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. 

 Risk and impact analysis is the threat-modeling step in which Martin evaluated the severity level of the threat in the above scenario. Threat modeling is a process that involves identifying, analyzing, and mitigating threats and risks to a system or network. Threat modeling can be used to improve the security and resilience of a system or network by applying various methods or techniques, such as STRIDE, DREAD, PASTA, etc. Threat modeling consists of various steps or phases that perform different tasks or roles. Risk and impact analysis is a threat-modeling step that involves assessing the likelihood and consequences of threats and risks to a system or network . Risk and impact analysis can be used to evaluate the severity level of threats and risks and prioritize them for mitigation . In the scenario, Martin received breaching alerts for an application. He identified that a vulnerability in the application allowed attackers to enter malicious input. Martin evaluated the threat severity and extent of damage that could be caused by this vulnerability. He then escalated the issue to the security management team to determine appropriate mitigation strategies. This means that he performed risk and impact analysis for this purpose. Identify vulnerabilities is a threat-modeling step that involves finding and documenting the weaknesses or flaws in a system or network that can be exploited by threats or risks . Application overview is a threat-modeling step that involves defining and understanding the scope, architecture, components, and functionality of a system or network .Decompose the application is a threat-modeling step that involves breaking down a system or network into smaller and simpler elements, such as data flows, processes, assets, etc.

 Turn the device ON if it is OFF, do not leave the device as it is if it is ON, and make sure that the device is charged are some of the points that Shawn must follow while preserving the digital evidence in the above scenario. Digital evidence is any information or data stored or transmitted in digital form that can be used in a legal proceeding or investigation. Digital evidence can be found on various devices, such as computers, mobile phones, tablets, etc. Preserving digital evidence is a crucial step in forensic investigation that involves protecting and maintaining the integrity and authenticity of digital evidence from any alteration or damage. Some of the points that Shawn must follow while preserving digital evidence are:

Turn the device ON if it is OFF: If the device is OFF, Shawn must turn it ON to prevent any data loss or encryption that may occur when the device is powered off. Shawn must also document any password or PIN required to unlock or access the device.

Do not leave the device as it is if it is ON: If the device is ON, Shawn must not leave it as it is or use it for any purpose other than preserving digital evidence. Shawn must also disable any network connections or communication features on the device, such as Wi-Fi, Bluetooth, cellular data, etc., to prevent any remote access or deletion of data by unauthorized parties.

Make sure that the device is charged: Shawn must ensure that the device has enough battery power to prevent any data loss or corruption that may occur due to sudden shutdown or low battery. Shawn must also use a write blocker or a Faraday bag to isolate the device from any external interference or signals.

Never record the screen display of the device is not a point that Shawn must follow while preserving digital evidence. On contrary, Shawn should record or photograph the screen display of the device to capture any relevant information or messages that may appear on the screen. Recording or photographing the screen display of the device can also help document any changes or actions performed on the device during preservation.
