Free CrowdStrike Certified Falcon Responder CCFR-201b Exam Questions

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 organization2.This action also removes the file from the quarantine list and deletes it from the CrowdStrike Cloud2.

According to the [CrowdStrike Falcon Data Replicator (FDR) Add-on for Splunk Guide], when you open the full detection details from a detection alert or dashboard item, you are taken to a page where you can view detailed information about the detection, such as detection ID, severity, tactic, technique, description, etc. You can also view the events generated by the processes involved in the detection in different ways, such as process tree, process timeline, or process activity. The process tree view is also known as the process explorer, which provides a graphical representation of the process hierarchy and activity. You can view the processes and process relationships by expanding or collapsing nodes in the tree. You can also see the event types and timestamps for each process.

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.

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.You can also filter the events by various criteria, such as event type, timestamp range, file name, registry key, network destination, etc2.This is an advantage of using the Process Timeline tool because it allows you to focus on specific events that are relevant to your investigation2.

According to theCrowdStrike Falcon Devices Add-on for Splunk Installation and Configuration Guide v3.1.5+, Event Actions are automated searches that can be used to pivot between related events and searches1.They are available in various tools, such as Event Search, Process Timeline, Host Timeline, etc1.You can select one or more events and perform various actions, such as show a process timeline, show a host timeline, show associated event data, show a +/- 10-minute window of events, etc1.These actions can help you investigate and analyze events more efficiently and effectively1.

According to the [CrowdStrike website], the Discover page is where you can search for and analyze various types of indicators of compromise (IOCs), such as hashes, IP addresses, or domains that are associated with malicious activities. You can use various tools, such as Hash Executions, IP Addresses, Remote or Network Logon Activity, etc., to perform different types of searches and view the results in different ways. If you want to search for any activity related to an IP address that was compromised by a third-party vendor, you can use the IP Addresses tool to do so. You can input the IP address and see a summary of information from Falcon events that contain that IP address, such as hostname, sensor ID, OS, country, city, ISP, ASN, geolocation, process name, command line, and organizational unit of the host that communicated with that IP address.

According to theCrowdStrike Falcon Data Replicator (FDR) Add-on for Splunk Guide, the Always Block action allows you to block a file from executing on any host in your organization based on its hash value2.This action can be used to prevent known malicious files from running on your endpoints2.

According to theCrowdStrike Falcon Data Replicator (FDR) Add-on for Splunk Guide, the Falcon platform will show a maximum of 1000 detections per day for a single AID1.This is a limit imposed by the Falcon API, which is used to retrieve the detections from the CrowdStrike Cloud1.If there are more than 1000 detections per day for a single AID, only the first 1000 will be shown1.

According to the [CrowdStrike website], the MITRE-Based Falcon Detections Framework is a way of categorizing and describing detections based on the MITRE ATT&CK knowledge base of adversary behaviors and techniques. The framework uses three levels of granularity: category, tactic, and technique. The category is the highest level and represents the main objective of an adversary, such as initial access, execution, credential access, etc. The tactic is the second level and represents the sub-objective of an adversary within a category, such as persistence, privilege escalation, defense evasion, etc. The technique is the lowest level and represents the specific way an adversary can achieve a tactic, such as create account, modify registry, obfuscated files or information, etc. Therefore, the correct way to interpret Keep Access > Persistence > Create Account is that an adversary is trying to keep access through persistence by creating an account.

According to theCrowdStrike Falcon Devices Add-on for Splunk Installation and Configuration Guide v3.1.5+, the ParentProcessld_decimal field contains the decimal value of the process ID of the parent process that spawned or injected into the target process1.This field can be used to trace the process lineage and identify malicious or suspicious activities1.
