CSC - Cybersecurity Compliance Cloud Security Compliance Questions and Answers 1 — Questions and Answers
Question 1: A company deploys a custom application on virtual machines within an Infrastructure as a Service (IaaS) cloud environment. A critical vulnerability is discovered in the operating system of these virtual machines. According to the shared responsibility model, who is primarily responsible for patching the operating system vulnerability?
- The cloud service provider (CSP), as they manage the underlying infrastructure.
- The customer, as they control the guest operating system and applications. (Correct answer)
- The operating system vendor, who is solely responsible for issuing patches.
- Both the CSP and the customer, who must coordinate the patching process together.
Correct answer: The customer, as they control the guest operating system and applications.
In the IaaS model, the CSP is responsible for the security *of* the cloud (physical infrastructure, network, hypervisor), while the customer is responsible for security *in* the cloud. This includes securing and patching the guest operating system, managing applications, and protecting data.
Question 2: A U.S. federal agency needs to procure a cloud service to store and process highly sensitive, unclassified data, where a breach could have a severe or catastrophic adverse effect on agency operations or assets. Which FedRAMP impact level is MOST appropriate for this cloud service?
- FedRAMP Low
- FedRAMP Moderate
- FedRAMP High (Correct answer)
- FedRAMP Ready
Correct answer: FedRAMP High
FedRAMP High is specifically designed for the government's most sensitive, unclassified data in cloud environments. This level is appropriate for systems where the loss of confidentiality, integrity, or availability could cause severe or catastrophic harm to organizational operations, assets, or individuals.
Question 3: An organization is evaluating several cloud service providers and wants to use a standardized framework to assess their security controls against industry best practices. Which Cloud Security Alliance (CSA) tool provides a comprehensive matrix of cloud-specific controls mapped to major standards and regulations?
- The Cloud Controls Matrix (CCM) (Correct answer)
- The Consensus Assessments Initiative Questionnaire (CAIQ)
- The STAR (Security, Trust, Assurance, and Risk) Registry
- The Top Threats to Cloud Computing Report
Correct answer: The Cloud Controls Matrix (CCM)
The CSA Cloud Controls Matrix (CCM) is a cybersecurity control framework specifically for cloud computing. It provides a detailed list of security controls and maps them to other major frameworks like ISO 27001, NIST SP 800-53, and PCI DSS, serving as a tool for systematic assessment of a cloud provider's security posture.
Question 4: A European company is using a global SaaS provider for its HR platform, which processes employee data subject to GDPR. Which of the following is the MOST effective control for addressing data sovereignty requirements?
- Implementing multi-factor authentication for all platform users.
- Ensuring the SaaS provider has a current SOC 2 Type 2 attestation.
- Encrypting all data at rest and in transit using industry-standard algorithms.
- Contractually requiring and technically configuring the service to process and store all data within a specific EU data center region. (Correct answer)
Correct answer: Contractually requiring and technically configuring the service to process and store all data within a specific EU data center region.
Data sovereignty laws, like those under GDPR, require personal data to be governed by the laws of a specific jurisdiction. The most direct way to comply is to ensure the data physically resides within that jurisdiction (e.g., the EU). This is achieved through contractual agreements and technical configurations that restrict data storage and processing to designated regions.
Question 5: A retail company is building its e-commerce platform in a public cloud and must maintain PCI DSS compliance. Even if the company uses a PCI-compliant IaaS provider, which of the following security tasks remains the company's direct responsibility?
- Disposing of physical hard drives from decommissioned servers.
- Securing the physical data center facilities against unauthorized access.
- Configuring virtual network firewalls (security groups) to restrict traffic to the Cardholder Data Environment (CDE). (Correct answer)
- Managing the hypervisor that hosts the company's virtual machines.
Correct answer: Configuring virtual network firewalls (security groups) to restrict traffic to the Cardholder Data Environment (CDE).
According to the shared responsibility model for PCI DSS in an IaaS cloud, the provider handles physical security and the underlying infrastructure, including the hypervisor. The customer, however, is responsible for everything they build on top of that infrastructure, including configuring their virtual network, securing their operating systems, and implementing access controls like virtual firewalls (security groups) to protect the CDE.
Question 6: A medical software company uses a cloud service provider (CSP) to store and process electronic Protected Health Information (ePHI). What is the essential legal agreement required by HIPAA that must be executed between the company and the CSP?
- A Master Service Agreement (MSA)
- A Non-Disclosure Agreement (NDA)
- A Service Level Agreement (SLA)
- A Business Associate Agreement (BAA) (Correct answer)
Correct answer: A Business Associate Agreement (BAA)
The HIPAA Security and Privacy Rules require a covered entity (the medical software company) to have a signed Business Associate Agreement (BAA) with any business associate (the CSP) that handles ePHI on its behalf. The BAA establishes the CSP's legal responsibility to safeguard the ePHI according to HIPAA standards.
