Cloud Security Alliance CCSK Exam With Confidence Using Practice Dumps

The most significant challenge in assessing cloud providers is the limited visibility into the provider's internal security controls, operations, and technology. Cloud customers often lack direct access to the infrastructure, policies, and mechanisms behind the cloud service due to the shared responsibility model and provider confidentiality.

According to CSA Security Guidance v4.0 – Domain 4: Compliance and Audit Management:

“The cloud customer’s inability to see and assess the cloud provider’s security controls and practices—known as limited visibility—is one of the most critical barriers to cloud assurance.”

(CSA Security Guidance v4.0, Domain 4: Compliance and Audit Management)

This is further echoed in CCM (Cloud Controls Matrix):

AAC-03 (Audit Assurance and Compliance) – “Cloud providers should make sufficient audit mechanisms available to allow the customer to assess control implementation. Lack of visibility significantly impacts trust and compliance validation.”

The other options may contribute to audit difficulties, but D represents the core, systemic challenge faced in cloud provider assessments.

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.

The Principle of Least Privilege (PoLP) is a foundational concept in IAM, highlighted in the CSA Security Guidance v4.0 – Domain 12: Identity, Entitlement, and Access Management. It ensures users, systems, and processes are granted only the permissions necessary to perform their tasks — and nothing more.

“Least privilege refers to granting the minimum level of access — or permissions — needed for users or services to perform their required functions, thereby reducing the attack surface and limiting potential damage from misuse or compromise.”

— CSA Security Guidance v4.0, Domain 12

This principle:

Reduces the likelihood of accidental or malicious misuse

Limits damage in the case of credential theft

Supports compliance with least privilege mandates in frameworks like ISO/IEC 27001 and NIST

Incorrect options:

B is related to federation, not least privilege

C involves monitoring and analytics, not permission assignment

D is about defense in depth, which is broader than PoLP
