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 =

Onboarding data to Splunk Enterprise Security

Correlation searches are scheduled searches that run in Splunk Enterprise Security to detect security incidents or other notable events. They can consume a lot of resources and affect the overall search performance. To improve the search performance, you can do the following actions:

• Reduce the frequency (schedule) of lower-priority correlation searches. This will reduce the number of searches that run concurrently and free up some resources for other searches. You can edit the schedule of a correlation search in the Content Management page of Splunk Enterprise Security. See Edit a correlation search in Splunk Enterprise Security for more details.
• Add notable event suppressions for correlation searches with high numbers of false positives. This will prevent the correlation search from generating notable events that are not relevant or actionable, and reduce the load on the Notable Event Framework. You can add suppression rules for a correlation search in the Content Management page of Splunk Enterprise Security. See Suppress notable events in Splunk Enterprise Security for more details.

The other two actions are not recommended, because they can have negative effects on the search performance or the security posture. Disabling indexed real-time search can cause some dashboards and panels to not display data correctly, and increasing the priority of all correlation searches can cause resource contention and degrade the performance of other searches. See Optimize Splunk Enterprise for peak performance and How search types affect Splunk Enterprise performance for more information. References =

According to the Splunk Reference Architecture document1, for ES, Splunk recommends sizing based on 80 to 100 GB ingest per indexer per day. This means an ES deployment with 2 TB daily ingest will require up to 20 indexers. This recommendation is for a non-cloud (on-prem) ES deployment. For a cloud-based ES deployment, the recommended volume of indexing per day, per indexer, is 50 GB2. The other options, 300 GB and 500 MB, are not recommended by Splunk for ES deployments. References =

 The correct way to add a new lookup through the ES app is to upload the lookup file using Configure > Content Management > Create New Content > Managed Lookup. This allows the user to create or select an existing lookup file and definition, specify the lookup type, label, and description, and enable editing of the lookup file. This also stores the lookup file at the application level, which makes it easier to edit and share. The other options are either incorrect or not recommended for ES. Uploading the lookup file in Settings > Lookups > Lookup table files does not create a lookup definition or a label and description for the lookup. Uploading the lookup file in Settings > Lookups > Lookup Definitions does not upload the lookup file itself, but only creates a definition for an existing file. Adding the lookup file to /etc/apps/SplunkEnterpriseSecuritySuite/lookups requires manual editing of the file system and is not recommended for ES. References =

The tstatsHomePath setting in indexes.conf allows you to specify an alternate location for accelerated storage. Accelerated storage is where Splunk Enterprise stores the summary data for data models that are accelerated. The summary data is used to speed up searches and reports that use the data models. By default, the accelerated storage is located in the same volume as the index that contains the events referenced by the data model. However, you can use the tstatsHomePath setting to change the location of the accelerated storage to a different volume or path. This can help you optimize the performance and disk space usage of your Splunk Enterprise deployment. References =

• Use the tstatsHomePath setting in indexes.conf if you need to specify alternate locations for your accelerated storage

 According to the Splunk Enterprise Security documentation, the Status Configuration window allows you to customize the status values and transitions for notable events. You can define which roles can change the status of a notable event from one value to another, and which roles can view the notable events with a specific status. To restrict the users with the ess_user role from being able to change the status of Resolved notable events to closed, you need to do the following steps:

• On the Enterprise Security menu bar, select Configure > Incident Management > Status Configuration.
• In the Status Configuration window, select the Resolved status from the list of values.
• In the Status Transitions section, find the row for the closed status and click the Edit icon.
• In the Edit Status Transition dialog box, remove the ess_user role from the Roles field and click Save.
• Click Save Changes to apply the changes to the Status Configuration window.

This will prevent the users with the ess_user role from changing the status of any notable event from Resolved to closed. They will still be able to change the status of other notable events to closed, if they have the permission to do so. Therefore, the correct answer is A. From the Status Configuration window select the Resolved status. Remove ess_user from the status transitions for the closed status. References = Customize status values and transitions for notable events.

According to the Splunk Add-on Builder documentation, after managing source types and extracting fields, the key step that comes next in the Add-on Builder is to map to data models. Data models are predefined schemas that provide a common standard for organizing and naming data fields across different data sources. Splunk Enterprise Security uses the Splunk Common Information Model (CIM) to enable cross-source analysis and correlation of security events. The Add-on Builder helps you to map your data fields to the CIM data models, such as Authentication, Change, Endpoint, and others. You can use the Data Model Mapper tool to select the data models that are relevant to your data source and map the fields accordingly. You can also validate the data model mappings and preview the results. See Map to data models for more details.

