Helping Hand Questions for SPLK-5001

The examples provided correspond to Tactics, Techniques, and Procedures (TTPs) in the following order:

Lateral movement– This is aTactic. Tactics represent the goals or objectives of an adversary, such as moving laterally within a network to gain broader access.

Exploiting a remote service– This is aTechnique. Techniques are specific methods used to achieve a tactic, such as exploiting a service to move laterally.

Use EternalBlue to exploit a remote SMB server– This is aProcedure. Procedures are the detailed steps or specific implementations of a technique, such as using the EternalBlue exploit to target SMB vulnerabilities.

Thus, the correct order isTactic, Technique, Procedure.

In Splunk,streaming commandsprocess each event individually as it is passed through the search pipeline and should be placed beforeaggregating commands, which operate on the entire set of results at once. This best practice ensures efficient processing and minimizes resource usage, as streaming commands reduce the amount of data before aggregation occurs. This approach leads to faster and more efficient searches. In contrast, the other options, such as using wildcards excessively or searching over all time, can lead to performance issues and excessive data processing.

NetFlow data is a powerful data source for monitoring and analyzing network traffic patterns within an organization. It provides detailed information about the flow of data between devices on a network, including source and destination IP addresses, ports, and protocols. By analyzing NetFlow data, security analysts can detect unusual communication patterns that may indicate malicious activity, such as lateral movement, data exfiltration, or communication with command and control servers. Other options like EDS (Endpoint Detection Systems), Email, and IAM (Identity and Access Management) are also valuable, but NetFlow is specifically designed for network traffic analysis.

Themakeresultscommand in Splunk is used to generate a single-row result that can be used to create test data within a search pipeline. This command is particularly useful for testing and experimenting with SPL commands on a small set of synthetic data without relying on existing logs or events in the Splunk index. It is commonly used by analysts who want to test commands or SPL syntax before applying them to real data.
