In this paper, an access control mechanism for collaborative video database production applications has been proposed, of which it subsumes the properties of DAC, MAC, and NAC. Moreover, our proposed mechanism is integrated with the intellectual property concerns by constructing an access control ...
Hence, their approach utilizes RBAC to control access to things on the Web. However, we think that the RBAC itself shows inappropriate aspects in a distributed network environment. Second, no lightweight mechanism is proposed to make RBAC supported by constrained devices. The RBAC-based ...
In this blog post, we will cover some tips and tricks on using the database role to manage user privileges and as an advanced access control mechanism for our database access. If you would like to learn about the basics of roles in MySQL and MariaDB, check out this blog post,Database ...
The MAC(mandatory access control) is often used security enhancing technique of operating system. LSM(Linux Security Modules)是得到Linus Torvalds本人支持的安全访问控制的底层架构,强制访问控制是操作系统安全增强技术中经常采用的方式。 3. This paper proposes a fine-grained XML inference control mechanism,...
The table parameter is specified through the same mechanism as a a parameter; a question mark ("?") is used in place of the appropriate table name. Note:In the current implementation only a single table column can be passed as a table parameter. If more than one column is specified, an...
Techniques are provided for access control in a system. A request is received for checking whether a subject has a privilege for a resource. A security class that defines a plurality of privileges tha
A Federated Capability-based Access Control Mechanism for Internet of Things (IoTs) The prevalence of Internet of Things (IoTs) allows heterogeneous embedded smart devices to collaboratively provide intelligent services with or without human intervention. While leveraging the large-scale IoT-based applica...
In casbin, an access control model is abstracted into a CONF file based on thePERM metamodel (Policy, Effect, Request, Matchers). So switching or upgrading the authorization mechanism for a project is just as simple as modifying a configuration. You can customize your own access control model...
whereorder_entryis the context namespace, andApp_security_contextis the trusted package that can set attributes in the context namespace. After you have created the context, you can set or reset the context attributes by using theDBMS_SESSION.SET_CONTEXTpackage. The values of the attributes you...
(a) automatically determined based on implemented access control policies across an IT infrastructure; and/or (b) centralized to facilitate easier visualization, management and administration; and/or (c) automatically tied to an access control mechanism that enforces policies associated with any ...
