How can a Falcon Administrator configure a pop-up message to be displayed on a host when the Falcon sensor blocks, kills or quarantines an activity?
A Falcon Administrator can configure a pop-up message to be displayed on a host when the Falcon sensor blocks, kills or quarantines an activity by turning on the ''Notify End Users'' setting at the top of the Prevention policy details configuration page. This setting allows users to enable or disable end user notifications for prevention actions taken by Falcon on Windows hosts. The other options are either incorrect or not related to configuring pop-up messages. Reference:CrowdStrike Falcon User Guide, page 36.
You are attempting to install the Falcon sensor on a host with a slow Internet connection and the installation fails after 20 minutes. Which of the following parameters can be used to override the 20-minute default provisioning window?
'ProvNoWait=1
The sensor does not abort installation if it can't connect to the CrowdStrike cloud within 20 minutes (10 minutes, in Falcon sensor version 6.21 and earlier). (By default, if the host can't contact our cloud, it will retry the connection for 20 minutes. After that, the host will automatically uninstall its sensor.)'
'ProvWaitTime=3600000
The sensor waits for 1 hour to connect to the CrowdStrike cloud when installing (the default is 20 minutes).'
You have an existing workflow that is triggered on a critical detection that sends an email to the escalation team. Your CISO has asked to also be notified via email with a customized message. What is the best way to update the workflow?
The best way to update the workflow is to add a parallel action to send a custom email to your CISO. A parallel action allows you to perform multiple actions simultaneously when a workflow is triggered, without affecting the order or outcome of other actions. A sequential action, on the other hand, requires one action to complete before another action can start.By adding a parallel action, you can ensure that both the escalation team and your CISO receive an email notification as soon as possible1.
Which role allows a user to connect to hosts using Real-Time Response?
The role that allows a user to connect to hosts using Real-Time Response is Real Time Responder -- Active Responder. This role allows users to use the ''Connect to Host'' feature to gather additional information from the host, as well as execute commands and scripts on the host. The other roles do not have this capability. Reference: [CrowdStrike Falcon User Guide], page 18.
What is likely the reason your Windows host would be in Reduced Functionality Mode (RFM)?
The likely reason your Windows host would be in Reduced Functionality Mode (RFM) is that the host lost internet connectivity. RFM is a mode that limits the sensor's functionality due to license expiration, network connectivity loss, or certificate validation failure. When a Windows sensor is in RFM, it will only provide basic prevention capabilities, such as blocking known malware hashes and preventing script execution from the %TEMP% directory.The sensor will not send any telemetry or detection events to the Falcon platform, and will not receive any policy or update changes from the Falcon cloud1. Losing internet connectivity is a common cause of RFM, as it prevents the sensor from communicating with the Falcon cloud. A misconfiguration in your prevention policy or sensor update policy will not cause RFM, as these policies are applied by the Falcon cloud and do not affect the sensor's license, network, or certificate status.Microsoft updates altering the kernel may cause compatibility issues with the sensor, but not RFM3.
