CCSK Exam Dumps - Certificate of Cloud Security Knowledge v5 (CCSKv5.0)

Documenting lessons learned is essential in the post-incident phase, as it helps improve future incident response processes. Reference: [Security Guidance v5, Domain 11 - Incident Response]

The correct answer isB. Implementation of robust IAM and network security practices.

Ahybrid cloud environmentinvolves integrating private and public cloud infrastructures. This setup requires enhanced security practices to manage the complexity and diverse security requirements of both environments.

Key Aspects:

Identity and Access Management (IAM):Ensures secure authentication and authorization across both private and public clouds.

Network Security:Includes securing data in transit, implementing network segmentation, and protecting communication between cloud environments.

Unified Security Policies:Establishing consistent policies and access controls across both environments.

Visibility and Monitoring:Continuous monitoring of network traffic and access logs to detect potential threats.

Why Other Options Are Incorrect:

A. Encryption for data at rest:Important but not the most comprehensive security measure for hybrid environments.

C. Software updates and patch management:While essential, these practices alone do not address the complex challenges of a hybrid setup.

D. Multi-factor authentication only:MFA enhances authentication security but does not cover the broader security requirements of a hybrid cloud.

Real-World Context:

Organizations using services likeAWS Direct ConnectorAzure ExpressRouteto integrate on-premises environments with the public cloud must implement robust IAM and network security practices to maintain secure and compliant data flows.

The CSA Security Guidance v4.0, Domain 9: Incident Response highlights that traditional forensic techniques don't always apply in cloud-native environments like containers and serverless platforms. Instead, forensic investigators must capture ephemeral data such as logs, snapshots, and execution traces early and often.

“Forensic techniques must adapt to cloud-native environments such as containers and serverless. Important forensic data — including container logs, snapshots, and function execution logs — may be short-lived or non-persistent, so timely collection is critical.”

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

Key points:

Containers and serverless functions are often short-lived.

You need to capture logs and memory state before they're destroyed.

Serverless platforms (like AWS Lambda, Azure Functions) often provide execution logs via services like CloudWatch or Application Insights.

Incorrect options:

A: EDR is typically focused on traditional endpoints, not containers/serverless.

B: Useful in general, but not specific or always applicable to serverless/container forensics.

C: Antivirus doesn’t apply well to ephemeral or function-based environments.
