Dell Security Foundations Achievement:The Dell Security Foundations Achievement documents emphasize the importance of threat intelligence in understanding and responding to cybersecurity incidents1.

The threat intelligence team’s capabilities align with the requirements ofA .R.T.I.E.to address their cybersecurity challenges effectively1.

For the question regarding the type of edge security riskA .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 thatA .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 asA .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. SinceA .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 riskseems to be the most relevant edge security riskA .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 deckcontaining 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.

The security hardening techniques should be matched with the corresponding source area as follows:

Operating System:Enables secure boot and removes unnecessary drivers.

Database:Implements Role-Based Access Control and removes unnecessary database services.

Network:Implements Intrusion Prevention System.

Server:Encrypts the host device using hardware trusted privilege.

Operating System Hardening:Involves enabling secure boot to ensure that only trusted software is loaded during the system startup and removing unnecessary drivers to minimize potential vulnerabilities1.

Database Hardening:Role-Based Access Control (RBAC) restricts system access to authorized users, and removing unnecessary services reduces the attack surface1.

Network Hardening:An Intrusion Prevention System (IPS) monitors network traffic for suspicious activity and takes action to prevent intrusions1.

Server Hardening:Encrypting the host device using hardware-based mechanisms like Trusted Platform Module (TPM) provides a secure environment for the server’s operating system1.

These matches are based on standard security practices that align with the Dell Security Foundations Achievement’s emphasis on security hardening across different areas of IT infrastructure1.

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 forA .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.

Control Mechanism Selection:

ForA .R.T.I.E.'s scenario, where the concern is about sharing and protecting data off-premises and ensuring that data can be used in decision-making without exposing it to unauthorized access, the most suitable control mechanism would be:

A. Proactive control mechanism

Proactive control mechanisms are designed to prevent security incidents before they occur.They include measures such as strong authentication, encryption, and access controls, which align withA .R.T.I.E.'s requirements for secure migration to the public cloud and maintaining data confidentiality during decision-making processes1234.

Data Encryption:Encrypting data at rest and in transit ensures that even if data is intercepted or accessed by unauthorized individuals, it remains unreadable and secure2.

Access Control:Implementing robust access control measures, such as role-based access control (RBAC) and multi-factor authentication (MFA), restricts data access to authorized personnel only34.

Firewalls and Network Security:Deploying firewalls and other network security measures helps to protect the cloud environment from unauthorized access and potential breaches2.

Security Monitoring:Continuous monitoring of the cloud environment allows for the early detection of potential security threats and vulnerabilities2.

Security Patching and Upgrades:Regularly updating and patching systems ensures that security measures are up-to-date and can defend against the latest threats2.

These proactive controls are essential forA .R.T.I.E.as they provide a comprehensive approach to securing data in the public cloud, align with the Dell Security Foundations Achievement’s focus on security hardening, and support the Zero Trust model, which assumes no implicit trust and verifies each request as though it originates from an open network5.
