The nodes and edges of this graph are very similar to triples in the Resource Description Framework (RDF) data format. [1] ReBAC systems allow hierarchies of relationships, and some allow more complex definitions that include algebraic operators on relationships such as union, intersection, and difference.
Role-based access control is a policy-neutral access control mechanism defined around roles and privileges. The components of RBAC such as role-permissions, user-role and role-role relationships make it simple to perform user assignments. A study by NIST has demonstrated that RBAC addresses many needs of commercial and government organizations. [4]
Graph-based access control (GBAC) is a declarative way to define access rights, task assignments, recipients and content in information systems. Access rights are granted to objects like files or documents, but also business objects such as an account.
Unlike role-based access control (RBAC), which defines roles that carry a specific set of privileges associated with them and to which subjects are assigned, ABAC can express complex rule sets that can evaluate many different attributes. Through defining consistent subject and object attributes into security policies, ABAC eliminates the need ...
The resulting graph is a property graph, which is the underlying graph model of graph databases such as Neo4j, JanusGraph and OrientDB where data is stored in the nodes and edges as key-value pairs. In effect, code property graphs can be stored in graph databases and queried using graph query languages.
Lua scripts may load extension modules using require, [20] just like modules written in Lua itself, or with package.loadlib. [22] When a C library is loaded via require ( 'foo' ) Lua will look for the function luaopen_foo and call it, which acts as any C function callable from Lua and generally returns a table filled with methods.
Rexx (Restructured Extended Executor) is a programming language that can be interpreted or compiled. It was developed at IBM by Mike Cowlishaw . [ 6 ] [ 7 ] It is a structured, high-level programming language designed for ease of learning and reading.
In distributed computing, a remote procedure call (RPC) is when a computer program causes a procedure (subroutine) to execute in a different address space (commonly on another computer on a shared computer network), which is written as if it were a normal (local) procedure call, without the programmer explicitly writing the details for the remote interaction.
