DRAG DROP Dell Services team cannot eliminate all risks, but they can continually evaluate the resilience and preparedness of A .R.T.I.E. by using the National Institute of Standards and Technology Cybersecurity Framework (NIST CSF). Match the core NIST CSF component functions with the description that the Dell Services team would have recommended to A .R.T.I.E.
To minimize the cost and damage of ransomware attacks the cybersecurity team provided static analysis of files in an environment and compare a ransomware sample hash to known data. Which detection mechanism is used to detect data theft techniques to access valuable information and hold ransom?
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 .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?
Based on the information in the case study, which security team should be the most suitable to perform root cause analysis of the attack and present the proposal to solve the challenges faced by the A .R.T.I.E. organization?
An A .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?
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 of A .R.T.I.E. The monitored entities include A .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?
During the analysis, the threat intelligence team disclosed that attackers not only encrypted files, but also attempted to encrypt backups and shared, networked, and cloud drives. Which type of ransomware is used for this attack?
During the analysis, the threat intelligence team disclosed a possible threat which went unnoticed when an A .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?
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 risk A .R.T.I.E. is primarily exposed?

Question 9 - D-SF-A-24 discussion

Report
Export

A R.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 meet A .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?

D.
Proactive defense in-depth strategy.
Suggested answer: C

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 personally owned)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 allows A .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.
