A common cloud-conscious attacker technique used to remain hidden in a compromised environment is disabling CloudTrail logging . AWS CloudTrail records API activity across an account, providing critical visibility into actions taken by users, roles, and services. By disabling or tampering with CloudTrail, attackers significantly reduce the likelihood of detection.

CrowdStrike Falcon Cloud Security classifies this behavior as a high-risk indicator because it directly impacts monitoring, forensics, and incident response. Without CloudTrail logs, security teams lose audit trails that are essential for identifying malicious actions such as privilege escalation, data exfiltration, or persistence mechanisms.

Other options represent misconfigurations or changes that may increase exposure but do not directly suppress visibility. For example, modifying storage networking or security groups increases attack surface, while adding certificates may support persistence—but none are as directly linked to stealth as disabling logging.

Therefore, CloudTrail logging disabled is the correct answer and a well-documented cloud attack tactic used to evade detection.

CrowdStrike Falcon Cloud Security strongly recommends shifting security left in the development lifecycle by integrating image assessment directly into the CI/CD pipeline . This approach ensures vulnerabilities are detected during the build process , before images are deployed into production environments.

By pushing container images to Falcon for assessment as part of CI/CD workflows, Falcon expands image layers, inventories binaries and OS packages, and evaluates vulnerabilities early. This enables development and security teams to remediate issues before deployment, reducing risk exposure and preventing vulnerable images from ever reaching runtime.

Runtime-only analysis and host-based tools are insufficient for proactive security, as they detect issues after exposure has already occurred. Manual inspection does not scale and introduces human error, making it unsuitable for modern DevOps pipelines.

Therefore, integrating automated image assessment into CI/CD pipelines is the CrowdStrike best practice for secure container deployments.

To secure an AWS Elastic Kubernetes Service (EKS) cluster running on Amazon Linux 2–based EC2 instances with container-level visibility , CrowdStrike Falcon documentation identifies the Falcon Container Sensor for Linux as 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.

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

Because the requirement explicitly includes runtime 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.

CrowdStrike Falcon Cloud Security performs agentless cloud security posture management (CSPM) by integrating directly with cloud service providers such as AWS, Microsoft Azure, and Google Cloud Platform using native APIs. This approach allows Falcon to continuously assess cloud configurations, permissions, networking, storage, and identity controls without deploying sensors or agents.

By default, CrowdStrike configures cloud account scans to run every 4 hours . This scan frequency is designed to strike a balance between near-real-time visibility and efficient API usage across cloud providers. Cloud environments are highly dynamic, with frequent changes to configurations, IAM policies, and services. A four-hour scan interval ensures that new misconfigurations or risky changes—such as overly permissive roles, exposed storage, or insecure network rules—are identified quickly enough to reduce exposure time.

Scanning more frequently could introduce unnecessary API throttling or operational overhead, while less frequent scans could delay detection of critical security gaps. The four-hour interval is therefore CrowdStrike’s recommended default for maintaining continuous visibility while preserving cloud provider performance and stability.

This default interval can be adjusted in certain scenarios, but unless explicitly changed, every 4 hours is the standard scan cadence applied to AWS, Azure, and GCP environments.

In CrowdStrike Falcon Cloud Security, exclusions for cloud scans are designed to be precise and scalable so that organizations can safely reduce noise without weakening overall security coverage. According to CrowdStrike best practices, tags are the recommended and supported criterion for creating cloud scan exclusions.

Tags are metadata labels applied to cloud resources (such as AWS accounts, instances, or services) and are commonly used for ownership, environment classification (for example, dev, test, or prod), or application grouping. By using tags as exclusion criteria, security teams can dynamically control which resources are excluded from scans without relying on static identifiers. This is especially important in cloud environments where resources are frequently created, modified, or terminated.

Exclusions based on accounts , regions , or services are broader in scope and can unintentionally exclude large portions of the environment, increasing the risk of blind spots. Tag-based exclusions allow CrowdStrike Falcon to maintain least-privilege security principles by excluding only explicitly labeled resources.

Because Falcon continuously evaluates cloud resources, tag-based exclusions automatically apply to newly created assets that inherit the same tag, ensuring consistent policy enforcement. For these reasons, CrowdStrike documentation and operational guidance identify Tag as the correct and most effective criterion for creating cloud scan exclusions.

According to CrowdStrike Falcon documentation regarding Falcon Cloud Security (FCS) and Container Security , the method used to deploy sensors significantly impacts how updates are managed. When Linux hosts are part of a Kubernetes cluster and the Falcon sensor is deployed as a DaemonSet , the standard "Sensor Update Policy" configured in the Falcon Console does not automatically trigger a version change in the same way it does for a standard Windows or Linux workstation.

In a DaemonSet deployment , the sensor version is typically tied to the specific container image tag or the version defined in the Helm chart or YAML manifest used during deployment. If the manifest specifies a static version or if the orchestration layer (Kubernetes) is not instructed to pull a newer image and rollout a restart of the DaemonSet pods, the hosts will remain on their current version regardless of the "n-2" policy set in the console.

Furthermore, CrowdStrike documentation notes that for Linux Sensor Update Policies , the "n-2" setting dictates which version is assigned to the host, but the mechanism of delivery must be supported. In containerized environments, the "Auto-update" feature is often bypassed by the immutable nature of the deployment. To resolve this, the administrator must update the DaemonSet configuration to point to the newer sensor image, allowing Kubernetes to perform a rolling update across the nodes.

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 by narrowing 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 is Narrow 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, the recommended 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 is consistent, 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 Config is a native AWS compliance service but does not handle Falcon onboarding. Terraform scripts may 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 scripts lack governance, validation, and repeatability.

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

The secure and recommended way to test whether firewall restrictions are causing CSPM operation failures is to verify that the required CrowdStrike IP addresses are allowlisted. Falcon Cloud Security relies on outbound API communication between CrowdStrike and the cloud provider. If firewall rules block this traffic, asset inventory collection and IOM detection can fail even though registration appears successful.

CrowdStrike publishes a list of IP addresses and endpoints that must be permitted for proper operation. Validating firewall allowlists against this documentation is a low-risk, best-practice troubleshooting step that preserves security controls while testing connectivity assumptions.

Temporarily opening firewalls to all inbound traffic is insecure and strongly discouraged. Dismissing firewall-related causes without validation can delay resolution. Therefore, the correct and secure approach is to check that the CrowdStrike IP addresses are allowlisted.

In CrowdStrike Falcon Cloud Security, Cloud Groups are used to logically group container images so that policies, assessments, and controls can be applied consistently across workloads. When editing or defining a Cloud Group for container images, Falcon allows administrators to select specific image properties to precisely target the desired scope.

The three supported image properties are Registry, Repository, and Tag .

Registry identifies where the container image is hosted, such as Amazon ECR, Azure Container Registry, or Docker Hub.

Repository defines the image namespace or project within the registry.

Tag specifies the image version or variant (for example, latest, v1.2.3, or prod).

Using these three properties together enables highly granular targeting. For example, security teams can apply stricter policies only to production-tagged images from a specific registry and repository, while allowing more flexibility for development images.

Options that include Name are incorrect because CrowdStrike does not use a standalone “image name” field when defining Cloud Group image criteria. Instead, image identity is derived from the combination of registry, repository, and tag.

Therefore, the correct and fully supported selection is Registry, Repository, and Tag , which aligns with CrowdStrike Falcon Cloud Security configuration and documentation.
