Free Practice Questions for Cloud Security Alliance CCSK Exam

The principle of Segregation of Duties (SoD) focuses on implementing multiple security layers by dividing responsibilities among different individuals or systems to ensure that no single entity has enough control to misuse or compromise access. This principle helps to prevent fraud, error, and misuse by ensuring that critical tasks are divided and that sensitive actions require multiple people or processes to perform, adding an extra layer of security.

Continuous Monitoring refers to the ongoing observation of activities to detect unusual behavior, but it is not directly about diluting access power. Federation involves linking multiple identity management systems together to allow access across different domains but does not specifically address limiting access power through multiple security layers. Principle of Least Privilege ensures that users have only the minimum necessary access to perform their tasks, but it does not directly involve dividing duties or responsibilities.

Cloud Detection and Response (CDR) is an emerging capability that focuses specifically on detecting and responding to threats in cloud environments. While not deeply detailed in the core CSA Security Guidance v4.0, CDR is an evolution of traditional SIEM and endpoint detection strategies applied to cloud-native infrastructures.

In CSA Security Guidance v4.0 – Domain 9: Incident Response, it’s made clear that:

“Security monitoring and detection capabilities in the cloud must be able to identify suspicious behavior, policy violations, and misconfigurations — often across multiple layers such as infrastructure, applications, and identity.”

— CSA Security Guidance v4.0, Domain 9: Incident Response

CDR platforms typically include:

Threat detection across cloud workloads (e.g., compute, storage, IAM misuse)

Real-time alerts

Automated or manual response mechanisms

Integration with cloud-native logging services like AWS CloudTrail, Azure Monitor, or GCP Audit Logs

Incorrect options:

B is about application management, not threat detection.

C relates to cloud cost optimization tools.

D refers to cloud storage tuning, unrelated to threat detection.

Privilege escalationis a majorcloud security riskbecause attackers can:

Gain administrative access to cloud environments.

Modify security configurations, disable logs, and exfiltrate sensitive data.

Expand the attack blast radius, compromising multiple cloud resources.

To mitigateidentity escalation threats, security teams must:

Implement strong IAM policies with least privilege access.

Use Multi-Factor Authentication (MFA) and Just-in-Time (JIT) access.

Monitor IAM logs for unusual privilege escalations and lateral movements.

This is detailed in:

To reduce vulnerabilities in virtual machines (VMs) in a cloud environment, it is critical to use secure base images that are free from known vulnerabilities,ensure regular patching to fix any discovered security issues, and implement configuration management to ensure that VMs are properly configured according to security best practices. This combination of practices ensures that VMs are both secure from the start and remain secure over time as new vulnerabilities are discovered.

Disabling unnecessary VM services and using containers is a good security practice but does not directly address vulnerabilities in VMs specifically. Encryption and SBOM is important for securing data and understanding dependencies but does not specifically focus on reducing vulnerabilities in VMs. Network isolation and monitoring are key network security practices but do not directly address the security of the VMs themselves.

Cloud telemetry provides detailed insights and visibility into security events and system behaviors in cloud environments, which helps detect and respond to threats. Reference: [Security Guidance v5, Domain 6 - Security Monitoring]

The shared responsibility model is a key concept in cloud security. According to the CSA Security Guidance v4.0, Domain 1, Section 1.2.1, the responsibility for security is shared between the cloud provider and the customer, depending on the service model (IaaS, PaaS, SaaS).

Specifically:

"Infrastructure as a Service: Just like PaaS, the provider is responsible for foundational security, while the cloud user is responsible for everything they build on the infrastructure."

"At a high level, security responsibility maps to the degree of control any given actor has over the architecture stack."

This means the cloud provider handles the physical security (data center, servers, etc.), while the customer is responsible for securing the workloads they deploy on the infrastructure, such as their applications, data, configurations, and access controls.

Incorrect Options:

B is incorrect because providers do not manage your workload or data security.

C is false – both parties share responsibilities.

D is incorrect because customers do not manage the cloud’s physical infrastructure.

Kubernetes provides automated deployment, scaling, and management of containerized applications, which enhances operational efficiency and scalability. Reference: [CCSK v5 Curriculum, Domain 8 - Cloud Workload Security]

The correct answer isD. Virtual Machines (VMs). In the context of cloud computing,Virtual Machines (VMs)are software-based emulations of physical computers. They run an operating system (OS) and applications just like a physical machine would. VMs are often hosted on physical servers using hypervisors, which allow multiple VMs to run on a single physical machine, thereby sharing resources like CPU, memory, and storage.

Why Virtual Machines (VMs) are Suitable for Data Processing:

Full OS Environment:VMs provide a complete operating system environment, making them suitable for running complex data processing tasks that require specific OS configurations.

Isolation:Each VM operates independently, providing isolation between different workloads, which is essential when processing sensitive or diverse data sets.

Scalability:Cloud providers offer VM scaling options to meet the demands of data processing workloads.

Compatibility:VMs can run legacy applications that may not be compatible with newer cloud-native technologies.

Why Other Options Are Incorrect:

A. Platform as a Service (PaaS):PaaS provides a platform for developing and deploying applications without managing underlying infrastructure. It is not directly related to VM-based processing.

B. Serverless Functions (FaaS):Serverless computing abstracts the infrastructure and is used for running discrete functions rather than emulating entire machines.

C. Containers:Containers package applications and dependencies but share the host OS kernel. They are lightweight compared to VMs and do not fully emulate physical computers.

Real-World Example:

If a company moves a data processing application that was traditionally run on an on-premises physical server to the cloud, they might choose VMs on services like AWS EC2, Azure Virtual Machines, or Google Compute Engine to maintain the same OS environment and application compatibility.

In the CSA Security Guidance v4.0, Domain 12: Identity, Entitlement, and Access Management, authentication is explicitly defined as the process that verifies the identity of a user, process, or device before granting access.

"Authentication is the act of verifying the identity of a user, process, or device, often as a prerequisite to allowing access to resources in an information system."

— CSA Security Guidance v4.0, Domain 12

Here's what each term means:

Authentication = Verifies identity

Authorization = Determines access rights

Entitlement = Set of access rights assigned to a user

Assertion = Statement from an identity provider, often used in federation

So, authentication must happen before authorization. It's the first gate.
