質問 # 128
The tech giant TSC uses cloud for its operations. As a cloud user, it should implement an effective risk management lifecycle to measure and monitor high and critical risks regularly. Additionally, TSC should define what exactly should be measured and the acceptable variance to ensure timely mitigated risks. In this case, which of the following can be used as a tool for cloud risk management?
正解：D
解説：
The CSA CCM (Cloud Controls Matrix) Framework is a cybersecurity control framework for cloud computing, developed by the Cloud Security Alliance (CSA). It is designed to provide a structured and standardized set of security controls that help organizations assess the overall security posture of their cloud infrastructure and services.
Here's how the CSA CCM Framework serves as a tool for cloud risk management:
Comprehensive Controls: The CCM consists of 197 control objectives structured in 17 domains covering all key aspects of cloud technology.
Risk Assessment: It can be used for the systematic assessment of a cloud implementation, providing guidance on which security controls should be implemented.
Alignment with Standards: The controls framework is aligned with the CSA Security Guidance for Cloud Computing and other industry-accepted security standards and regulations.
Shared Responsibility Model: The CCM clarifies the shared responsibility model between cloud service providers (CSPs) and customers (CSCs).
Monitoring and Measurement: The CCM includes metrics and implementation guidelines that help define what should be measured and the acceptable variance for risks.
Reference:
CSA's official documentation on the Cloud Controls Matrix (CCM), which outlines its use as a tool for cloud risk management1.

Bruce McFee works as a cloud security engineer in an IT company. His organization uses AWS cloud-based services. Because Amazon CloudFront offers low-latency and high-speed data delivery through a user-friendly environment, Bruce's organization uses the CloudFront content delivery network (CDN) web service for the fast and secure distribution of data to various customers throughout the world. How does CloudFront accelerate content distribution?
正解：D
解説：
Explore
Content Delivery Network (CDN): Amazon CloudFront is a CDN that accelerates the delivery of content by caching it at edge locations that are closer to the end-users1.
Edge Locations: These are data centers located around the world that store cached copies of content so that it can be delivered more quickly to users1.
Low Latency: When a user requests content, DNS routes the request to the CloudFront Point of Presence (POP) that can best serve the request, typically the nearest CloudFront POP in terms of latency1.
Cache Check: CloudFront checks its cache for the requested object. If the object is in the cache, CloudFront returns it to the user1.
Cache Miss: If the object is not in the cache, CloudFront forwards the request to the origin server for the object, and then the origin server sends the object back to the edge location. As soon as the first byte arrives from the origin, CloudFront begins to forward the object to the user and adds it to the cache for the next time someone requests it1.
Reference:
Amazon's official documentation on how CloudFront delivers content1.

Chris Evans has been working as a cloud security engineer in a multinational company over the past 3 years. His organization has been using cloud-based services. Chris uses key vault as a key management solution because it offers easier creation of encryption keys and control over them. Which of the following public cloud service providers allows Chris to do so?
正解：C
解説：
Azure Key Vault is a cloud service provided by Microsoft Azure. It is used for managing cryptographic keys and other secrets used in cloud applications and services. Chris Evans, as a cloud security engineer, would use Azure Key Vault for the following reasons:
Key Management: Azure Key Vault allows for the creation and control of encryption keys used to encrypt data.
Secrets Management: It can also manage other secrets such as tokens, passwords, certificates, and API keys.
Access Control: Key Vault provides secure access to keys and secrets based on Azure Active Directory identities.
Audit Logs: It offers monitoring and logging capabilities to track how and when keys and secrets are accessed.
Integration: Key Vault integrates with other Azure services, providing a seamless experience for securing application secrets.
Reference:
Azure's official documentation on Key Vault, which outlines its capabilities for key management and security.

Cindy Williams has been working as a cloud security engineer in an IT company situated in Austin, Texas.
Owing to the robust security and cost-effective features provided by AWS, her organization adopted AWS cloud-based services. Cindy has deployed an application in the Amazon Elastic Compute Cloud (EC2) instance.
Which of the following cloud computing service model does the Amazon EC2 instance represent?
正解：D
解説：
Amazon Elastic Compute Cloud
Amazon Elastic Compute Cloud
Explore
* Cloud Service Models: There are three primary cloud service models, which are Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS)1.
* Amazon EC2: Amazon Elastic Compute Cloud (Amazon EC2) is a web service that provides secure, resizable compute capacity in the cloud. It allows users to run virtual servers and manage storage, security, and networking1.
* IaaS Definition: IaaS provides virtualized computing resources over the internet. In an IaaS model, a cloud provider hosts the infrastructure components traditionally present in an on-premises data center, including servers, storage, and networking hardware1.
* EC2 as IaaS: Amazon EC2 falls under the IaaS category because it provides the hardware infrastructure, allows users to scale computing capacity up or down, and users pay only for the capacity they use1.
* Exclusion of Other Models: EC2 is not PaaS because it does not provide a platform for developing, running, or managing applications. It's not SaaS as it doesn't deliver software over the internet. DaaS, or Desktop as a Service, provides virtual desktops, which is not the service EC2 offers1.

VenturiaCloud is a cloud service provider that offers robust and cost-effective cloud-based services to cloud consumers. The organization became a victim of a cybersecurity attack. An attacker performed a DDoS attack over the cloud that caused failure in the entire cloud environment. VenturiaCloud conducted a forensics investigation. Who among the following are the first line of defense against cloud security attacks with their primary role being responding against any type of security incident immediately?
正解：C
解説：
Incident Handlers are typically the first line of defense against cloud security attacks, with their primary role being to respond immediately to any type of security incident. In the context of a cybersecurity attack such as a DDoS (Distributed Denial of Service), incident handlers are responsible for the initial response, which includes identifying, managing, recording, and analyzing security threats or incidents in real-time.
Here's how Incident Handlers function as the first line of defense:
Immediate Response: They are trained to respond quickly to security incidents to minimize impact and manage the situation.
Incident Analysis: Incident Handlers analyze the nature and scope of the incident, including the type of attack and its origin.
Mitigation Strategies: They implement strategies to mitigate the attack, such as rerouting traffic or isolating affected systems.
Communication: They communicate with relevant stakeholders, including IT professionals, management, and possibly law enforcement.
Forensics and Recovery: After an attack, they work on forensics to understand how the breach occurred and on recovery processes to restore services.
Reference:
An ISACA journal article discussing the roles of various functions in information security, highlighting the first line of defense1.
An Australian Cyber Security Magazine article emphasizing the importance of identity and access management (IAM) as the first line of defense in securing the cloud2.
