InCrowdStrike Falcon Cloud Security, theAccount Registrationsection is the authoritative location for monitoring thestatus of onboarded cloud accountsand identifyingdeployment or configuration issues.

FromCloud Security → Settings → Account Registration, security teams can view whether AWS, Azure, or GCP accounts are successfully connected, partially configured, or experiencing errors. This view highlights misconfigurations such as missing permissions, failed integrations, or incomplete setup steps that could prevent posture assessments or detections from functioning correctly.

Other settings areas serve different purposes: Automate focuses on remediation workflows, posture policies define compliance logic, and scan settings control assessment frequency. None provide direct visibility into onboarding health and deployment validation.

Therefore,Cloud security – Settings – Account registrationis the correct and verified answer.

To secure an AWS Elastic Kubernetes Service (EKS) cluster running on Amazon Linux 2–based EC2 instanceswith container-level visibility, CrowdStrike Falcon documentation identifies theFalcon Container Sensor for Linuxas the correct solution. This sensor is part of Falcon Cloud Security and is purpose-built to protect Kubernetes and containerized workloads.

The Falcon Container Sensor for Linux is deployed as a container (commonly as a DaemonSet) on each Kubernetes worker node. It integrates with the underlying Linux kernel to observe container runtime activity while maintaining Kubernetes awareness. This allows CrowdStrike to deliver deep visibility into container processes, file system activity, network connections, and inter-container behavior—capabilities that are not available with host-only sensors.

TheFalcon Sensor for Linuxprotects the EC2 host operating system but does not provide container-aware telemetry or Kubernetes context. TheFalcon Kubernetes Admission Controlleris a pre-runtime control used to enforce image and deployment policies at admission time, not to provide runtime detection.Image Assessment at Runtimeis a feature for evaluating container images and is not a deployable sensor.

Because the requirement explicitly includesruntime protection and container-level visibility within EKS, the Falcon Container Sensor for Linux is the only option that fully satisfies these needs according to CrowdStrike Falcon Cloud Security architecture and documentation.

Cloud Groups in CrowdStrike Falcon Cloud Security are designed to logically segment cloud resources so users can focus only on what is relevant to their role or responsibility. The primary way cloud groups reduce noise is bynarrowing a user’s scope of analysis through filtered cloud resources.

By grouping resources based on criteria such as account, region, service, or tags, Cloud Groups ensure that analysts and responders only see findings related to the resources they own or manage. This minimizes alert fatigue, reduces unnecessary exposure to unrelated findings, and improves investigation efficiency.

Cloud Groups do not assign permissions directly; permissions are managed through Falcon RBAC roles. They also do not primarily function as exclusion mechanisms—although exclusions may be applied, their core purpose is scoping and contextualization.

CrowdStrike best practices emphasize Cloud Groups as a way to align security visibility with organizational structure, enabling teams to operate more efficiently and responsibly. Therefore, the correct answer isNarrow a user’s scope of analysis by filtering cloud resources.

When registering an individual AWS account in CrowdStrike Falcon Cloud Security using the Falcon UI, therecommended and supported method is AWS CloudFormation. CrowdStrike provides a prebuilt CloudFormation template that automates the creation of required AWS resources, including IAM roles, permissions, and trust relationships needed for secure, read-only API access.

Using CloudFormation ensures the deployment isconsistent, auditable, and aligned with AWS best practices. It minimizes human error by automatically configuring the correct permissions required for Falcon to collect configuration, identity, and resource metadata from AWS. This method also simplifies lifecycle management—resources can be updated or removed cleanly by managing the CloudFormation stack.

Other options are not recommended for this use case.AWS Configis a native AWS compliance service but does not handle Falcon onboarding.Terraform scriptsmay be used in advanced or large-scale automation scenarios, but they are not the default or recommended approach for single-account registration in the Falcon UI.Bash scriptslack governance, validation, and repeatability.

Therefore, when registering a single AWS account through the Falcon console,AWS CloudFormationis the correct and CrowdStrike-recommended method.
