Uber relies on microservices to support its operations. Microservices necessitate a flexible authorization policy model to satisfy their unique authorization requirements. Attribute-based access control (ABAC) offers a dynamic, context-aware, and risk-in
2 Motivations for Attribute-based Access Control - GridShib2动机,基于属性的访问控制网格模式结构 热度: Role-based Access Control (RBAC) - Information Technology 基于角色的访问控制(RBAC)-信息技术 热度: A Cloud-Based Access Control Scheme with User Revocation and Attribute Update ...
With PBAC, Dr. Adams can access patient records relating to his expertise during office hours. However, he can’t access billing or patient admission records. This prevents our cardiologist from making care decisions based on administrative data, which is a conflict of interest. ABAC versus RBAC ...
In recent years, attribute-based access control (ABAC) models have been widely used in big data and cloud computing. However, with the growing importance of data content, using data content to assist authorization for access controls has become more common. In this paper, we propose a dynamic...
One scheme was proposed to protect financial customers' privacy by using attribute-based access controls (Gai et al., 2015; Smari et al., 2014). This approach only allows those third parties that are configured as the trustable parties to decrypt their data either fully or partially. Show ...
In this work, we propose attribute-based authorizations to satisfy the k-anonymity property: the set of credentials submitted by a subject during an access control operation should be equal to at least k other such sets received by the counterpart during earlier access controls operations. We ...
aws:ResourceTag/tag-key: Controls access based on whether or not the tag key-value pair on a DynamoDB table or index matches the tag key and value in a policy. This condition key is relevant to all APIs that operate on an existing table or index. The dynamodb:ResourceTag conditions...
Use the attribute-based semantic access control to restrict the data accesses. • Achieve high level security by avoiding unexpected operations on the cloud side. Abstract As one of the most significant issues in the financial industry, customers’ privacy information protection has been considered ...
(childO, processedControls); } else if (childO is IEnumerable) { foreach (object item in (IEnumerable)childO) { if (item is System.ComponentModel.Component) { CheckSecurity(item, processedControls); } } } } } } private bool HasAccess(string controlName, string operationName) { bool ...
Attribute-Based Encryption is a more expansive type of public key encryption that allows for flexible policy-based access controls that are cryptographically (that is, mathematically) enforced. Instead of encrypting data to a single user, it is now possible to encrypt it so that the data can be...
