EMC D-SF-A-24 Dumps Questions Answers

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.

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.

Based on the case study provided and the requirements forA .R.T.I.E., the most suitable framework to enhance the overall security and resilience of their critical infrastructure, and to outline methods to reduce their cybersecurity risk would be:

A. NIST CSF

TheNIST Cybersecurity Framework (CSF)is recommended forA .R.T.I.E.to enhance security and resilience.The NIST CSF provides guidelines for organizations to manage cybersecurity risks in a structured and prioritized manner12.

Identify:A .R.T.I.E.can use the NIST CSF to identify its digital assets, cybersecurity policies, and the current threat landscape1.

Protect:Implement protective technology to ensure that critical infrastructure services are not disrupted1.

Detect:Use the framework to implement advanced detection processes to quickly identify cybersecurity events1.

Respond:Develop and implement appropriate activities to take action regarding a detected cybersecurity incident1.

Recover:Plan for resilience and to restore any capabilities or services that were impaired due to a cybersecurity incident1.

The NIST CSF aligns withA .R.T.I.E.'s need for a secure migration to the public cloud and addresses the need for a holistic security capability that ensures security across the organization2.It also supports the Zero Trust model, which is crucial forA .R.T.I.E.'s open platform nature1.

Based on the Dell Security Foundations Achievement and the NIST Cybersecurity Framework (CSF), the core NIST CSF component functions can be matched with the descriptions as follows:

Identify:Cultivate the organizational understanding of cybersecurity risks.

Protect:Plan and implement appropriate safeguards.

Detect:Develop ways to identify cybersecurity breaches.

Respond:Quickly mitigate damage if a cybersecurity incident is detected.

Recover:Restore capabilities that were impaired due to a cyberattack12345.

Identify Function:Involves understanding the business context, the resources that support critical functions, and the related cybersecurity risks3.

Protect Function:Includes the appropriate safeguards to ensure delivery of critical infrastructure services4.

Detect Function:Defines the appropriate activities to identify the occurrence of a cybersecurity event4.

Respond Function:Includes the appropriate activities to take action regarding a detected cybersecurity event4.

Recover Function:Identifies appropriate activities to maintain plans for resilience and to restore any capabilities or services that were impaired due to a cybersecurity event4.

These functions are integral to the NIST CSF and provide a high-level strategic view of the lifecycle of an organization’s management of cybersecurity risk12345.The Dell Security Foundations Achievement documents would likely align with these functions, emphasizing their importance in a comprehensive cybersecurity strategy12.
