What method is used to assign different levels of access for firewall management?

Role-based access control (RBAC) is a method that is used to assign different levels of access to firewall management based on the roles of individual users within an organization. This approach allows for the delegation of permissions to users based on their job functions, ensuring that individuals only have access to the resources necessary for their roles. By implementing RBAC, organizations can enhance security and compliance by minimizing the risk of unauthorized access to sensitive data or configurations.

In a firewall management context, this means that an administrator can configure the system such that a network technician, for instance, may have permissions to monitor traffic but not to change firewall rules, while a network engineer might have full access to make modifications. This structured approach to permissions not only improves security but also helps streamline operations by clearly defining what each user can or cannot do.

Other methods discussed, such as user authentication, network segmentation, and access control lists, serve different purposes in network security and management. User authentication is critical for verifying identity before access is granted, while network segmentation is used to partition a network to reduce the attack surface. Access control lists help dictate what traffic is permissible across a network but do not inherently manage user roles and permissions in an intuitive or dynamic manner like RBAC does.
