Compliance inheritance refers to the practice in cloud compliance where a customer leverages a set of pre-approved regulatory or standards-based controls that have been established and validated by a compliant cloud provider. Essentially, the cloud provider implements these controls, and the customer inherits the provider's compliance framework to meet their own regulatory requirements. This allows customers to benefit from the provider’s compliance efforts without having to implement everything themselves.

Automated compliance refers to automating compliance tasks and processes but does not describe the practice of inheriting compliance controls. Attestation inheritance is not a standard term used in cloud compliance; attestation typically refers to formally certifying or declaring compliance. Audit inheritance would relate to the inheritance of audit reports or records, but it doesn't describe the broader process of inheriting compliance controls.

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.

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.

IAM failures are a leading cause of cloud-native breaches, often due to misconfigurations or inadequate access control mechanisms. Reference: [Security Guidance v5, Domain 5 - IAM]

Multi-region resiliency in cloud environments is primarily used to improve fault tolerance by deploying applications and services across multiple geographical regions. This strategy ensures that if one region experiences an outage or failure, the application or service can failover to another region, maintaining availability and minimizing downtime. Multi-region deployments help organizations ensure business continuity, disaster recovery, and high availability.

Increasing the number of users in each region is not the main purpose of multi-region resiliency. While multi-region deployment can help with compliance, the primary goal is fault tolerance and availability, not compliance with data laws. While multi-region deployment may offer some efficiency benefits, the main purpose is not cost reduction; it's about ensuring reliability and availability.

TheCascade-and-filter approachis a method used in cloud security to handle incoming data logs efficiently. It prioritizes logs for threat detection byapplying multiple sequential filters, where each filter progressively narrows down the data. This approach helps in:

Layered threat detection:Early filters eliminate non-critical data, while subsequent filters perform more detailed analysis.

Efficient processing:Reduces the volume of data passed through advanced and resource-intensive filters.

Improved accuracy:Allows focusing on the most relevant security events.

For example, in a cloud environment, the first filter might check for known malicious IP addresses, the second might look for suspicious file types, and subsequent filters may perform behavioral analysis or anomaly detection.

Why Other Options Are Incorrect:

B. Parallel processing approach:This method processes logs simultaneously, not sequentially, and is less efficient for prioritizing threats.

C. Streamlined single-filter method:Uses a single filter for all data, which lacks depth and thoroughness in identifying complex threats.

D. Unfiltered bulk analysis:This approach is resource-intensive and inefficient, as it does not prioritize or filter logs.

Enforcing the principle of least privilege is the practice of granting users and systems the minimum level of access necessary to perform their tasks. By limiting root or core access and restricting the creation of deployments to onlythose who absolutely need it, the risk of unauthorized access, misuse, or damage is minimized. This helps ensure that critical systems and sensitive data are protected by reducing the number of people or services with high-level access.

Trust and verify on demand is not a standard security practice and could create security gaps. Disabling multi-factor authentication is a poor security practice, as multi-factor authentication (MFA) enhances security by adding an additional layer of verification. Deploying applications with full access) contradicts the principle of least privilege and could expose the system to unnecessary risks.

The Detection and Analysis phase involves identifying incidents and determining their impact. It is crucial to validate events to understand if they constitute a security incident. Reference: [Security Guidance v5, Domain 11 - Incident Response]

SLAs play a key role in cloud incident management as they define response expectations and support arrangements between CSPs and CSCs. Reference: [CCSK Study Guide, Domain 11 - Incident Response]

The primary objective of posture management in a cloud environment is to ensure that cloud configurations are continuously monitored to ensure compliance with security policies, best practices, and regulatory requirements.Posture management involves assessing and maintaining the security posture by identifying misconfigurations, vulnerabilities, or non-compliant resources, and ensuring that the cloud environment remains secure and aligned with organizational policies.

Automating incident response procedures is important but is not the primary focus of posture management, which focuses more on proactive configuration and security monitoring. Optimizing cloud cost efficiency is a key concern in cloud management, but it is not the main focus of posture management, which deals with security and compliance. Managing user access permissions is related to Identity and Access Management (IAM), which is a separate aspect of cloud security from posture management.

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.
