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 . 

Availability is the information security element that ensures that Stella’s transaction status is immediately reflected in her bank account in this scenario. Information security is the practice of protecting information and information systems from unauthorized access, use, disclosure, modification, or destruction. Information security can be based on three fundamental principles: confidentiality, integrity, and availability. Confidentiality is the principle that ensures that information is accessible only to authorized parties and not disclosed to unauthorized parties. Integrity is the principle that ensures that information is accurate, complete, and consistent and not altered or corrupted by unauthorized parties. Availability is the principle that ensures that information and information systems are accessible and usable by authorized parties when needed. In the scenario, Stella purchased a smartwatch online using her debit card. After making payment for the product through the payment gateway, she received a transaction text message with a deducted and available balance from her bank. This means that her transaction status was immediately reflected in her bank account, which indicates that availability was ensured by her bank’s information system. 

The correct answer is B, as it describes the information security element that was described in the above scenario. Non-repudiation is an information security element that ensures that a party cannot deny sending or receiving a message or performing an action. In the above scenario, non-repudiation was described, as Kayden could not deny company’s message, and company could not deny Kayden’s signature. Option A is incorrect, as it does not describe the information security element that was described in the above scenario. Availability is an information security element that ensures that authorized users can access and use information and resources when needed. In the above scenario, availability was not described, as there was no mention of access or use of information and resources. Option C is incorrect, as it does not describe the information security element that was described in the above scenario. Integrity is an information security element that ensures that information and resources are accurate and complete and have not been modified by unauthorized parties. In the above scenario, integrity was not described, as there was no mention of accuracy or completeness of information and resources. Option D is incorrect, as it does not describe the information security element that was described in the above scenario. Confidentiality is an information security element that ensures that information and resources are protected from unauthorized access and disclosure.In the above scenario, confidentiality was not described, as there was no mention of protection or disclosure of information and resources.
