NEW QUESTION # 11
To optimize network performance and reliability, low latency network path for customer traffic, A.R.T.I.E created a modern edge solution. The edge solution helped the organization to analyze and process diverse data and identify related business opportunities. Edge computing also helped them to create and distribute content and determine how the users consume it. But as compute and data creation becomes more decentralized and distributed,A .R.T.I.E.was exposed to various risks and security challenges inevitably became more complex.
Unlike the cloud in a data center, it is physically impossible to wall off the edge.
Which type of edge security riskA .R.T.I.E.is primarily exposed?
- A. Data risk
- B. Protection risk
- C. Internet of Things risk
- D. Hardware risk
Answer: A
Explanation:
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 Zero Trust security strategy is defined by which of the primary approaches?
- A. Micro-segmenting and Multi-factor authentication
- B. VPNs and IAM
- C. IAM and security awareness training
- D. Network segmenting and access control
Answer: A
Explanation:
Topic 1, Case Study Scenario
It is recommended that you read through the case study before answering any questions. You can always return to the case study while viewing any of the twenty questions.
Introduction
As the threat landscape has grown over past years and continues to evolve unpredictably, cyber-attacks on organizations are now unavoidable. Security is no longer about averting attacks; it is all about preparing for them.
In recent years, large corporate data breaches have impacted millions of customers and revealed personal information that can be used in follow-on crimes. The longer a cyber-attack goes unnoticed, the more damage it does to the business and the more money and time it will cost to recover.
Hackers steal financial, medical, and other sensitive information to sell online or use in cybercrimes. This unpredictable security threat landscape has resulted in a challenging scenario for all organizations.
Business Description
A:R.T.I.E.is a midsize social media company whose key customers are 18- to 28-year-olds. Using the organization's platform, customers can share content such as photos, videos and post status updates and views.
The organization has a in-built messenger app that helps users to interact. The platform also has an option to make in-app purchases and play games with other users.
One key characteristic ofA .R.T.I.E.is that it supports social influencers and has attracted large firms as advertisers.
With 450 employees, who work from different locations, the main goal ofA .R.T.I.E.is to provide high quality of services to a user base of 15K individuals and associates. The employees have access to the apps, platform, data, and systems through an internal network that uses a virtual private network (VPN) to secure access from remote locations.
Business Problem
Senior management ofA .R.T.I.E.expects the core business to continue to grow rapidly due to an increase in user traffic and increased demand of its advertising platform especially by big organizations.
Based on their current business-critical needs for their solutions and client base, the organization is planning to move towards a global operational geography and have migrated some of its key applications to the public cloud. Deployment of the applications to the public cloud provides:
. Ability to scale.
. Higher data transfer speeds and more efficient access management.
. Faster time-to-market and better control of IT costs.
However, with progress comes new challenges as public cloud environments broaden the attack surface from which attackers can try to gain unauthorized access to an organization's resources.A .R.T.I.E.also must comply with various regulations and cloud security controls and have to come up with holistic security capabilities that ensure security across the organization, core-to-edge-to-cloud.
Even though the IT team of the organization constantly monitor their IT environment and assets along with watching for unauthorized profiles, information disclosure, fake accounts, and other threats, the CIO of A.R.I.T.E. is aware that the nature of their business being an open platform makes them a prime target for attackers and other cybercriminals.
Due to the growing business and untrained employees, the organization is constantly under the fear of threat.
This fear increased tenfold when they had discovered two back-to-back cyberattacks resulting in unauthorized access to databases containing user information.
In the first attack, the attackers performed data theft techniques to exfiltrate vulnerable information and held internal systems for ransom. This incident led to the company negotiating a ransom payment to recover data.
Also, an unexplained surge in requests to a single webpage occurred along with unusual network traffic patterns which indicated a second attack. These attacks were concerning not only for the financial impact but also for the amount of data exposed.
Requirements
The key requirements to address the primary challenges to the business includes:
. Understanding the cyber threat landscape specific to the organizational risk tolerance.
. Secure migration of applications to the public cloud.
. Implement a suitable security framework to tackle current and emerging threats.
. Identify possible vulnerabilities and threats.
. Create an incident management plan based on knowledge, experience, and real-time information to prevent future attacks.
. Learn about the tools and technologies used to avert the attacks and determine which tools will be appropriate for them.
. Take measures to implement secure solutions and control: Zero Trust, Security hardening, IAM techniques.
Dell Services Team
To improve the overall cyber security posture and implement better security policies as the company grows,A.R.T.I.E.contacted Dell Services.
Dell clients use their services and solutions to collectively monitor thousands of devices, systems, and applications. Some clients have a significant workforce with minimal IT knowledge, which opens greater security risks and technological gaps.
Strategic advisory team

The objective was to consolidate data from the organization's multiple sources such as: networks, servers, databases, applications, and so on; thus, supports centralized monitoring.
NEW QUESTION # 13
During the analysis, the threat intelligence team disclosed a possible threat which went unnoticed when anA
.R.T.I.E.employee sent their friend a slide deck containing the personal information of a colleague. The exposed information included employee first and last names, date of birth and employee ID.
What kind of attack occurred?
- A. Supply chain attack
- B. Advance Persistent Threat
- C. Ransomware
- D. Data breach
Answer: D
Explanation:
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.
NEW QUESTION # 14
During analysis, the Dell Services team found outdated applications and operating systems with missing security patches. To avert potential cyberattacks, Dell recommends application and operating system hardening measures.
Why is security hardening important for A.R.T.I.E .?
- A. Decrease attack surface.
- B. Enhance productivity.
- C. Enhance operational cost.
