The Process Activity View provides a rows-and-columns style view of the events generated in a detection. Why might this be helpful?
Answer(s): A
According to the CrowdStrike Falcon Devices Add-on for Splunk Installation and Configuration Guide v3.1.5+, the Process Activity View allows you to view all events generated by a process involved in a detection in a rows-and-columns style view. This can be helpful because it creates a consolidated view of all detection events for that process that can be exported for further analysis. You can also sort, filter, and pivot on the events by various fields, such as event type, timestamp, file name, registry key, network destination, etc.
After running an Event Search, you can select many Event Actions depending on your results. Which of the following is NOT an option for any Event Action?
According to the CrowdStrike Falcon Devices Add-on for Splunk Installation and Configuration Guide v3.1.5+, the Event Search tool allows you to search for events based on various criteria, such as event type, timestamp, hostname, IP address, etc. You can also 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, etc. However, there is no option to draw a process explorer, which is a graphical representation of the process hierarchy and activity.
Which option indicates a hash is allowlisted?
Answer(s): B
According to the CrowdStrike 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 performance. 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.
Which of the following tactic and technique combinations is sourced from MITRE ATT&CK information?
Answer(s): D
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. Credential Access via OS Credential Dumping is an example of a tactic and technique combination sourced from MITRE ATT&CK information, which describes how adversaries can obtain credentials from operating system memory or disk storage by using tools such as Mimikatz or ProcDump.
What do IOA exclusions help you achieve?
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 activities. This can reduce false positives and improve performance. IOA exclusions only apply to IOA based detections, not other types of detections such as machine learning, custom IOA, or OverWatch.
