最新的 Dell Security D-SF-A-24 免費考試真題 (Q14-Q19):

問題 #14
An externalA .R.T.I.E.user requires access to sensitive resources and data.
Which authentication technique should be best recommended to provide access to this business user?

A. Single Sign-On
B. Two-factor
C. Multifactor
D. Privileged Access Management

答案：C

解題說明：
* Multifactor Authentication (MFA) Definition:MFA requires users to provide multiple forms of identification before gaining access to a resource1.
* Security Enhancement:MFA enhances security by combining something the user knows (like a password), something the user has (like a smartphone), and something the user is (like a fingerprint)1.
* Protection Against Unauthorized Access:This method protects against unauthorized access by ensuring that even if one factor (like a password) is compromised, the attacker still needs the other factors to gain access1.
* Compliance with Regulations:MFA helps organizations comply with various regulations and cloud security controls, which is essential forA .R.T.I.E.as they move to the public cloud1.
* Dell's Commitment to MFA:Dell's own security guidelines emphasize the importance of MFA, reflecting their commitment to safeguarding data integrity and providing an additional layer of security during the sign-in process1.
MFA is particularly suitable forA .R.T.I.E.'s scenario because it provides robust security for accessing sensitive resources and data, which is crucial for external users who may not be within the secure internal network1.

問題 #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 know.
B. Something you know and something you are.
C. Something you have and something you are.

答案：C

解題說明：
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.

問題 #16
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. Internet of Things risk
B. Data risk
C. Hardware risk
D. Protection risk

答案：B

解題說明：
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!

問題 #17
AnA .R.T.I.E.employee received an email with an invoice that looks official for $200 for a one-year subscription. It clearly states: "Please do not reply to this email," but provides a Help and Contact button along with a phone number.
What is the type of risk if the employee clicks the Help and Contact button?

A. Technology
B. People
C. Strategic
D. Operational

答案：B

解題說明：
* People Risk Definition:People risk involves the potential for human error or intentional actions that can lead to security incidents1.
* Phishing and Social Engineering:The scenario described is typical of phishing, where attackers use seemingly official communications to trick individuals into revealing sensitive information or accessing malicious links1.
* Employee Actions:Clicking on the button could potentially lead to the employee inadvertently providing access to the company's systems or revealing personal or company information1.
* Dell's Security Foundations Achievement:Dell's Security Foundations Achievement emphasizes the importance of recognizing and minimizing phishing exploits as part of managing people risk21.
* Mitigation Measures:Training employees to recognize and respond appropriately to phishing attempts is a key strategy in mitigating people risk1.
In this context, the risk is categorized as 'people' because it directly involves the potential actions of an individual employee that could compromise security1.

問題 #18
The security team recommends the use of User Entity and Behavior Analytics (UEBA) in order to monitor and detect unusual traffic patterns, unauthorized data access, and malicious activity ofA .R.T.I.E.The monitored entities includeA .R.T.I.E.processes, applications, and network devices Besides the use of UEBA, the security team suggests a customized and thorough implementation plan for the organization.
What are the key attributes that define UEBA?

A. User analytics, encryption, and data.
B. User analytics, threat detection, and data.
C. Encryption, automation, and data.
D. Automation, user analytics, and data.

答案：B

解題說明：
* User Analytics:UEBA systems analyze user behavior to establish a baseline of normal activities and detect anomalies12.
* Threat Detection:By monitoring for deviations from the baseline, UEBA can detect potential security threats, such as compromised accounts or insider threats12.
* Data Analysis:UEBA solutions ingest and analyze large volumes of data from various sources within the organization to identify suspicious activities12.
* Behavioral Analytics:UEBA uses behavioral analytics to understand how users typically interact with the organization's systems and data12.
* Machine Learning and Automation:Advanced machine learning algorithms and automation are employed to refine the analysis and improve the accuracy of anomaly detection over time12.
UEBA is essential forA .R.T.I.E.as it provides a comprehensive approach to security monitoring, which is critical given the diverse and dynamic nature of their user base and the complexity of their IT environment12.
