Role-Based Access Control (RBAC)

What is RBAC?

Role-Based Access Control (RBAC) is a method of regulating access to computer or network resources based on the roles of individual users within an organization.

Key Concepts

• Roles: A set of permissions assigned to a user based on their responsibilities within the organization.
• Users: Individuals who have access to the system and are assigned one or more roles.
• Permissions: The access rights to perform actions on resources.
• Sessions: A mapping between a user and their active roles during a login session.

How to Implement RBAC

1. Identify the resources that require access control.
2. Define roles needed for your organization.
3. Assign permissions to each role.
4. Map users to roles based on their job functions.
5. Implement the RBAC model in your application or system.

class User:
    def __init__(self, username):
        self.username = username
        self.roles = []

class Role:
    def __init__(self, name):
        self.name = name
        self.permissions = []

class RBAC:
    def __init__(self):
        self.roles = {}
        self.users = {}

    def add_role(self, role):
        self.roles[role.name] = role

    def add_user(self, user):
        self.users[user.username] = user

    def assign_role(self, username, role_name):
        self.users[username].roles.append(role_name)

Best Practices

• Regularly review roles and permissions to ensure they align with current organizational needs.
• Implement least privilege access to minimize exposure of sensitive data.
• Utilize role hierarchies to simplify management of complex role structures.
• Provide training for users to understand their roles and permissions better.
