CrowdStrike CCFR-201 Dumps

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, etc2. The tool requires two parameters: aid (agent ID) and TargetProcessId_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.

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 domains1. The summary includes the domain name, IP address, country, city, ISP, ASN, geolocation, hostname, sensor ID, OS, process name, command line, and organizational unit of the host that communicated with those domains1. This means that the tool contains domain information along with IP lookup information1.

According to the CrowdStrike Falcon Devices Add-on for Splunk Installation and Configuration Guide v3.1.5+, there are three ways to export process event data from a detection in .CSV format1:

• You can use the Process Timeline tool and click on “Export CSV” button at the top right corner1.
• You can use the Event Search tool and select one or more events and click on “Export CSV” button at the top right corner1.
• You can use the Full Detection Details tool and choose the “View Process Activity” option from any process node in the process tree view1. This will show you all events generated bythat process in a rows-and-columns style view1. You can then click on “Export CSV” button at the top right corner1.

According to the CrowdStrike Falcon® Data Replicator (FDR) Add-on for Splunk Guide, quarantined files are never deleted from the host unless you manually delete them or release them from quarantine2. 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 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.

According to the CrowdStrike Falcon Devices Add-on for Splunk Installation and Configuration Guide v3.1.5+, a DNSRequest event contains information about a DNS query made by a process2. The event has several fields, such as DomainName, QueryType, QueryResponseCode, etc2. The field that links a DNSRequest event to its responsible process is ContextProcessId_decimal, which contains the decimal value of the process ID of the process that generated the event2. You can use this field to trace the process lineage and identify malicious or suspicious activities2.

According to the [CrowdStrike Falcon® Data Replicator (FDR) Add-on for Splunk Guide], Sensor Visibility Exclusions allow you to exclude files or directories from being monitored by the sensor. This can reduce the amount of data sent to the CrowdStrike Cloud and improve performance. Sensor Visibility Exclusion patterns are written in Glob Syntax, which is a simple pattern matching syntax that supports wildcards, such as *, ?, and . For example, you can use *.exe to exclude all files with .exe extension.

According to the CrowdStrike Falcon® Data Replicator (FDR) Add-on for Splunk Guide, IOC Management allows you to manage indicators of compromise (IOCs), which are artifacts such as hashes, IP addresses, or domains that are associated with malicious activities2. You can set different actions for IOCs, such as Allow, No Action, or Always Block2. When you set a hash to Always Block through IOC Management, you are preventing that file from executing on any host in your organization by default2. This action also generates a detection alert when the file is blocked2.

According to the CrowdStrike Falcon Devices Add-on for Splunk Installation and Configuration Guide v3.1.5+, the Host Timeline tool allows you to view all events recorded by the sensor for a given host in a chronological order1. The events include process executions, file writes, registry modifications, network connections, user logins, etc1. You can use various filters to narrow down the events based on criteria such as event type, timestamp range, file name, registry key, network destination, etc1. However, there is no filter for severity, user name, or detection ID, as these are not attributes of the events1.

According to the CrowdStrike 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.

According to the CrowdStrike 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 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® 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 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. A managed neighbor is a device that has an installed and provisioned sensor that reports to the CrowdStrike Cloud2. An unmanaged neighbor is a device that does not have an installed or provisioned sensor2.

According to the CrowdStrike Falcon® Data Replicator (FDR) Add-on for Splunk Guide, the Detections page allows you to view and manage detections generated by the CrowdStrike Falcon platform2. You can use various filters to narrow down the detections based on criteria such as severity, CrowdScore, time, tactic, technique, etc2. However, there is no filter for triggering file, which is the file that caused the detection2.
