Where would an analyst find information about shells spawned by root, Kernel Module loads, and wget/curl usage?
The Linux Sensor report is where an analyst would find information about shells spawned by root, Kernel Module loads, and wget/curl usage. The Linux Sensor report is a pre-defined report that provides a summary view of selected activities on Linux hosts. It shows information such as process execution events, network connection events, file write events, etc. that occurred on Linux hosts within a specified time range. The Sensor Health report, the Sensor Policy Daily report, and the Mac Sensor report do not provide the same information.
What kind of activity does a User Search help you investigate?
User Search is an Investigate tool that helps you investigate a list of process activity executed by the specified user account. It shows information such as process name, command line, parent process name, parent command line, etc. for each process that was executed by the user account on any host in your environment. It does not show a history of Falcon UI logon activity, a count of failed user logon activity, or a list of DNS queries by the specified user account.
Which field in a DNS Request event points to the responsible process?
The ContextProcessld_readable field in a DNS Request event points to the responsible process. The ContextProcessld_readable field is the readable representation of the process identifier for the process that initiated the DNS request. It can be used to identify which process was communicating with a specific domain or IP address. The TargetProcessld_decimal, ContextProcessld_decimal, and ParentProcessId_decimal fields do not point to the responsible process.
You want to produce a list of all event occurrences along with selected fields such as the full path, time, username etc. Which command would be the appropriate choice?
The table command is used to produce a list of all event occurrences along with selected fields such as the full path, time, username etc. It takes one or more field names as arguments and displays them in a tabular format. The fields command is used to keep or remove fields from search results, not to display them in a list. The distinct_count command is used to count the number of distinct values of a field, not to display them in a list. The values command is used to display a list of unique values of a field within each group, not to display all event occurrences.
Adversaries commonly execute discovery commands such as netexe, ipconfig.exe, and whoami exe. Rather than query for each of these commands individually, you would like to use a single query with all of them. What Splunk operator is needed to complete the following query?

The OR operator is needed to complete the following query, as it allows to search for events that match any of the specified values. The query would look like this:
event_simpleName=ProcessRollup2 FileName=net.exe OR FileName=ipconfig.exe OR FileName=whoami.exe
The OR operator is used to combine multiple search terms or expressions and return events that match at least one of them. The IN, NOT, and AND operators are not suitable for this query, as they have different functions and meanings.
