NEW QUESTION # 10
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?
- A. Locker
- B. Double extortion
- C. Crypto
- D. Cryptolocker
Answer: B
Explanation:
* Double Extortion Ransomware:This type of ransomware not only encrypts files but also attempts to encrypt backups and shared, networked, and cloud drives1.
* Attack Method:Attackers first exfiltrate sensitive data before encrypting it, then threaten to release the data if the ransom is not paid, hence the term 'double extortion'1.
* Impact on Organizations:This method increases the pressure on the victim to pay the ransom, as they face the risk of their sensitive data being published or sold1.
* Prevention and Response:Organizations should implement robust backup strategies, including offsite and offline backups, and have an incident response plan that includes dealing with ransomware and data breaches1.
Double extortion ransomware attacks are particularly dangerous because they combine the threat of data encryption with the threat of data exposure, significantly increasing the potential damage to the victim organization1.

NEW QUESTION # 14
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 know and something you are.
- B. Something you have and something you know.
- C. Something you have and something you are.
Answer: C
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.

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
. Commonly known as the core security team which has a global presence.
. Helps organizations to evaluate and gauge their exposure to cybersecurity risk.
. Supports various organizations in developing a vision and strategy for handling cyberattacks.
. Provides advice on the implementation of standard cybersecurity frameworks.
Ethical hackers
. Works within the defined boundaries to legally infiltrate the organization's network environment with their permission.
. Exposes vulnerabilities in customers IT systems.
Threat intelligence and incident management team
. The team help to keep the organization apprised of the latest developments in the security landscape.
. The cyber security intelligence team investigates methodologies and technologies to help organizations detect, understand, and deflect advanced cybersecurity threats and attacks on their IT infrastructure, and in the cloud.
. The incident management team helps consider what they would do when under attack. The team may simulate an attack to ensure that non-technical staff members know how to respond.
. The simulated attack is managed by the incident management team. This team also helps to prevent future attacks based on the information gathered.
Identity and Access Management team
. Reviews and accesses the access rights for each member and user.
. During their analysis the Dell cyber team did a thorough analysis to help create a secure environment for A.R.T.I.E.and mitigate potential attacks.
Outcomes
With the rapid and thorough analysis of security events originating from both internal and external sources to A.R.T.I.E.complete, the Dell Services team could detect anomalies, uncover advanced threats and remove false positives. The Threat Intelligence team was also able to provide a list of potentially malicious IP addresses, malware, and threat actors.
Along with this, the team also implemented methods that helped determine what is being attacked and how to stop an attack providingA .R.T.I.E.with real time threat detection mechanisms, knowledge on cyber security.
The common outcomes after implementation of the Dell recommendations were:
. Prioritization of threat and impact - Determine threat intelligence, vulnerability status and network communications to evaluate accurate vulnerability risk.
. Secure workforce and educate employees about best practices to be adopted to mitigate attacks, security frameworks and policies.
. Implementation of incident management plan and build an organization-wide security strategy to avert future attacks.
. Identification of at-risk users and authorized users, account takeover, disgruntled employees, malware actions.
. Streamlining of security solutions while reducing operational costs and staffing requirements.
. Increased effectiveness to address the continual growth of IT environments, along with the sharp rise in the number of threats and attacks.
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 # 16
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. Proactive defense in-depth strategy.
- B. Authorization ofA .R.T.I.E.employees.
- C. Malware attacks.
- D. Access to the corporate network for third-party vendors.
Answer: D
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.
NEW QUESTION # 17
Match the security hardening type with the hardening techniques.
Answer:
Explanation:
Explanation:
The security hardening techniques should be matched with the corresponding source area as follows:
* Operating System:Enables secure boot and removes unnecessary drivers.
* Database:Implements Role-Based Access Control and removes unnecessary database services.
* Network:Implements Intrusion Prevention System.
* Server:Encrypts the host device using hardware trusted privilege.
* Operating System Hardening:Involves enabling secure boot to ensure that only trusted software is loaded during the system startup and removing unnecessary drivers to minimize potential vulnerabilities1.
* Database Hardening:Role-Based Access Control (RBAC) restricts system access to authorized users, and removing unnecessary services reduces the attack surface1.
* Network Hardening:An Intrusion Prevention System (IPS) monitors network traffic for suspicious activity and takes action to prevent intrusions1.
* Server Hardening:Encrypting the host device using hardware-based mechanisms like Trusted Platform Module (TPM) provides a secure environment for the server's operating system1.
These matches are based on standard security practices that align with the Dell Security Foundations Achievement's emphasis on security hardening across different areas of IT infrastructure1.
