The correct answer isD. Cloud systems automatically monitor resource usage and provide billing based on actual consumption.

Measured Service is one of theessential characteristics of cloud computingas defined by theNIST (National Institute of Standards and Technology). It implies that cloud systems automatically control and optimize resource usage by leveraging ametering capability. This capability tracks and reports resource consumption (such as CPU, storage, or bandwidth), which is used for billing, monitoring, and planning.

Key Characteristics:

Automatic Monitoring:Cloud platforms continuously track resource usage without manual intervention.

Billing Based on Usage:Customers are billed based on the actual consumption of resources (pay-as-you-go model).

Transparency:Users can view detailed usage reports to understand their resource utilization and associated costs.

Resource Optimization:Providers use these metrics to optimize resource allocation and improve efficiency.

Why Other Options Are Incorrect:

A. Fixed immutable set of measured services:This contradicts the concept of elasticity and resource pooling in cloud computing.

B. Elastic resources:While elasticity is a cloud characteristic, it does not directly define measured service.

C. Manual reporting:Measured service is aboutautomated, real-time monitoring and billing, not manual data gathering.

Real-World Example:

In AWS, services likeAmazon CloudWatchautomatically collect and provide usage metrics, and the AWS Billing Console shows the cost associated with each resource.

The correct answer isD. Cloud Security Posture Management (CSPM).

Cloud Security Posture Management (CSPM) is a comprehensive tool designed to identify and remediate misconfigurations and compliance violations incloud management planes. It helps organizations maintain secure and compliant cloud environments by continuously monitoring configurations against industry standards and best practices.

Key Functions of CSPM:

Configuration Management:Identifies misconfigurations and alerts administrators to fix them.

Compliance Monitoring:Continuously assesses cloud environments against compliance frameworks such as CIS, NIST, GDPR, and others.

Automated Remediation:Automatically fixes known configuration errors based on predefined policies.

Visibility:Provides a comprehensive view of security and compliance risks across multi-cloud environments.

Risk Assessment:Analyzes risks related to identity, data exposure, and network configurations.

Why CSPM is Most Effective:

Cloud environments are dynamic, and maintaining secure configurations is challenging. CSPM solutions likeAWS Config,Azure Security Center, andGoogle Cloud Security Command Centerautomate the process of checking forsecurity policy violationsandconfiguration drift.

Why Other Options Are Incorrect:

A. Data Security Posture Management (DSPM):Focuses on data security, data loss prevention, and data governance, rather than configuration and compliance management.

B. SaaS Security Posture Management (SSPM):Specifically targets SaaS applications, managing security settings and compliance of cloud-based software rather than infrastructure.

C. Cloud Detection and Response (CDR):Focuses on threat detection and incident response rather than configuration management and compliance.

Real-World Example:

A CSPM tool likePalo Alto Prisma CloudorAWS Configcan automatically detect ifIAM policiesare overly permissive or ifS3 bucketsare publicly accessible, helping to maintain compliance and reduce attack surfaces.

Network segmentation isolates sections of the network, limiting the spread of a breach and containing it to a specific segment. Reference: [Security Guidance v5, Domain 7 - Infrastructure & Networking]

Cloud security control objectives are designed to provide outcome-focused guidelines that help organizations achieve specific security goals in the cloud. These objectives are typically high-level and focused on the desired security outcomes, rather than dictating the exact technical implementation methods. This allows the security measures to be adaptable and applicable across different cloud environments and service models, while also being measurable to ensure effectiveness.
