Option A: Deploying the Falcon sensor ensures the VM is brought under management and monitoring. Restricting network access limits exposure while updating the software addresses known vulnerabilities. This approach effectively mitigates risk without unnecessarily disrupting operations.
Option B: While assigning the VM to a restricted group might help limit its access, it does not address the root cause of its vulnerabilities or the associated risks. Further actions, such as deploying the Falcon sensor and updating the software, are required.
Option C: Ignoring the VM leaves it vulnerable to exploitation, increasing the risk of a breach.
Proactive steps are necessary to mitigate potential threats before they escalate.
Option D: Immediate termination could disrupt legitimate operations if the VM serves a business purpose. A more measured approach involves securing and updating the asset.

Option A: Pre-deployment scanning with enforcement ensures that only secure images are deployed, blocking those with critical vulnerabilities. This helps mitigate security risks before they reach production.
Option B: While notifying administrators about vulnerabilities is useful, allowing all images regardless of severity increases risk by deploying insecure workloads.
Option C: Relying on manual assessments makes security processes inefficient and inconsistent, leading to gaps in protection.
Option D: Post-deployment scanning is useful for continuous monitoring, but it does not prevent vulnerable images from being deployed in the first place.

Option A: Falcon RTR is a powerful tool for incident response, but immediate file deletion without forensic validation can lead to loss of evidence and potential operational impact. Security teams should analyze files before taking action.
Option B: While isolating affected workloads may be necessary, immediately shutting them down could erase critical forensic evidence. The best practice is to investigate the issue while maintaining logs and memory captures for further analysis.
Option C: Deleting logs is a critical mistake. Security logs provide vital information for incident investigation, root cause analysis, and compliance reporting. Logs should be preserved and analyzed, not erased.
Option D: Proper incident response requires documenting the event in an incident report and escalating it through the Security Operations Center (SOC). CrowdStrike Falcon provides detailed logging, detections, and forensic tools that should be used to investigate before taking additional remediation actions.

Option A: This is correct because using the "Domain Name" condition type allows you to specify a particular domain as the target for the IOM rule. This ensures that CrowdStrike monitors and blocks activities related to the specified domain. Proper configuration of the condition type is essential for the rule to function as intended.
Option B: This is incorrect because "File Hash" is designed for identifying specific files based on their hash values, not for blocking domains or IP addresses. Using this type would result in an ineffective rule for domain blocking.
Option C: This is incorrect because the Allowlist is used to exclude entities from being flagged or blocked by CrowdStrike. Adding a domain to the Allowlist would prevent it from being blocked.
Option D: This is incorrect because severity levels such as "Informational" are used for categorizing the criticality of events, not for determining whether a rule will block activity. For blocking, the rule's action type must explicitly include "Block."

Option A: Cloud provider default settings don't automatically support CrowdStrike integration. You need to explicitly configure and register the registry with CrowdStrike.
Option B: While API keys may be used for other integrations, the process of registering a connection involves providing the registry's credentials to CrowdStrike, not the other way around.
Option C: Automatic image scanning by the registry itself doesn't integrate with CrowdStrike. You must explicitly connect the registry to CrowdStrike for its scanning capabilities to be utilized.
Option D: To establish a connection for image scanning, you need to register the image registry in the CrowdStrike Falcon console. This involves providing the registry's credentials and configuration details, enabling CrowdStrike to access and scan images securely. This step establishes trust and ensures compatibility between the registry and CrowdStrike.
