Question No. 1

A .R.T.I.E. is planning to deploy some of their applications in a public cloud. A major concern is how to share and protect data off premises. Also, how data can be used in decision making without exposing it to anyone who should not have access. Dell Services briefed them about various control mechanisms to secure data in the public cloud.

Which control mechanism should be selected in this scenario?

AProactive control mechanism

BDetective control mechanism

CCorrective control mechanism

Show Answer

Correct Answer: A

Control Mechanism Selection:

For A .R.T.I.E.'s scenario, where the concern is about sharing and protecting data off-premises and ensuring that data can be used in decision-making without exposing it to unauthorized access, the most suitable control mechanism would be:

A . Proactive control mechanism

Proactive control mechanisms are designed to prevent security incidents before they occur. They include measures such as strong authentication, encryption, and access controls, which align with A .R.T.I.E.'s requirements for secure migration to the public cloud and maintaining data confidentiality during decision-making processes1234.

Data Encryption: Encrypting data at rest and in transit ensures that even if data is intercepted or accessed by unauthorized individuals, it remains unreadable and secure2.

Access Control: Implementing robust access control measures, such as role-based access control (RBAC) and multi-factor authentication (MFA), restricts data access to authorized personnel only34.

Firewalls and Network Security: Deploying firewalls and other network security measures helps to protect the cloud environment from unauthorized access and potential breaches2.

Security Monitoring: Continuous monitoring of the cloud environment allows for the early detection of potential security threats and vulnerabilities2.

Security Patching and Upgrades: Regularly updating and patching systems ensures that security measures are up-to-date and can defend against the latest threats2.

These proactive controls are essential for A .R.T.I.E. as they provide a comprehensive approach to securing data in the public cloud, align with the Dell Security Foundations Achievement's focus on security hardening, and support the Zero Trust model, which assumes no implicit trust and verifies each request as though it originates from an open network5.

Question No. 2

Which framework should be recommended to A .R.T.I.E. to enhance the overall security and resilience of their critical infrastructure, and outline methods to reduce their cybersecurity risk?

ANIST CSF

BCOBIT

CPCIDSS

DHIPAA

Show Answer

Correct Answer: A

Based on the case study provided and the requirements for A .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

The NIST Cybersecurity Framework (CSF) is recommended for A .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 with A .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 for A .R.T.I.E.'s open platform nature1.

Question No. 3

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?

AData loss

BShared technology

CTCP hijacking

DDumpster diving

Show Answer

Correct Answer: C

Verified Answer: The type of attack that enables an attacker to read and modify the transmitted data packets and send their own requests to the client is:

C . TCP hijacking

TCP Hijacking Definition: TCP hijacking is a type of cyber attack where an attacker takes control of a communication session between two entities12.

Attack Mechanism: The attacker intercepts and manipulates data packets being sent over the network, allowing them to read, modify, and insert their own packets into the communication stream1.

Impact on Security: This attack can lead to unauthorized access to sensitive data and systems, and it can be used to impersonate the victim, resulting in data breaches and other security incidents1.

Prevention Measures: Implementing security measures such as encryption, using secure protocols, and monitoring network traffic can help prevent TCP hijacking attacks1.

TCP hijacking is particularly relevant to cloud environments where misconfigurations can leave systems vulnerable. It is crucial for A .R.T.I.E. to ensure proper security configurations and adopt measures to protect against such attacks as part of their migration to the public cloud and overall cybersecurity strategy12.

Question No. 4

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?

ACryptolocker

BDouble extortion

CCrypto

DLocker

Show Answer

Correct Answer: B

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.
