CCSK Cloud Security Alliance Certificate of Cloud Security Knowledge v5 (CCSKv5.0) Free Practice Exam Questions (2025 Updated)

Correct Option: A. Failure to update access controls after employee role changes

This falls under one of the most common risk factors related to cloud misconfiguration and poor change management. Misconfiguration errors often stem from insufficient change control, especially in dynamic environments like the cloud. According to CSA’s Security Guidance v4.0, poor governance of identity and access management (IAM) changes — such as not updating access privileges when user roles change — introduces serious security risks.

"Cloud computing is dynamic by nature. This places more importance on automation and proper governance, especially for identity and access control. Failure to remove or update access permissions after personnel changes leads to orphaned or over-permissioned accounts, which are prime targets for attackers."

— Domain 2: Governance and Enterprise Risk Management, CSA Security Guidance v4.0

Also highlighted in ENISA’s Cloud Risk Assessment:

"Loss of governance includes failing to maintain proper control over access privileges and role assignments. Poor change management and inadequate configuration reviews can leave systems open to unauthorized access."

— ENISA Cloud Computing Risk Assessment, Section R.2: Loss of Governance

Why the Other Options Are Incorrect:

B. Lack of sensitive data encryption: While encryption is critical, it is not directly tied to change control or misconfiguration, but rather falls under Data Security and Encryption domain.

C. Lack of 3rd party service provider specialized in patch management procedures: This refers more to vendor management and Security-as-a-Service, not internal change control or misconfigurations.

D. Excessive SBOM focus: Software Bill of Materials (SBOM) is important for supply chain transparency, but excessive focus on it isn’t a typical misconfiguration or change control risk.

Identity management at the organizational level is a key aspect of cybersecurity because it ensures that only authorized users can access specific resources, systems, or data. By controlling and managing user identities, roles, and permissions, identity management helps enforce security policies, preventing unauthorized access and potential breaches. This is a fundamental practice in maintaining confidentiality, integrity, and availability within an organization.

Immutable containers are not altered post-deployment, ensuring the integrity of the deployed environment and reducing the risk of unauthorized modifications. Reference: [CCSK v5 Curriculum, Domain 8 - Cloud Workload Security][16†source].

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 primary function of Privileged Identity Management (PIM) and Privileged Access Management (PAM) is to manage the risk of elevated permissions. These systems are designed to control and monitor access to sensitive resources and actions by users with elevated or privileged access rights, such as administrators. By managing these privileged accounts and ensuring they are granted only when necessary, for the least amount of time, and with appropriate oversight, organizations reduce the risk of misuse or abuse of these powerful permissions.

This helps protect critical systems and sensitive data from being compromised by unauthorized access, which is especially important for maintaining the security of IT environments.

Multi-region resiliency enhances infrastructure resilience bydistributing resources across multiple geographic locations, reducing the impact of regional outages. Reference: [Security Guidance v5, Domain 7 - Infrastructure & Networking]

InInfrastructure as a Service (IaaS), the customer has themost control and security responsibilitybecause:

The provider only secures physical infrastructure (data centers, networking, hardware).

Customers must configure and manage firewalls, network security, operating system patches, and IAM.

Data security, encryption, and application security are entirely the customer's responsibility.

In contrast:

PaaS (Platform as a Service)places some security responsibility on the provider (e.g., runtime environments, managed databases).

SaaS (Software as a Service)places most security responsibility on the provider, with customers mainly managingidentity and access controls.

This is extensively discussed in:

CCSK v5 - Security Guidance v4.0, Domain 1 (Cloud Computing Concepts and Architectures)

Cloud Controls Matrix (CCM) - Infrastructure and Application Security Controls​.

In a cloud context, entitlement refers to the specific resources or services a user is granted permission to access based on their roles or permissions. This includes access to applications, data, or cloud services, and is typically managed through Identity and Access Management (IAM) systems, which define what users can do and what they can access within the cloud environment.

An authoritative source in the context of identity management refers to a trusted system that contains accurate identity information. This system is considered the source of truth for identities, and other systems or services within the organization rely on it for the most up-to-date and verified identity details, such as usernames, attributes, roles, and permissions.

A list of permissions assigned to different users represents access control data but is not considered the authoritative source of identity. A network resource that handles authorization requests refers to authorization mechanisms but is not the authoritative source for identity. A database containing all entitlements could be part of an identity management system but is not necessarily the authoritative source for identity itself; it focuses more on access rights and entitlements.

A VPN (Virtual Private Network) is commonly used to provide secure, encrypted connections between on-premises data centers and cloud deployments, ensuring that data transmitted across the internet is protected from unauthorized access. VPNs help safeguard sensitive information byencrypting the communication channel, offering confidentiality and integrity for the data in transit.

VPNs are not necessarily more cost-effective than other options like dedicated private connections or direct connect services, especially when considering performance and reliability. While VPNs provide secure connections, they do not eliminate the need for third-party authentication services, which are still important for controlling access. VPNs typically offer lower bandwidth and higher latency compared to direct connection solutions, which are designed for higher-performance use cases.

In a cloud computing incident, the initial focus of analysis should be on the management plane activity logs due to the ephemeral nature of resources and centralized control mechanisms in cloud environments. The management plane controls and monitors the overall cloud infrastructure, and its activity logs provide crucial information about changes to configurations, access controls, resource provisioning, and administrative actions that can help identify the root cause of an incident.

Network perimeter monitoring and endpoint protection status are also important, but in cloud environments where resources can be rapidly provisioned and decommissioned, the management plane logs provide the most immediate insight into administrative actions and the overall state of the cloud environment.

Physical hardware access is generally the responsibility of the cloud provider and less relevant in the initial stages of a cloud incident analysis, especially when focusing on virtualized and managed resources.

The most effective way to identify security vulnerabilities in an application is to conduct automated and manual security testing throughout the development lifecycle. This approach ensures that security is continuously evaluated at every stage of development, rather than waiting until the end. Automated tools can help identify common vulnerabilities quickly, while manual testing allows for more in-depth analysis, including testing for complex, contextual security issues. This proactive and ongoing approach reduces the risk of vulnerabilities being overlooked and helps ensure that security is integrated into the application from the start.

Performing code reviews just prior to release is valuable, but it’s not comprehensive enough. Security testing should be done early and continuously, not just before release. Relying solely on secure coding practices is important but not sufficient. Even with secure coding practices, testing is essential to identify vulnerabilities. Waiting for a single penetration test after development is not effective because waiting until the end can allow many vulnerabilities to go unnoticed during development, leaving the application exposed.

“An Acceptable Use Policy (AUP) defines appropriate and prohibited uses of organizational IT resources, including cloud services.”

Context-aware IAM enables access decisions that account for real-time conditions, enhancing security by adapting to changes in user and resource status. Reference: [CCSK Study Guide, Domain 5 - IAM]

Cloud adoption transforms how incident response (IR) is conducted. Unlike traditional IT environments, cloud environments involve shared responsibility, provider collaboration, and remote orchestration. This shift requires security teams to adjust response strategies, tools, and governance to effectively detect, analyze, and remediate incidents.

Cloud-specific tools (e.g., CSP logs, API calls, auto-scaling environments) must be incorporated into IR plans. Coordination with cloud service providers is often necessary to access logs, enforce controls, or conduct forensics.

This transformation is outlined in Domain 9: Incident Response, which stresses that effective IR in the cloud must be pre-planned and adapted to each provider and cloud model.

Integrating testing early helps identify security vulnerabilities and configuration issues before they reach production, reducing remediation costs and time. Reference: [Security Guidance v5, Domain 10 - Application Security]
