Which option indicates a hash is allowlisted?
According to theCrowdStrike Falcon Data Replicator (FDR) Add-on for Splunk Guide, the allowlist feature allows you to exclude files or directories from being scanned or blocked by CrowdStrike's machine learning engine or indicators of attack (IOAs)2.This can reduce false positives and improve performance2.When you allowlist a hash, you are allowing that file to execute on any host that belongs to your organization's CID (customer ID)2.The option to indicate that a hash is allowlisted is 'Allow'2.
You are reviewing the raw data in an event search from a detection tree. You find a FileOpenlnfo event and want to find out if any other files were opened by the responsible process. Which two field values do you need from this event to perform a Process Timeline search?
According to theCrowdStrike Falcon Devices Add-on for Splunk Installation and Configuration Guide v3.1.5+, the Process Timeline tool allows you to view all cloudable events associated with a given process, such as process creation, network connections, file writes, registry modifications, etc2.The tool requires two parameters:aid(agent ID) andTargetProcessId_decimal(the decimal value of the process ID)2.These fields can be obtained from any event that involves the process, such as a FileOpenInfo event, which contains information about a file being opened by a process2.
What is an advantage of using the IP Search tool?
According to theCrowdStrike Falcon Devices Add-on for Splunk Installation and Configuration Guide v3.1.5+, the IP Search tool allows you to search for an IP address and view a summary of information from Falcon events that contain that IP address1.The summary includes the hostname, sensor ID, OS, country, city, ISP, ASN, geolocation, process name, command line, and organizational unit of the host that communicated with that IP address1.This is an advantage of using the IP Search tool because it provides host, process, and organizational unit data without the need to write a query1.
When looking at the details of a detection, there are two fields called Global Prevalence and Local Prevalence. Which answer best defines Local Prevalence?
According to theCrowdStrike Falcon Devices Add-on for Splunk Installation and Configuration Guide v3.1.5+, Global Prevalence and Local Prevalence are two fields that provide information about how common or rare a file is based on its hash value2.Global Prevalence tells you how frequently the hash of the triggering file is seen across all CrowdStrike customer environments2.Local Prevalence tells you how frequently the hash of the triggering file is seen within your environment (CID)2.These fields can help you assess the risk and impact of a detection2.
What happens when a quarantined file is released?
According to theCrowdStrike Falcon Data Replicator (FDR) Add-on for Splunk Guide, when you release a file from quarantine, you are restoring it to its original location and allowing it to execute on any host in your organization1.This action also removes the file from the quarantine list and deletes it from the CrowdStrike Cloud1.