The other options are not the correct steps that come next in the Add-on Builder. Validate and package is the last step in the Add-on Builder, where you can check the quality and readiness of your add-on and create a package file for distribution. See Validate and package for more details. Configure data collection is the first step in the Add-on Builder, where you can specify the method and parameters for collecting data from your data source. See Configure data collection for more details. Create alert actions is an optional step in the Add-on Builder, where you can build custom alert actions or adaptive response actions for Splunk Enterprise Security. See [Create alert actions] for more details. Therefore, the correct answer is D. Map to data models. References =

Glass tables can display static images and text, the results of ad-hoc searches, and security metrics. Security metrics are visualizations that show the values of KPIs, service health scores, or notable events. You can add security metrics to a glass table by using the Security Metrics menu in the glass table editor. You can also configure the appearance, behavior, and drilldown options of the security metrics. Glass tables cannot display lookup searches, summarized data, or metrics store searches directly, although you can use these types of searches as data sources for ad-hoc searches and then display the results on a glass table.

The Auto Deployment feature of Distributed Configuration Management is a tool that allows you to automatically distribute configuration files, such as indexes.conf, to your Splunk platform instances. However, using this feature to distribute indexes.conf can pose a risk of having indexes with different settings across your instances. This can happen if you have manually edited the indexes.conf file on some of your instances, or if you have different versions of Splunk Enterprise Security installed on different instances. If the indexes have different settings, such as retention policies, storage paths, or bucket sizes, this can cause data inconsistency, search inefficiency, or data loss. Therefore, it is recommended to use the Manual Deployment feature of Distributed Configuration Management to review and validate the indexes.conf file before deploying it to your instances12. References = 1: Distributed Configuration Management - Splunk Documentation - Auto Deployment. 2: Distributed Configuration Management - Splunk Documentation - Manual Deployment.

The Status Configuration window in Splunk Enterprise Security allows you to manage and customize the investigation statuses and the status transitions for notable events. You can specify which roles can change the status of a notable event from one status to another. For example, you can restrict the ess_user role from changing the status of Resolved notable events to Closed by removing the ess_user role from the status transitions for the Closed status. This way, only the roles that have the permission to change the status to Closed can close the Resolved notable events. References =

Detailed information about identities, such as user names, email addresses, phone numbers, and roles, is stored in the Identity Lookup CSV file in Splunk Enterprise Security. The Identity Lookup CSV file is a lookup file that contains the identity data that is collected and extracted from various data sources, such as Active Directory, LDAP, or custom identity lists. The Identity Lookup CSV file is used to enrich events with identity information and generate notable events based on identity correlation searches. You can view and manage the Identity Lookup CSV file using the Asset and Identity Management page in Splunk Enterprise Security. References =

 A prefix of Splunk_TA_ would allow an add-on to be automatically imported into Splunk Enterprise Security. Splunk Enterprise Security uses a naming convention to identify and import add-ons that are compatible with the Common Information Model (CIM). Add-ons that start with Splunk_TA_ are automatically imported into Splunk Enterprise Security and mapped to the appropriate data models. Add-ons that do not follow this naming convention must be manually imported and configured in Splunk Enterprise Security1. A prefix of CIM_ or TECH_ does not indicate an add-on that can be automatically imported. A suffix of .spl is the file extension for Splunk apps and add-ons, but it does not guarantee that they are compatible with Splunk Enterprise Security. References =

A key feature of a glass table is customization. A glass table is a dashboard that allows you to create dynamic and interactive visualizations of your security data. You can customize a glass table by adding static images and text, the results of ad-hoc searches, and security metrics that show the values of KPIs, service health scores, or notable events. You can also configure the appearance, behavior, and drilldown options of the glass table elements. A glass table is not rigid, but flexible and adaptable to your security needs. A glass table is not designed for interactive investigations, but for high-level monitoring and analysis. A glass table does not store data for later retrieval, but shows real-time data generated by KPIs and services. References =

Data integrity control is a feature of Splunk Enterprise that helps you verify the integrity of data that it indexes. When you enable data integrity control for an index, Splunk Enterprise computes hashes on every slice of data using the SHA-256 algorithm. It then stores those hashes so that you can verify the integrity of your data later. This feature prevents data tampering and ensures that the data is trustworthy and reliable. Therefore, the correct answer is B. Data integrity control. References = Manage data integrity - Splunk Documentation.

In order to include an eventtype in a data model node, you need to apply the correct tags to the eventtype. Tags are labels that you can assign to event types to identify them as belonging to a specific category or domain. Tags are used by data models to map event types to data model nodes. For example, if you have an eventtype named windows_performance that contains events related to Windows performance metrics, you can tag it with performance and os. Then, you can include the eventtype in a data model node that matches those tags, such as the Performance node in the Operating System data model12. To apply tags to an eventtype, you can use the Settings > Event types page in Splunk Web, or the eventtypes.conf and tags.conf configuration files3. References = 1: About data models - Splunk Documentation - How data models use tags. 2: Use tags to map event types to data model nodes - Splunk Documentation. 3: About event types - Splunk Documentation - Tag event types.

