NEW QUESTION # 14
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!

NEW QUESTION # 18
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.
