You are a security analyst reviewing logs in the CrowdStrike Falcon platform. You notice unusual activity involving the repeated execution of a legitimate application, powershell.exe, with a base64-encoded string passed as a parameter.
Which of the following is the most likely explanation for this behavior, and what should be your next step?
- A . An administrator running legitimate scripts to automate system tasks.
- B . A malicious actor executing a PowerShell script for credential dumping.
- C . Routine software update activities performed by the IT department.
- D . A system error causing the repeated execution of PowerShell.
B
Explanation:
Option A: While administrators might use PowerShell for automation, it’s uncommon to encode commands in base64 unless there’s a specific need to obfuscate. This could indicate suspicious activity. Additional context, like logs or administrator intent, is required to confirm this as legitimate.
Option B: This behavior is highly indicative of malicious activity. PowerShell, especially when invoked with encoded commands, is a common vector used by attackers for credential dumping or executing malicious scripts. Reviewing the command and decoding the base64 string is essential to determine the exact purpose of the script. You should isolate the system and conduct further analysis to confirm and mitigate the threat.
Option C: Software updates rarely require PowerShell scripts with encoded commands. Confirming this scenario would require verifying the activity against scheduled update logs or communication from the IT team.
Option D: System errors can lead to unexpected behavior, but they are unlikely to involve encoded commands passed to powershell.exe. Such activity should be treated as suspicious until proven otherwise.
After identifying an account with unnecessary access privileges using the CrowdStrike CIEM/Identity Analyzer, what is the best action to mitigate risks?
- A . Downgrade permissions to "read-only" for all resources.
- B . Transfer the account’s permissions to a shared admin account for operational efficiency.
- C . Delete all permissions for the account immediately.
- D . Implement the principle of least privilege by aligning permissions with the account’s actual usage.
D
Explanation:
Option A: While "read-only" permissions reduce risk, this blanket approach might hinder required operations if the account needs more specific access. Permissions should match the actual usage needs.
Option B: Using shared accounts violates best practices for identity and access management (IAM).
Shared accounts obscure accountability and increase the risk of privilege misuse.
Option C: Deleting permissions without assessing operational needs can disrupt workflows and lead to unintended downtime. A more measured approach is required.
Option D: The best approach to mitigate risks is to reduce the account’s permissions to only what is necessary for its current activities. This minimizes the potential for misuse or exploitation while maintaining operational functionality.
What is the best approach to handle the output of the Falcon CWPP Image Scanning Script to ensure vulnerabilities are addressed effectively?
- A . Parse the output to filter critical vulnerabilities and send alerts to the security team.
- B . Disable output logging for sensitive image scans to ensure security.
- C . Ignore the script output in the pipeline and review results manually later.
- D . Automatically fail the pipeline if any vulnerabilities are found, regardless of severity.
A
Explanation:
Option A: Filtering critical vulnerabilities ensures that the most significant issues are addressed promptly while allowing the pipeline to continue for lower-priority issues. This approach balances security and productivity effectively.
Option B: Disabling logging hinders visibility into vulnerabilities. Security concerns about logs can be mitigated through secure storage and access control rather than disabling logging altogether.
Option C: Ignoring the script output negates the value of integrating the Image Scanning Script into the pipeline. Automated handling ensures vulnerabilities are addressed consistently and promptly.
Option D: Automatically failing the pipeline for all vulnerabilities, including low and informational ones, can disrupt development unnecessarily. The severity of vulnerabilities should be considered before deciding on pipeline actions.
Which step is essential when registering a cloud account in Falcon Cloud Security?
- A . Deploying the Falcon agent on all instances in the account before registration.
- B . Configuring automatic backup settings for all cloud resources.
- C . Configuring network firewalls to route all traffic through CrowdStrike’s servers.
- D . Enabling API access and permissions to allow CrowdStrike to monitor the account.
D
Explanation:
Option A: Agent deployment is not required before registration. Registration involves API integration, and agent-based workload protection is a separate step that comes later in the configuration process.
Option B: Automatic backup settings are unrelated to the registration process. Backup configurations are part of general cloud management and are not tied to CrowdStrike’s account registration requirements.
Option C: Routing traffic through CrowdStrike’s servers is not part of the account registration process.
CrowdStrike uses API-level integration for monitoring and protection, not network traffic routing.
Option D: Enabling API access and assigning the appropriate permissions is a critical step when registering a cloud account. These permissions allow Falcon Cloud Security to interact with and monitor cloud resources effectively.
Which of the following is the most critical step when configuring an automated remediation workflow in Falcon Fusion for AWS findings?
- A . Configure the workflow to delete all flagged resources immediately upon detection.
- B . Ensure IAM roles in AWS grant unrestricted access for remediation actions.
- C . Set up appropriate triggers and actions for specific AWS findings.
- D . Integrate AWS Security Hub with Falcon Fusion to detect findings.
C
Explanation:
Option A: Automatically deleting resources without evaluating their impact is risky. Automated remediation should take precise, context-aware actions rather than broad, potentially destructive ones.
Option B: Granting unrestricted IAM permissions violates the principle of least privilege and can expose the AWS environment to unnecessary risks. IAM permissions should be narrowly scoped for specific actions.
Option C: Automated remediation workflows require clear triggers (e.g., specific findings in AWS Security Hub) and actions (e.g., isolating instances or removing permissions) to function effectively. Configuring workflows with precise conditions ensures that remediation actions address relevant threats without unintended consequences.
