Non-routing dual-homed hosts are the type of bastion hosts configured by Elliott in the above scenario. A bastion host is a system or device that is exposed to the public internet and acts as a gateway or a proxy for other systems or networks behind it. A bastion host can be used to provide an additional layer of security and protection for internal systems or networks from external threats and attacks . A bastion host can have different types based on its configuration or functionality. A non-routing dual-homed host is a type of bastion host that has two network interfaces: one connected to the public internet and one connected to the internal network. A non-routing dual-homed host does not allow any direct communication between the two networks and only allows specific services or applications to pass through it . A non-routing dual-homed host can be used to isolate and secure internal systems or networks from external access . In the scenario, Elliott was appointed to test a newly developed application deployed over an organizational network using a bastion host. Elliott initiated the process by configuring the non-reusable bastion host. He then tested the newly developed application to identify the presence of security flaws that were not yet known; further, he executed services that were not secure. This means that he configured a non-routing dual-homed host for this purpose. An external services host is a type of bastion host that provides external services, such as web,email, FTP, etc., to the public internet while protecting internal systems or networks from direct access . A victim machine is not a type of bastion host, but a term that describes a system or device that has been compromised or infected by an attacker or malware . A one-box firewall is not a type of bastion host, but a term that describes a firewall that performs both packet filtering and application proxy functions in one device . 

The use of authorized RTU and PLC commands is the security control implemented by Hayes in the above scenario. RTU (Remote Terminal Unit) and PLC (Programmable Logic Controller) are devices that control and monitor industrial processes, such as power generation, water treatment, oil and gas production, etc. RTU and PLC commands are instructions that are sent from a master station to a slave station to perform certain actions or request certain data. The use of authorized RTU and PLC commands is a security control that fortifies the IDMZ (Industrial Demilitarized Zone) against cyber-attacks by ensuring that only valid and authenticated commands are executed by the RTU and PLC devices. Point-to-point communication is a communication method that establishes a direct connection between two endpoints. MAC authentication is an authentication method that verifies the MAC (Media Access Control) address of a device before granting access to a network. Anti-DoS solution is asecurity solution that protects a network from DoS (Denial-of-Service) attacks by filtering or blocking malicious traffic.

Exception handling is a secure application design principle that states that the application should handle errors and exceptions gracefully and securely, without exposing sensitive information or compromising the system’s functionality. Exception handling can help prevent attackers from exploiting errors or exceptions to gain access to data or resources or cause denial-of-service attacks. In the scenario, Miguel identified a flaw in the end-point communication that can disclose the target application’s data, which means that the application did not meet the exception handling principle.
