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 number of files in the ''Sensitive Corporate Documents'' folder is 4. This can be verified by initiating a remote connection to the target machine from the ''Attacker Machine-1'' using Theef client. Theef is a Remote Access Trojan (RAT) that allows an attacker to remotely control a victim's machine and perform various malicious activities. To connect to the target machine using Theef client, one can follow these steps:

Launch Theef client from Z:\CCT-Tools\CCT Module 01 Information Security Threats and Vulnerabilities\Remote Access Trojans (RAT)\Theef on the ''Attacker Machine-1''.

Enter the IP address of the target machine (20.20.10.26) and click on Connect.

Wait for a few seconds until a connection is established and a message box appears saying ''Connection Successful''.

Click on OK to close the message box and access the remote desktop of the target machine.

Navigate to the Documents directory and locate the ''Sensitive Corporate Documents'' folder.

Open the folder and count the number of files in it. The screenshot below shows an example of performing these steps: Reference: [Theef Client Tutorial], [Screenshot of Theef client showing remote desktop and folder]

Testing is the tier of the secure application development lifecycle that involves checking the application performance in the above scenario. Secure application development is a process that involves designing, developing, deploying, and maintaining software applications that are secure and resilient to threats and attacks. Secure application development can be based on various models or frameworks, such as SDLC (Software Development Life Cycle), OWASP (Open Web Application Security Project), etc. Secure application development consists of various tiers or stages that perform different tasks or roles. Testing is a tier of the secure application development lifecycle that involves verifying and validating the functionality and security of software applications before releasing them to end users. Testing can include various types of tests, such as unit testing, integration testing, system testing, performance testing, security testing, etc. Testing can be used to check the application performance and identify any errors, bugs, or vulnerabilities in the software applications. In the scenario, a software company develops new software products by following the best practices for secure application development. Dawson, a software analyst, is responsible for checking the performance of applications in the client's network to determine any issue faced by end users while accessing the application. This means that he performs testing for this purpose. Development is a tier of the secure application development lifecycle that involves creating and coding software applications according to the design and specifications. Staging is a tier of the secure application development lifecycle that involves deploying software applications to a simulated or pre-production environment for testing or evaluation purposes. Quality assurance (QA) is a tier of the secure application development lifecycle that involves ensuring that software applications meet the quality standards and expectations of end users and stakeholders

Private cloud is the type of cloud deployment model that the company implemented in this scenario. Cloud computing is a model that provides on-demand access to shared and scalable computing resources, such as servers, storage, networks, applications, etc., over the internet or a network. Cloud computing can have different types based on its service or deployment model. A cloud deployment model defines how and where the cloud infrastructure and services are hosted and accessed . A cloud deployment model can have different types, such as public cloud, private cloud, hybrid cloud, community cloud, etc. A private cloud is a type of cloud deployment model that provides exclusive access to cloud infrastructure and services to a single organization or entity . A private cloud can be hosted within or outside the organization's premises and managed by the organization or a third-party provider . A private cloud can be used to secure sensitive data from external access and maintain full control over the corporate data . In the scenario, the company decided to implement the cloud infrastructure within its corporate firewall to secure sensitive data from external access. The company invested heavily in creating a cloud architecture within its premises to manage full control over its corporate data. This means that the company implemented a private cloud for this purpose. A multi-cloud is not a type of cloud deployment model, but a term that describes a strategy that uses multiple public or private clouds from different providers for different purposes or functions . A public cloud is a type of cloud deployment model that provides open access to cloud infrastructure and services to multiple organizations or entities over the internet . A public cloud can be hosted and managed by a third-party provider that owns and operates the cloud infrastructure and services . A community cloud is a type of cloud deployment model that provides shared access to cloud infrastructure and services to multiple organizations or entities that have common interests or goals
