Discretionary access control mechanism is based on data owner's discretion. In Mandatory access control mechanism user and resources are classified with security labels. In role based access control the data is
These models have different characteristics, which could impact the behavior of an access control mechanism for IoT. We provide in this section, an overview of the most popular access control models. • Discretionary Access Control (DAC) (Li, 2011): DAC is considered as an identity-based ...

The IAM system is designed to reduce the security risk exposure of your data by managing access controls over the lifecycle of the identified entity. It denies all requests by default — with the exception of requests that comply with the access control mechanism. ...

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
This paper presents an approach for providing access control in OSQL, an object-oriented database language that supports, among others, user-defined abstract data types, multiple inheritance, and late binding. The authorization scheme is based on a singl
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...
2.1 Access Control as a Security Concept Unauthorized access to sensitive data is one of the main challenging issues in IT security. Access control is a security mechanism that regulates the actions that users can/cannot perform on system resources. Access control policies are used to manage author...
The first and second datacenters may be in different locations or they may be in the same location. Since the data in the second datacenter needs to be the same as the data in the first datacenter, a synchronization mechanism is typically employed to handle synchronization of the data. If ...
