CAS-004 Security Architecture Practice Question
An organization wants to enforce consistent security policies across multiple cloud providers (AWS, Azure, GCP). Which tool is designed to continuously monitor and remediate misconfigurations in cloud environments?
⚠ Common exam trap
CAS-005 often tests the confusion between CSPM (configuration posture) and CWPP (runtime workload protection) or CASB (data access control), so candidates must map the keyword 'misconfiguration' specifically to CSPM.

Correct answer & explanation
✓
Cloud Security Posture Management (CSPM)
CSPM (Cloud Security Posture Management) tools are purpose-built to continuously scan multi-cloud environments (AWS, Azure, GCP) against benchmarks like CIS, NIST, and PCI DSS, detecting misconfigurations such as public S3 buckets, overly permissive IAM roles, or unencrypted storage. They provide automated remediation workflows and drift detection across providers, which is exactly what the organization needs for consistent policy enforcement. CASB, SIEM, and CWPP address different layers (data access, log correlation, workload runtime) and do not natively deliver cross-cloud configuration posture management.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Cloud Access Security Broker (CASB)
Why it's wrong here
A CASB brokers access between users and cloud services, enforcing data-loss and access policies, but it does not scan infrastructure configurations for misconfigurations. It is tempting because CASBs do span multiple clouds, yet they govern SaaS usage rather than remediate resource settings.
- ✗
Security Information and Event Management (SIEM)
Why it's wrong here
A SIEM aggregates and correlates log events for detection and alerting, but it does not itself remediate misconfigured cloud resources. It is tempting because SIEMs ingest multi-cloud telemetry, which suits threat detection and compliance reporting rather than configuration enforcement.
- ✗
Cloud Workload Protection Platform (CWPP)
Why it's wrong here
A CWPP secures running workloads such as containers and virtual machines, not the cloud resource configurations that cause misconfigurations. It is tempting because CWPPs operate across providers, but their scope is runtime protection, whereas configuration posture management is the required capability.
- ✓
Cloud Security Posture Management (CSPM)
Why this is correct
CSPM continuously monitors multi-cloud infrastructure for misconfigurations and automatically remediates drift, satisfying the requirement to enforce consistent policy across AWS, Azure and GCP. Unlike native tools that operate within a single provider, CSPM normalises posture assessment across heterogeneous environments, directly addressing the cross-provider constraint in the stem.
