What is the primary responsibility of a cloud service provider (CSP) in terms of cloud security?

  1. Ensuring the physical security of customer data and infrastructure

  2. Providing comprehensive security controls and measures to protect customer data

  3. Implementing and managing security policies for customer applications

  4. Educating customers on cloud security best practices


Correct Option: B
Explanation:

The primary responsibility of a CSP is to provide comprehensive security controls and measures to protect customer data, ensuring the confidentiality, integrity, and availability of information stored and processed in the cloud.

Which of the following is NOT a common type of cloud computing security threat?

  1. Distributed Denial of Service (DDoS) attacks

  2. Malware and virus infections

  3. Data breaches and unauthorized access

  4. Physical security breaches


Correct Option: D
Explanation:

Physical security breaches are not typically associated with cloud computing security threats, as cloud infrastructure is managed and secured by the CSP in a remote and controlled environment.

What is the primary benefit of implementing multi-factor authentication (MFA) in cloud computing?

  1. Enhancing the security of user accounts and preventing unauthorized access

  2. Improving the performance and scalability of cloud applications

  3. Reducing the cost of cloud computing services

  4. Simplifying the management of cloud resources


Correct Option: A
Explanation:

MFA adds an extra layer of security by requiring users to provide multiple forms of identification, such as a password and a one-time code, to access cloud resources, making it more difficult for attackers to compromise user accounts.

Which cloud computing security best practice involves regularly backing up and storing data in multiple locations?

  1. Data encryption

  2. Multi-factor authentication

  3. Data backup and recovery

  4. Least privilege principle


Correct Option: C
Explanation:

Data backup and recovery involves creating regular backups of data and storing them in multiple locations to ensure that data can be restored in case of data loss or corruption.

What is the purpose of implementing a least privilege principle in cloud computing security?

  1. To restrict user access to only the resources and data they need to perform their job

  2. To enhance the performance and scalability of cloud applications

  3. To reduce the cost of cloud computing services

  4. To simplify the management of cloud resources


Correct Option: A
Explanation:

The least privilege principle involves granting users only the minimum level of access necessary to perform their job duties, reducing the risk of unauthorized access and data breaches.

Which of the following is a common cloud computing security standard that organizations can adopt?

  1. ISO 27001

  2. PCI DSS

  3. HIPAA

  4. NIST 800-53


Correct Option: A
Explanation:

ISO 27001 is a widely recognized international standard that provides a framework for implementing and managing an information security management system (ISMS) in organizations, including cloud computing environments.

What is the primary goal of implementing a cloud security posture management (CSPM) tool?

  1. To continuously monitor and assess the security posture of cloud resources

  2. To improve the performance and scalability of cloud applications

  3. To reduce the cost of cloud computing services

  4. To simplify the management of cloud resources


Correct Option: A
Explanation:

CSPM tools are designed to continuously monitor and assess the security posture of cloud resources, identifying security risks and vulnerabilities, and providing recommendations for improvement.

Which of the following is a common cloud computing security threat that involves exploiting vulnerabilities in web applications?

  1. Cross-site scripting (XSS)

  2. Distributed Denial of Service (DDoS) attacks

  3. Malware and virus infections

  4. Data breaches and unauthorized access


Correct Option: A
Explanation:

Cross-site scripting (XSS) is a common cloud computing security threat that involves injecting malicious code into web applications, allowing attackers to steal sensitive information or compromise user accounts.

What is the purpose of implementing a zero-trust security model in cloud computing?

  1. To assume that all users and devices are untrusted and require verification before granting access

  2. To enhance the performance and scalability of cloud applications

  3. To reduce the cost of cloud computing services

  4. To simplify the management of cloud resources


Correct Option: A
Explanation:

A zero-trust security model assumes that all users and devices are untrusted and require verification before granting access to cloud resources, reducing the risk of unauthorized access and data breaches.

Which of the following is a common cloud computing security threat that involves gaining unauthorized access to sensitive data?

  1. Data breaches and unauthorized access

  2. Distributed Denial of Service (DDoS) attacks

  3. Malware and virus infections

  4. Cross-site scripting (XSS)


Correct Option: A
Explanation:

Data breaches and unauthorized access involve gaining unauthorized access to sensitive data stored in cloud systems, often through vulnerabilities or weak security controls.

What is the purpose of implementing a cloud access security broker (CASB) in cloud computing?

  1. To control and monitor access to cloud resources and enforce security policies

  2. To enhance the performance and scalability of cloud applications

  3. To reduce the cost of cloud computing services

  4. To simplify the management of cloud resources


Correct Option: A
Explanation:

A CASB is a cloud-based security solution that controls and monitors access to cloud resources, enforces security policies, and provides visibility and control over cloud usage.

Which of the following is a common cloud computing security threat that involves disrupting the availability of cloud services?

  1. Distributed Denial of Service (DDoS) attacks

  2. Malware and virus infections

  3. Data breaches and unauthorized access

  4. Cross-site scripting (XSS)


Correct Option: A
Explanation:

DDoS attacks involve flooding cloud services with大量of traffic, overwhelming their resources and making them unavailable to legitimate users.

What is the purpose of implementing a security information and event management (SIEM) system in cloud computing?

  1. To collect, analyze, and respond to security events and alerts

  2. To enhance the performance and scalability of cloud applications

  3. To reduce the cost of cloud computing services

  4. To simplify the management of cloud resources


Correct Option: A
Explanation:

A SIEM system collects, analyzes, and responds to security events and alerts generated by cloud resources, providing centralized visibility and control over security incidents.

Which of the following is a common cloud computing security threat that involves exploiting vulnerabilities in cloud infrastructure?

  1. Infrastructure-as-a-Service (IaaS) vulnerabilities

  2. Malware and virus infections

  3. Data breaches and unauthorized access

  4. Cross-site scripting (XSS)


Correct Option: A
Explanation:

IaaS vulnerabilities involve exploiting weaknesses in the underlying cloud infrastructure, such as hypervisors, virtual machines, and storage systems, to gain unauthorized access or compromise cloud resources.

What is the purpose of implementing a cloud security assessment framework in cloud computing?

  1. To evaluate the security posture of cloud resources and identify areas for improvement

  2. To enhance the performance and scalability of cloud applications

  3. To reduce the cost of cloud computing services

  4. To simplify the management of cloud resources
