A technology add-on (TA) is a Splunk app that contains the configurations for ingesting and normalizing data from a specific data source or vendor. A TA can include sourcetype definitions, index-time and search-time field extractions, event types, tags, lookups, and other settings that help to map the data to the Splunk Common Information Model (CIM). The CIM is a set of predefined data models that provide a common standard for organizing and naming data fields across different data sources. Splunk Enterprise Security uses the CIM to enable cross-source analysis and correlation of security events. Therefore, the correct answer is D. Technology add-on. References =

The Add-On Builder is available from SplunkBase, which is the official source of apps and add-ons for the Splunk platform. SplunkBase allows you to browse, download, and install apps and add-ons that are compatible with your Splunk deployment. You can also upload and share your own apps and add-ons with the Splunk community. The Add-On Builder is a Splunk app that helps you build and validate technology add-ons for your Splunk Enterprise deployment. Technology add-ons are specialized add-ons that help to collect, transform, and normalize data feeds from specific sources in your environment. The Add-On Builder guides you through the process of creating an add-on, following best practices and naming conventions, maintaining CIM compliance, and testing and validating the add-on1. The Add-On Builder is not available from GitHub, www.splunk.com, or the ES installation package. References =

Adaptive responses are actions that can be performed in response to notable events or other security incidents. Adaptive responses can be triggered by correlation searches and users on the incident review dashboard. Correlation searches are scheduled searches that run periodically to detect patterns of interest in the data and generate notable events or other actions when the search conditions are met. Users can configure correlation searches to trigger adaptive responses automatically when a notable event is created. Users can also run adaptive responses manually from the incident review dashboard, which displays the notable events and their details. Users can select one or more notable events and choose an adaptive response action from the menu. Adaptive responses can help users to gather information, modify the environment, or take other actions to investigate and respond to security incidents. References =

The Splunk Add-on Builder helps you create technology add-ons, which are specialized add-ons that help to collect, transform, and normalize data feeds from specific sources in your environment. Technology add-ons are often referred to as TAs, and they start with the prefix TA-12. References = 1: Splunk Add-on Builder User Guide - About the Splunk Add-on Builder 2: Splunk Developer Portal - Develop Splunk Apps

By default, the CIM data models search all indexes in Splunk Enterprise Security. This means that any event that matches the tags and fields of a data model can be included in the data model, regardless of the index where it is stored. However, this can also affect the performance and efficiency of the data model searches, especially if there are many indexes that do not contain relevant data for the data model. Therefore, it is recommended to use the indexes allow list setting in the CIM add-on to constrain the indexes that each data model searches. The indexes allow list is a comma-separated list of indexes that you want to include in the data model search. You can specify index names or index macros. For example, you can set the indexes allow list for the Authentication data model to index=main, index=security, index=auth to limit the search to only those three indexes12. References = 1: Managing data models in Enterprise Security - Splunk Lantern - Indexes allow list. 2: Overview of the Splunk Common Information Model - Splunk Documentation - Why the CIM exists.

According to the Splunk Enterprise Security documentation, one of the recommended pre-installation steps is to configure search head forwarding. Search head forwarding is a feature that allows the search head to forward its internal logs and metrics to an indexer or a heavy forwarder for indexing and analysis. This feature helps you monitor the health and performance of the search head and troubleshoot any issues that may arise. You can configure search head forwarding by editing the outputs.conf file on the search head and specifying the destination indexer or forwarder. See Configure search head forwarding for more details.

The other options are not recommended, because they are either unnecessary or harmful for the installation of ES. Disabling the default search app is not a good option, because it may cause some features of ES to not work properly, such as the Content Management page and the navigation editor. Downloading the latest version of KV Store from MongoDB.com is not a good option, because ES uses the built-in KV Store service that comes with Splunk Enterprise and does not require any external installation or configuration. Installing the latest Python distribution on the search head is not a good option, because it may cause compatibility issues with ES, which uses the Python version that comes with Splunk Enterprise. Therefore, the correct answer is B. Configure search head forwarding. References = Configure search head forwarding.

According to the Splunk Enterprise Security documentation, an asset is a physical or logical device that is part of your network infrastructure, such as a server, a workstation, a router, or a firewall. An asset can have various attributes, such as IP address, MAC address, DNS name, NT host name, priority, business unit, owner, and others. Splunk Enterprise Security uses asset data to enrich and correlate security events and provide context for analysis. You can manage asset data using the Asset and Identity Management page in Splunk Enterprise Security. See Manage assets and identities in Splunk Enterprise Security for more details.

The other options are not examples of ES assets, but they may be related to other types of data. A MAC address is an attribute of an asset, not an asset itself. A user name is an example of an identity, which is a person or group that is associated with an asset or an event. Splunk Enterprise Security uses identity data to enrich and correlate security events and provide context for analysis. You can manage identity data using the Asset and Identity Management page in Splunk Enterprise Security. See Manage assets and identities in Splunk Enterprise Security for more details. People is a data model in the Splunk Common Information Model (CIM), which provides a common standard for organizing and naming data fields across different data sources. Splunk Enterprise Security uses the CIM to enable cross-source analysis and correlation of security events. The People data model contains the fields and tags for events that are related to people, such as user names, email addresses, phone numbers, and others. See People for more details. Therefore, the correct answer is C. Server. References =

Attachments to investigations are stored in a KV Store collection named investigation_attachment. KV Store is a feature that stores and manages data as key-value pairs. Splunk Enterprise Security uses KV Store to store investigation information in several collections, such as investigation, investigation_event, investigation_lead, and investigation_attachment. You can view or modify the KV Store collections using the KV Store API endpoint. For details about using the KV Store API endpoint, see KV Store endpoint descriptions in the Splunk Enterprise REST API Reference Manual1. The other options, B, C, and D, are not correct. Attachments to investigations are not stored in the notable index, the attachments.csv lookup, or the /etc/apps/SA-Investigations/default/ui/views/attachments directory. 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.