- D. Remove redundancy.
Answer: A
Explanation:
* Security Hardening Definition:Security hardening involves implementing measures to reduce vulnerabilities in applications and operating systems1.
* Reducing Attack Surface:By updating and patching outdated applications and operating systems,A
.R.T.I.E.can minimize the number of potential entry points for attackers1.
* Preventing Cyberattacks:Hardening is a proactive measure to protect against potential cyberattacks by eliminating as many security risks as possible1.
* Compliance with Best Practices:Security hardening aligns with industry best practices and regulatory requirements, which is essential forA .R.T.I.E.'s operations in the public cloud1.
* Dell's Recommendation:Dell's Security Foundations Achievement emphasizes the importance of security hardening as a fundamental aspect of an organization's cybersecurity strategy1.
Security hardening is crucial forA .R.T.I.E.because it directly contributes to the robustness of their cybersecurity posture, ensuring that their systems are less susceptible to attacks and breaches1.
NEW QUESTION # 15
A .R.T.I.E.has an evolving need, which was amplified during the incidents. Their complex and dispersed IT environments have thousands of users, applications, and resources to manage. Dell found that the existing Identity and Access Management was limited in its ability to apply expanding IAM protection to applications beyond the core financial and human resource management application.A .R.T.I.E.also did not have many options for protecting their access especially in the cloud.A .R.T.I.E.were also not comfortable exposing their applications for remote access.
Dell recommended adopting robust IAM techniques like mapping out connections between privileged users and admin accounts, and the use multifactor authentication.
The Dell Services team suggest implementing a system that requires individuals to provide a PIN and biometric information to access their device.
Which type of multifactor authentication should be suggested?
- A. Something you have and something you are.
- B. Something you know and something you are.
- C. Something you have and something you know.
Answer: A
Explanation:
The recommended multifactor authentication (MFA) type forA .R.T.I.E., as suggested by Dell Services, isA.
Something you have and something you are. This type of MFA requires two distinct forms of identification:
one that the user possesses (something you have) and one that is inherent to the user (something you are).
* Something you havecould be a physical token, a security key, or a mobile device that generates time-based one-time passwords (TOTPs).
* Something you arerefers to biometric identifiers, such as fingerprints, facial recognition, or iris scans, which are unique to each individual.
By combining these two factors, the authentication process becomes significantly more secure than using any single factor alone. The physical token or device provides proof of possession, which is difficult for an attacker to replicate, especially without physical access. The biometric identifier ensures that even if the physical token is stolen, it cannot be used without the matching biometric input.
References:
* The use of MFA is supported by security best practices and standards, including those outlined by the National Institute of Standards and Technology (NIST).
* Dell's own security framework likely aligns with these standards, advocating for robust authentication mechanisms to protect against unauthorized access, especially in cloud environments where the attack surface is broader.
In the context ofA .R.T.I.E.'s case, where employees access sensitive applications and data remotely, implementing MFA with these two factors will help mitigate the risk of unauthorized access and potential data breaches. It is a proactive step towards enhancing the organization's security posture in line with Dell's strategic advice.

In the cloud, there are numerous configuration options for the services provided. If not properly set, these configurations can leave the environment in an unsecure state where an attacker can read and modify the transmitted data packets and send their own requests to the client.
Which types of attack enable an attacker to read and modify the transmitted data packets and send their own requests to the client?
- A. Data loss
- B. Shared technology
- C. TCP hijacking
- D. Dumpster diving
Answer: C
Explanation:
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.
NEW QUESTION # 18
AR.T.I.E.'s business is forecast to grow tremendously in the next year, the organization will not only need to hire new employees but also requires contracting with third-party vendors to continue seamless operations.A
.R.T.I.E.uses a VPN to support its employees on the corporate network, but the organization is facing a security challenge in supporting the third-party business vendors.
To better meetA .R.T.I.E.'s security needs, the cybersecurity team suggested adopting a Zero Trust architecture (ZTA). The main aim was to move defenses from static, network-based perimeters to focus on users, assets, and resources. Zero Trust continuously ensures that a user is authentic and the request for resources is also valid. ZTA also helps to secure the attack surface while supporting vendor access.
What is the main challenge that ZTA addresses?
- A. Authorization ofA .R.T.I.E.employees.
- B. Access to the corporate network for third-party vendors.
- C. Proactive defense in-depth strategy.
- D. Malware attacks.
Answer: B
Explanation:
The main challenge that Zero Trust Architecture (ZTA) addresses is the access to the corporate network for third-party vendors.ZTA is a security model that assumes no implicit trust is granted to assets or user accounts based solely on their physical or network location (i.e., local area networks versus the internet) or based on asset ownership (enterprise or personallyowned)12. It mandates that any attempt to access resources be authenticated and authorized within a dynamic policy context.
A .R.T.I.E.'s business model involves contracting with third-party vendors to continue seamless operations, which presents a security challenge.The traditional VPN-based approach to network security is not sufficient for this scenario because it does not provide granular control over user access and does not verify the trustworthiness of devices and users continuously2.
Implementing ZTA would address this challenge by:
* Ensuring that all users, even those within the network perimeter, must be authenticated and authorized to access any corporate resources.
* Providing continuous validation of the security posture of both the user and the device before granting access to resources.
* Enabling the organization to apply more granular security controls, which is particularly important when dealing with third-party vendors who require access to certain parts of the network31.
This approach aligns with the case study's emphasis on securing the attack surface while supporting vendor access, as it allowsA .R.T.I.E.to grant access based on the principle of least privilege, reducing the risk of unauthorized access to sensitive data and systems4.
