The administrator can modify settings to permit certain traffic during a containment period by creating or editing a Containment Policy. This policy allows users to specify which ports, protocols and IP addresses are allowed or blocked during network containment. The other options are either incorrect or not related to network containment. Reference: [CrowdStrike Falcon User Guide], page 40.

The report that can be used to determine if Script Based Execution Monitoring (SBEM) is not enabled on a Falcon host due to an old prevention policy is Prevention Policy Debug. The Prevention Policy Debug report allows you to view and compare the prevention policy settings applied to each host in your environment. You can use this report to identify any hosts that have outdated or inconsistent prevention policy settings, such as SBEM, which is a feature that monitors and prevents malicious script execution on Windows systems1.

The administrator can choose a specific sensor version number in the Sensor Update policy to manually control when the sensor version is upgraded or downgraded. This will allow the Falcon Cloud to push out sensor version changes, but only when the administrator changes the version number in the policy. The other options will either automate the sensor version updates or turn them off completely. Reference: [CrowdStrike Falcon User Guide], page 38.