A field alias is a knowledge object that maps a non-standard field name to a CIM field name. A field alias allows you to use the same search string to retrieve data from different data sources, even if the data sources use different field names for the same type of data. For example, if you have data sources that use different field names for the source IP address, such as src_ip, source_ip, or sip, you can create a field alias that maps these field names to the CIM field name src. This way, you can use src as a common field name in your searches and reports, and Splunk will automatically replace it with the appropriate field name for each data source. Field aliases are applied at search time, so they do not affect the original data or the index time field extractions. References =

Onboarding data to Splunk Enterprise Security

The endpoint security domain dashboards in Splunk Enterprise Security display endpoint data relating to malware infections, patch history, system configurations, and time synchronization information. The sources for events in the endpoint security domain dashboards are the devices that are considered endpoints in your network, such as workstations, notebooks, and point-of-sale systems1. References = 1: Introduction to the dashboards available in Splunk Enterprise Security - Endpoint domain dashboards.

The value in the red box is an IP address rating. This is a numerical value that represents the risk associated with an IP address. The higher the value, the higher the risk. This value is calculated based on the number of security events associated with the IP address, the severity of those events, and the time since the last event. References:

 The Remote Access panel within the User Activity dashboard is based on the Authentication data model, which contains information about authentication events from various sources, such as VPN, SSH, RDP, and others. The Authentication data model is accelerated by default, which means that it generates summary data to speed up searches. However, if the summary data is not up to date, the dashboard panel may not show the most recent data. This can happen if the data model acceleration search is skipped, disabled, or encountering errors12. To check the status of the data model acceleration, you can use the Data Model Audit dashboard in the Monitoring Console3 or the | datamodel command in the Search app4. References = 1: User Activity Monitoring - Splunk Documentation - Remote Access. 2: About data model acceleration - Splunk Documentation. 3: Use the Data Model Audit dashboard - Splunk Documentation. 4: datamodel - Splunk Documentation.

The setting that is used in indexes.conf to specify alternate locations for accelerated storage is tstatsHomePath. Accelerated storage is the location where Splunk Enterprise stores the summary data for accelerated data models and reports. By default, acceleration storage is allocated in the same location as the index containing the raw events being accelerated. However, if you need to specify alternate locations for your accelerated storage, you can use the tstatsHomePath setting in indexes.conf. This setting allows you to define a different path for the summary data, which can improve the performance and efficiency of the data model acceleration. For example, you can set the tstatsHomePath to a faster disk or a different volume than the index homePath12. References = 1: Managing data models in Enterprise Security - Splunk Lantern - Indexes allow list. 2: indexes.conf - Splunk Documentation - tstatsHomePath.

The correct answer is B. Normalize data. The Add-on Builder can configure a new add-on to normalize data by mapping the data fields to the Common Information Model (CIM). The CIM provides a common language for describing data across domains and technologies. Normalizing data enables the data to be used by other Splunk apps, such as Splunk Enterprise Security and Splunk IT Service Intelligence. The Add-on Builder can also configure other features in a new add-on, such as collecting data from various sources, extracting fields from the data, creating alert actions and adaptive response actions, and testing and validating the add-on. However, the Add-on Builder cannot configure an add-on to expire data, summarize data, or translate data. These are not features of the Add-on Builder. References =

 According to the Splunk Enterprise Security documentation, the bar across the bottom of any ES window is called the Investigation Bar. The Investigation Bar is a tool that helps you create and manage investigations in ES. An investigation is a collection of related notable events, comments, and artifacts that document a security incident or a threat hunting activity. You can use the Investigation Bar to do the following tasks:

• Create a new investigation or open an existing one.
• Add notable events, comments, and artifacts to an investigation.
• Assign an owner and a status to an investigation.
• Share an investigation with other users or roles.
• Export an investigation as a PDF report.

The Investigation Bar also provides a link to the Investigation Workbench, which is a dashboard that shows a timeline and a summary of an investigation. Therefore, the correct answer is B. The Investigation Bar. References = Use the Investigation Bar.

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

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 =

 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 =

The Risk Analysis dashboard uses the Risk data model to populate the panels. The Risk data model is a data model that contains information about the risk scores and risk modifiers of various objects, such as systems, users, hashes, and network artifacts. The Risk data model accelerates these fields for the Risk Analysis and Incident Review dashboards. The Risk data model also handles case insensitive asset and identity correlation, allowing risk modifiers that are applied to system or user name variants to be correctly attributed to the same risk_object1. The other options, B, C, and D, are not correct. The Audit data model contains information about audit events, such as user logins, password changes, and system access. The Domain Analysis data model contains information about the domains that are visited by the systems in the network. The Threat Intelligence data model contains information about the threat intelligence sources, indicators, and matches. References =
