What is role-based access control?Role-based access control (RBAC) is a method of restricting network access based on the roles of individual users within an enterprise. Show
RBAC ensures employees access only information they need to do their jobs and prevents them from accessing information that doesn't pertain to them. An employee's role in an organization determines the permissions that individual is granted and ensures lower-level employees can't access sensitive information or perform high-level tasks. In the role-based access control data model, roles are based on several factors, including authorization, responsibility and job competency. As such, companies can designate whether a user is an end user, an administrator or a specialist user. In addition, access to computer resources can be limited to specific tasks, such as the ability to view, create or modify files. Limiting network access is important for organizations that have many workers, employ contractors or permit access to third parties, like customers and vendors, which makes it difficult to monitor network access effectively. Companies that depend on RBAC are better able to secure their sensitive data and critical applications. Benefits of RBACThere are multiple benefits to using RBAC, including:
Best practices for role-based access control implementationsThere are a number of best practices organizations should follow for implementing RBAC, including:
RBAC vs. ABACRole-based access control and attribute-based access control (ABAC) are both types of access control methods, but their approaches are different. While RBAC grants access rights depending on the roles of users, ABAC controls access based on a combination of attributes, i.e., user attributes, resource attributes, attributes associated with the system or application to be accessed and environmental attributes. User attributes may include name, nationality, organization, ID, role and security clearance. Examples of resource attributes include owner, name and data creation date, while environmental attributes include access location, time of access and threat levels. In addition to simplifying access management, ABAC enables companies to reduce risks from unauthorized access and helps to centralize auditing. Organizations should use RBAC for coarse-grained access control, such as giving all professors in a university access to Google for doing research or giving all contractors access to corporate email. On the other hand, companies should use ABAC for fine-grained access control or if they need to make decisions under specific conditions, e.g., giving professors access to Google only if they work in building X and teach freshman classes.

Which access control model allows owners to determine who can access the files?1. Mandatory Access Control (MAC) The Mandatory Access Control (MAC) model gives only the owner and custodian management of the access controls.
What access control model allows the owner of the resources to define what users may access it?Discretionary Access Control (DAC) –
DAC is a type of access control system that assigns access rights based on rules specified by users. The principle behind DAC is that subjects can determine who has access to their objects.