Option D: While integration is necessary to collect AWS findings, it is not sufficient on its own to configure an automated remediation workflow. Integration is a preliminary setup step, not the critical configuration step.
An enterprise using Kubernetes wants to enforce a security policy that ensures all deployed containers originate only from their private container registry (registry.example.com).
What is the best way to achieve this using an admission controller?
- A . Use a Kubernetes NetworkPolicy to restrict egress traffic to public container registries
- B . Use a PodSecurityPolicy (PSP) to define allowed image sources
- C . Use RBAC to restrict users from pulling images from unauthorized registries
- D . Use a ValidatingWebhookConfiguration to reject pods that use images from untrusted registries
D
Explanation:
Option A: NetworkPolicies do not control which images can be pulled, only how network traffic flows between pods. Attackers could still use unauthorized images that were already pulled and cached.
Option B: PodSecurityPolicies (PSPs) are deprecated and cannot enforce image sources. Even when PSPs were in use, they did not provide controls for restricting container images based on registries.
Option C: RBAC rules control permissions related to Kubernetes objects but do not directly prevent the use of unauthorized container images.
Option D: A ValidatingWebhookConfiguration can be set up to inspect pod specifications and deny any that use images not sourced from registry.example.com. This provides a centralized and enforceable policy.
Which three image attributes can a cloud group be applied to?
- A . Image registry, Image repository, and Image tag
- B . Image cloud, Image registry, and Image repository
- C . Image type, Image tag, and Image registry
- D . Image version, Image repository, and Image tag
A
Explanation:
In CrowdStrike Falcon Cloud Security, Cloud Groups can be applied to container images using three specific image attributes: Image registry, Image repository, and Image tag. These attributes uniquely identify container images and allow precise scoping of policies and visibility.
Image registry identifies where the image is hosted (for example, Amazon ECR or Docker Hub).
Image repository defines the namespace or project within that registry.
Image tag specifies the version or variant of the image.
Together, these attributes provide a consistent and cloud-native method to group images across environments. Other attributes such as image version or type are not used as Cloud Group selectors in Falcon. Therefore, the correct answer is Image registry, Image repository, and Image tag.
An organization wants to integrate their private image registry with CrowdStrike for image assessment.
What must they configure in CrowdStrike Falcon to register the connection?
- A . Install the CrowdStrike sensor on the container registry server.
- B . Use default connection settings, as CrowdStrike auto-discovers private registries.
- C . Open the container registry to public access for CrowdStrike to retrieve images.
- D . Specify the registry URL, credentials, and authentication method in the Falcon console.
D
Explanation:
Option A: Installing a CrowdStrike sensor on the registry server is not necessary for integrating image scanning. The connection is established through the Falcon console configuration.
Option B: CrowdStrike does not auto-discover registries. You must manually configure the connection by providing the necessary details in the Falcon console.
Option C: Opening the registry to public access is a major security risk. CrowdStrike requires proper authentication and secure communication rather than public access to perform image assessments.
Option D: The integration requires you to register the registry in the CrowdStrike Falcon console by specifying the registry’s URL, credentials, and authentication method. This ensures secure communication between the registry and CrowdStrike, enabling image scanning.
A multi-cloud security engineer is responsible for managing cloud security across AWS, Azure, and Google Cloud. The engineer wants to ensure that only specific team members can onboard new cloud accounts into CrowdStrike Falcon Cloud Security.
Which Falcon role must be assigned to grant users permission to onboard cloud accounts?
- A . Falcon Administrator
- B . Falcon Threat Hunter
- C . Falcon Cloud Security Onboarding
- D . Falcon Viewer
C
Explanation:
Option A: While Falcon Administrators have full access to CrowdStrike Falcon, assigning this role just for cloud onboarding is not a best practice. Overuse of administrative privileges increases security risks.
Option B: The Falcon Threat Hunter role allows security professionals to conduct threat hunting and forensic analysis but does not include permissions for cloud account registration.
Option C: The Falcon Cloud Security Onboarding role is specifically designed for registering and managing cloud accounts within Falcon Cloud Security. This role ensures that users can onboard AWS, Azure, and GCP accounts while maintaining security and compliance without having unnecessary administrative privileges.
Option D: The Falcon Viewer role is read-only, meaning users with this role cannot onboard new cloud accounts or make configuration changes. It is designed for security monitoring, not for account registration.
Which step is most critical in analyzing findings and detections in CrowdStrike Falcon for effective remediation?
- A . Disable all detection policies temporarily to prevent further findings.
- B . Reclassify the detection as a false positive to avoid generating alerts.
- C . Review the detection details to understand the root cause and attack chain.
- D . Immediately quarantine the impacted host without reviewing detection details.
C
Explanation:
Option A: Disabling detection policies creates blind spots in security monitoring, making the environment more vulnerable. Policies should be fine-tuned, not deactivated.
Option B: Reclassifying a detection as a false positive without proper investigation can allow threats to persist in the environment. Accurate classification is essential for maintaining security posture.
Option C: Reviewing detection details provides critical insights into the attack chain, including how the threat was introduced and propagated. This step allows for a comprehensive understanding of the incident, enabling targeted and effective remediation. Skipping this step could lead to incomplete resolution or recurrence of the issue.
Option D: While quarantining a host can prevent further damage, doing so without understanding the detection context may result in unnecessary disruption or an incomplete response to the incident.
