Which of the following practices for secure server configuration uses RBAC (Role-Based Access Control) to limit user access to a host?

The practice of host lockdown is centered on implementing security measures that restrict access to a server based on the principle of least privilege through Role-Based Access Control (RBAC). In RBAC, user permissions are assigned according to roles rather than to individuals directly, which simplifies access management and enhances security.

By using RBAC, only users with the necessary role can access specific functions or data on the host system, effectively limiting exposure and reducing the potential attack surface. This structured approach ensures that users can only perform tasks pertinent to their responsibilities, thereby preventing unauthorized access or alterations.

In the context of cloud security and server configuration, host lockdown plays a crucial role in safeguarding the server from potential threats by ensuring that only authorized roles are granted access to sensitive areas of the server. This goes beyond merely closing unneeded ports or disabling services, as it incorporates a wider organizational policy regarding user rights and access.

Host patching, host hardening, and host mapping, while related to server security, do not primarily focus on the application of RBAC to limit user access. Host patching involves updating software to fix vulnerabilities, host hardening refers to making a system more secure through various configurations, and host mapping generally pertains to network topology or asset inventory, which do not directly implement
