Pass SPLK-3001 Exam Guide

According to the Splunk Enterprise Security documentation, one of the actions that may be necessary before installing ES is to redirect distributed search connections. This action is required if you are installing ES on a search head that is already connected to a distributed search environment, such as a search head cluster or a search head pool. You need to redirect the distributed search connections from the existing search head to a new search head that will run ES. This is because ES requires a dedicated search head that is not shared with other apps or users. You can use the Distributed Configuration Management tool to redirect the distributed search connections and create a Splunk Enterprise Security app for indexers. See Redirect distributed search connections for more details.

The other actions are not necessary before installing ES, but they may be helpful for optimizing the performance and scalability of ES. Purging KV Store can free up some disk space and remove stale data, but it is not required before installing ES. See Purge the KV Store for more information. Adding additional indexers can improve the indexing and searching capacity of ES, but it is not required before installing ES. See Deployment planning for more information. Adding additional forwarders can increase the data ingestion and forwarding capability of ES, but it is not required before installing ES. See Forward data to Splunk Enterprise Security for more information. References =

 According to the Splunk Enterprise Security documentation, the Default Account Activity Detected correlation search uses the Local User Intel lookup table to flag known default accounts. The Local User Intel lookup table contains a list of default usernames and passwords for various systems and applications, such as admin, root, guest, and others. The correlation search compares the authentication events from the Authentication data model with the usernames in the lookup table and generates a notable event if there is a match. The notable event indicates that a default account was used to access a system or application, which could be a sign of a brute force attack or a misconfiguration. Therefore, the correct answer is B. Local User Intel. References =

• Default Account Activity Detected
• Local User Intel

Splunk Enterprise Security requires a dedicated search head with no other apps installed. This is because ES is a resource-intensive application that may cause performance issues and conflicts with other apps. Installing ES on a search head with other apps may also result in data loss or corruption. Therefore, it is recommended to install ES on a clean search head with only the default built-in apps and the Common Information Model (CIM) app. The CIM app is a prerequisite for ES and provides a common language for describing data across domains and technologies. The other options, B, C, and D, are not correct. Installing ES on a search head with any other apps, including TA-* or CIM-compliant apps, is not supported and may cause problems. References =

The argument to the | tstats command that restricts the search to summarized data only is summariesonly=t. Summarized data is the data that is generated by the data model acceleration process, which creates summary indexes (TSIDX files) for the data models. By using summariesonly=t, the tstats command will only search the summary indexes, which can improve the performance and efficiency of the search. However, this also means that the search will not return any events that are not covered by the data model acceleration, such as events outside the acceleration time range or events that do not match the data model constraints12. References = 1: tstats - Splunk Documentation - summariesonly. 2: Managing data models in Enterprise Security - Splunk Lantern - Indexes allow list.
