CCSK Exam Dumps - Cloud Security Alliance Cloud Security Knowledge Questions and Answers

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.

The division of security responsibilities changes according to the service model. In IaaS, CSCs handle more security responsibilities, while in SaaS, the CSP manages more of the security aspects. Reference: [Security Guidance v5, Domain 1 - Shared Responsibility Model][17†source].

An image factory is used in VM deployment to create standardized and secure virtual machine images. The primary role of the image factory is to automate the creation of these images, ensuring that all VMs deployed from the image are consistent in terms of configuration, security settings, and performance. By using an image factory, organizations can ensure that their VMs are secure (with the necessary security patches and settings), efficient (optimized for performance), and consistent (following the same configuration).

This process minimizes the risk of configuration drift and reduces manual intervention in VM deployment, leading to more efficient and secure operations.

A key benefit ofSoftware-Defined Networking (SDN)is that it allows networks to bedynamically configured and managed through software. SDN separates the control plane from the data plane, enabling centralized management and programmable network configurations, which improves flexibility and scalability in cloud environments.

From theCCSK v5.0 Study Guide, Domain 9 (Network Security), Section 9.3:

“Software-Defined Networking (SDN) enables dynamic configuration and management of networks through software, decoupling the control plane from the data plane. This allows organizations to programmatically adjust network policies and traffic flows, improving agility and scalability in cloud environments.”

Option C (SDN allows networks to be dynamically configured and managed through software) is the correct answer.

Option A (Hardware-based solution) is incorrect because SDN is software-based.

Option B (Eliminates physical devices) is incorrect because SDN still relies on physical infrastructure.

Option D (Focused on firewalls) is incorrect because SDN’s primary benefit is flexibility, not firewalls.

Correct Option: B. It ensures a systematic approach, minimizing damage and recovery time

Effective incident response planning is critical in cloud environments due to the shared responsibility model. When an incident affects the CSP, cloud customers must be prepared to coordinate response activities, ensure clarity of roles, and maintain continuity of operations.

From CSA Security Guidance v4.0 – Domain 9: Incident Response:

“Organizations must establish systematic and coordinated incident response plans for cloud incidents. This helps to reduce the impact, minimize damage, and shorten recovery time. Coordination with the CSP is vital to ensure responsibilities are understood and executed.”

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

The guidance emphasizes that preparation and communication channels with CSPs should be defined in advance, as delays in joint response can significantly increase the scope and impact of incidents.

Why the Other Options Are Incorrect:

A. It eliminates the need for monitoring systems➤ Incorrect. Monitoring remains essential for detecting incidents early. Planning and monitoring serve different functions.

C. It guarantees that no incidents will occur in the future➤ No system is immune to incidents. Planning reduces impact, but does not prevent incidents entirely.

D. It reduces the frequency of security audits required➤ Audits are required based on compliance and regulatory needs, not on incident response planning.
