Free CrowdStrike CCFR-201 Practice Exam with Questions & Answers

According to the CrowdStrike 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.

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® 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 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 the CrowdStrike 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, etc1. You can specify a timeframe to limit the events to a certain period1. The tool works for any host platform, not just Mac or Linux1.

According to the CrowdStrike Falcon® Data Replicator (FDR) Add-on for Splunk Guide, you can use the Hosts page in the Investigate tool to view information about your endpoints, such as hostname, IP address, OS, sensor version, etc2. You can also see a list of managed and unmanaged neighbors for each endpoint, which are other devices that have communicated with that endpoint over the network2. This can help you identify potential threats or vulnerabilities in your network2.

According to the [MITRE ATT&CK website], MITRE ATT&CK is a knowledge base of adversary behaviors and techniques based on real-world observations. The knowledge base is organized into tactics and techniques, where tactics are the high-level goals of an adversary, such as initial access, persistence, lateral movement, etc., and techniques are the specific ways an adversary can achieve those goals, such as phishing, credential dumping, remote file copy, etc. The knowledge base also covers different platforms that adversaries target, such as Windows, Linux, Mac, Android, iOS, etc., and different phases of an adversary’s lifecycle, such as reconnaissance, resource development, execution, command and control, etc.

According to the CrowdStrike Falcon Devices Add-on for Splunk Installation and Configuration Guide v3.1.5+, Reduced Functionality Mode (RFM) is a state where a host’s sensor has limited functionality due to various reasons, such as license expiration, network issues, tampering attempts, etc1. You can find hosts that are in RFM by using the Host Search tool and filtering by Sensor Status = RFM1. You can also view details about why a host is in RFM by clicking on its hostname1.

According to the CrowdStrike Falcon Devices Add-on for Splunk Installation and Configuration Guide v3.1.5+, the ContextProcessld_decimal field contains the decimal value of the process ID of the process that generated the event1. This field can be used to trace the process lineage and identify malicious or suspicious activities1. For a DNS request event, this field indicates which process made the DNS request1.

According to the CrowdStrike 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.
