CrowdStrike CCFR-201 Based on Real Exam Environment

According to the CrowdStrike Falcon Devices Add-on for Splunk Installation and Configuration Guide v3.1.5+, the Bulk Domain Search tool allows you to search for one or more domains and view a summary of information from Falcon events that contain those domains2. The summary includes the hostname, sensor ID, OS, country, city, ISP, ASN, geolocation, process name, command line, and organizational unit of the host that performed a lookup of any of the domains in your search2. This can help you identify potential threats or vulnerabilities in your network2.

According to the CrowdStrike Falcon Devices Add-on for Splunk Installation and Configuration Guide v3.1.5+, the Hash Search tool allows you to search for one or more SHA256 hashes and view a summary of information from Falcon events that contain those hashes1. The summary includes the hostname, sensor ID, OS, country, city, ISP, ASN, geolocation, process name, command line, and organizational unit of the host that loaded or executed those hashes1. You can also see a count of detections and incidents related to those hashes1. The primary purpose for running a Hash Search is to review information surrounding a hash’s related activity, such as which hosts and processes were involved, where they were located, and whether they triggered any alerts1.

According to the CrowdStrike Falcon® Data Replicator (FDR) Add-on for Splunk Guide, IOA exclusions allow you to exclude files or directories from being detected or blocked by CrowdStrike’s indicators of attack (IOAs), which are behavioral rules that identify malicious activities2. This can reduce false positives and improve performance2. IOA exclusions only apply to IOA based detections, not other types of detections such as machine learning, custom IOA, or OverWatch2.

According to the [CrowdStrike Falcon® Data Replicator (FDR) Add-on for Splunk Guide], when you quarantine a file from a host using IOC Management or Real Time Response (RTR), you are moving it from its original location to a secure location on the host where it cannot be executed. The file is also encrypted and renamed with a random string of characters. A copy of the file is also uploaded to the CrowdStrike Cloud for further analysis. Quarantined files are stored in the CrowdStrike Cloud for 90 days before they are deleted.
