet application called the World Wide Web (WWW).
A gate is a form of pointer protected cryptographically, which references a segment and specifies a set of access rights for this segment.
To better adapt to changing requirements, and assist designers to customize access control policies, this paper proposes a set of access control features, i.e., small components that realize specific capabilities of access control models.
Moreover, we are given a set of access cable types, each with a cost per unit length and a capacity such that the cost per capacity decreases from small to large cables, and a core cable type of infinite capacity.
We assume that a set of access rules is given to the parties to regulate the data sharing, and such rules are defined over the join operations over the relational data.
To assist designers to visualize access control policies separated from non-security concerns, this paper proposes a set of access control diagrams, i.e., extensions to the UML to represent three main access control models: role-based access control (RBAC), mandatory access control (MAC), and discretionary access control (DAC).
Based on a set of access-control rules encoded as relational table rows, the mechanism determines via a single SQL query whether a user who accesses patient data from a specific application is authorized to perform a requested operation on a specified data object.
Decisions on powering-on a set of access points (APs), via the assignment of one power level (PL) to each opened AP, and decisions on the assignment of the user terminals (UTs) to the opened APs, have to be taken simultaneously.
A user u ∈ U has a set of credentials R u and an application m ∈ M has a set of access rights A m.
