InCrowdStrike Falcon Cloud Security, preventing a container process from altering its expected behavior is achieved throughcontainer drift preventionenforced by theFalcon Linux sensorat runtime.

Container drift occurs when a running container deviates from its original image state, such as when new binaries are written, files are modified, or unexpected processes execute. Drift is a strong indicator of compromise, misconfiguration, or malicious activity.

By enablingcontainer drift prevention on the Linux sensor, Falcon enforcesruntime immutability, ensuring that containers only execute binaries and processes that were present at image build time. Any unauthorized modifications or executions are either detected or actively blocked, depending on policy configuration.

Creating a custom IOA is not the most effective approach because IOAs are reactive and behavior-based rather than enforcing immutability. The Kubernetes Admission Controller operates at deployment time, not runtime, and cannot prevent post-deployment process changes. Image Assessment policies only affect image deployment decisions and do not control runtime behavior.

Therefore,Option Ais correct because container drift prevention is specifically designed toprotect runtime container integrity, ensuring containers behave exactly as expected throughout their lifecycle.

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.

To notify your team when anew executable is downloaded and executed inside a running container, you must use aruntime-focused triggerin Falcon Fusion. The correct selection isContainer detection > Container runtime detection.

Container runtime detections monitor live container behavior, including process execution, file writes, network activity, and binary downloads. When an executable is introduced and run at runtime, this represents potential malicious activity or policy violation that cannot be detected during image assessment.

Image Assessmenttriggers apply only to pre-runtime image scanning and cannot detect runtime execution.Container drift detectionfocuses on changes to container state relative to the original image but does not specifically target execution-based detections.

CrowdStrike Falcon Cloud Security documentation clearly distinguishes runtime detections as the correct signal source for SOAR automation involving live container behavior. Therefore, the correct trigger configuration isContainer detection > Container runtime detection.
