Which statement about rule-based access control is true?
Learn about role-based access control (RBAC) in Data Protection 101, our series on the fundamentals of information security. Show Definition of Role-Based Access Control (RBAC)Role-based access control (RBAC) restricts network access based on a person's role within an organization and has become one of the main methods for advanced access control. The roles in RBAC refer to the levels of access that employees have to the network. Employees are only allowed to access the information necessary to effectively perform their job duties. Access can be based on several factors, such as authority, responsibility, and job competency. In addition, access to computer resources can be limited to specific tasks such as the ability to view, create, or modify a file. As a result, lower-level employees usually do not have access to sensitive data if they do not need it to fulfill their responsibilities. This is especially helpful if you have many employees and use third-parties and contractors that make it difficult to closely monitor network access. Using RBAC will help in securing your company’s sensitive data and important applications. Examples of Role-Based Access ControlThrough RBAC, you can control what end-users can do at both broad and granular levels. You can designate whether the user is an administrator, a specialist user, or an end-user, and align roles and access permissions with your employees’ positions in the organization. Permissions are allocated only with enough access as needed for employees to do their jobs. What if an end-user's job changes? You may need to manually assign their role to another user, or you can also assign roles to a role group or use a role assignment policy to add or remove members of a role group. Some of the designations in an RBAC tool can include:
By adding a user to a role group, the user has access to all the roles in that group. If they are removed, access becomes restricted. Users may also be assigned to multiple groups in the event they need temporary access to certain data or programs and then removed once the project is complete. Other options for user access may include:
Benefits of RBACManaging and auditing network access is essential to information security. Access can and should be granted on a need-to-know basis. With hundreds or thousands of employees, security is more easily maintained by limiting unnecessary access to sensitive information based on each user’s established role within the organization. Other advantages include:
Best Practices for Implementing RBACImplementing a RBAC into your organization shouldn’t happen without a great deal of consideration. There are a series of broad steps to bring the team onboard without causing unnecessary confusion and possible workplace irritations. Here are a few things to map out first.
A core business function of any organization is protecting data. An RBAC system can ensure the company's information meets privacy and confidentiality regulations. Furthermore, it can secure key business processes, including access to IP, that affect the business from a competitive standpoint.

What is ruleWhat is the Rule/Role Based Access Control (RBAC) Model? The RBAC Model uses roles to grant access by placing users into roles based on their assigned jobs, Functions, or tasks. Rights and permissions are assigned to the roles. A user is placed into a role, thereby inheriting the rights and permissions of the role.

A router access control list that allows or denies traffic based on the characteristics of an IP packet is an example of rule-based access control.
Which type of access is a type of ruleExamples of Rules Based Access Control include situations such as permitting access for an account or group to a network connection at certain hours of the day or days of the week. As with MAC, access control cannot be changed by users. All access permissions are controlled solely by the system administrator.
