Role-based access control (RBAC) is an approach to restricting system access to authorized users and implementing mandatory or discretionary access control. RBAC is a policy-neutral access control mechanism defined around roles and privileges. It is a flexible access control technology that allows it to implement discretionary access control (DAC) or mandatory access control (MAC) without any complication.
In RBAC, access to resources is based on the roles of individual users within an organization. The roles in RBAC refer to the levels of access that employees have to the network. RBAC can be used to facilitate administration of security in large organizations with hundreds of users and thousands of permissions.
RBAC has several benefits, including reducing administrative work and IT support, maximizing operational efficiency, improving compliance, increasing visibility, reducing costs, and decreasing the risk of breaches and data leakage. By not allowing user access to certain processes and applications, companies can conserve or more cost-effectively use resources such as network bandwidth, memory, and storage.
Azure RBAC is an authorization system built on Azure Resource Manager that provides fine-grained access management to Azure resources. It helps manage who has access to Azure resources, what they can do with those resources, and what areas they have access to. Azure RBAC allows users to manage virtual machines, virtual networks, SQL databases, and all resources in a resource group.
In summary, RBAC is an access control mechanism that restricts system access to authorized users based on their roles and privileges. It has several benefits, including reducing administrative work, maximizing operational efficiency, improving compliance, increasing visibility, reducing costs, and decreasing the risk of breaches and data leakage. Azure RBAC is an authorization system built on Azure Resource Manager that provides fine-grained access management to Azure resources.
