Task-role-based access control model

TL;DR: In this paper, a computer implemented method of developing computer applications, the method comprising providing to multiple users access, over a network, to information on a data center, with a subgroup of the users having access to a sub-portion of the information that is different from the subportion accessible by the remaining tenants of the subgroup; communicating with the data center over the network employing a computer system associated with a user, to establish application functionality with the sub portion that may be accessed by additional parties authorized by the user.

TL;DR: The proposed access control model can not only ensure the secure sharing of resources among potential untrusted tenants, but also has the capacity to support different access permission to the same cloud user and gives him/her the ability to use multiple services securely.

TL;DR: The definition of process-related RBAC models at the modeling-level is an important prerequisite for the thorough implementation and enforcement of corresponding policies and constraints in a software system.

TL;DR: The core technologies including identity authentication, access control, and trust assessment, which are mainly relied on in the zero trust architecture are analyzed and compared to summarize the advantages and disadvantages, as well as the current challenges and future research trends.

TL;DR: This work presents a security model that reflects the structure of cooperative work, enabling users' security policies and other task requirements to be translated directly into access rights for those shared objects whose protection must be guaranteed for the successful outcome of cooperative tasks.

TL;DR: Enterprise environment needs application both RBAC and ABAC models, and these models have some limitations to apply to enterprise environment.

TL;DR: This report summarizes the Enterprise Security Workshop, which focused on public key infrastructure and authorization: current practice and future trends on PKI and enterprise security issues.
