Verified Answer: The type of attack that enables an attacker to read and modify the transmitted data packets and send their own requests to the client is:

C . TCP hijacking

TCP Hijacking Definition: TCP hijacking is a type of cyber attack where an attacker takes control of a communication session between two entities12.

Attack Mechanism: The attacker intercepts and manipulates data packets being sent over the network, allowing them to read, modify, and insert their own packets into the communication stream1.

Impact on Security: This attack can lead to unauthorized access to sensitive data and systems, and it can be used to impersonate the victim, resulting in data breaches and other security incidents1.

Prevention Measures: Implementing security measures such as encryption, using secure protocols, and monitoring network traffic can help prevent TCP hijacking attacks1.

TCP hijacking is particularly relevant to cloud environments where misconfigurations can leave systems vulnerable. It is crucial for A .R.T.I.E. to ensure proper security configurations and adopt measures to protect against such attacks as part of their migration to the public cloud and overall cybersecurity strategy12.

For the question regarding the type of edge security risk A .R.T.I.E. is primarily exposed to, let's analyze the options:

Data risk: This refers to the risk associated with the storage, processing, and transmission of data. Given that A .R.T.I.E. is a social media company with a platform for sharing content and making in-app purchases, there is a significant amount of data being handled, which could be at risk if not properly secured.

Internet of Things (IoT) risk: This involves risks associated with IoT devices, which may not be applicable in this context as A .R.T.I.E. is described as a social media company rather than one that specializes in IoT devices.

Protection risk: This could refer to the overall security measures in place to protect the company's assets. Since A .R.T.I.E. has moved some applications to the public cloud and operates an internal network accessible via VPN, the protection of these assets is crucial.

Hardware risk: This involves risks related to the physical components of the network. The case study does not provide specific details about hardware vulnerabilities, so this may not be the primary concern.

Considering the case study's focus on data handling, cloud migration, and the need for secure solutions, Data risk seems to be the most relevant edge security risk A .R.T.I.E. is exposed to. The decentralization of compute and data creation, along with the inability to physically secure the edge as one would with a data center, increases the risk to the data being processed and stored at the edge.

Remember, when preparing for assessments like the Dell Security Foundations Achievement, it's important to thoroughly review the study materials provided, understand the key concepts, and apply them to the scenarios presented in the case studies. Good luck with your preparation!

A data breach occurs when confidential information is accessed or disclosed without authorization. In the scenario described, an employee unintentionally sent out a slide deck containing personal information of a colleague. This incident falls under the category of a data breach because it involves the exposure of personal data.

The Dell Security Foundations Achievement covers a broad range of topics, including the NIST Cybersecurity Framework, ransomware, and security hardening. It aims to validate knowledge on various risks and attack vectors, as well as the techniques and frameworks used to prevent and respond to possible attacks, focusing on people, process, and technology1.

In the context of the Dell Security Foundations Achievement, understanding the nature of different types of cyber threats is crucial. A data breach, as mentioned, is an incident where information is accessed without authorization. This differs from:

A ransomware attack (A), which involves malware that encrypts the victim's files and demands a ransom for the decryption key.

An advanced persistent threat , which is a prolonged and targeted cyberattack in which an intruder gains access to a network and remains undetected for an extended period.

A supply chain attack (D), which occurs when a malicious party infiltrates a system through an outside partner or provider with access to the system and its data.

Therefore, based on the information provided and the context of the Dell Security Foundations Achievement, the correct answer is B. Data breach.
