Splunk SPLK-3001 Dumps

 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 =

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 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

 ES apps and add-ons from $SPLUNK_HOME/etc/apps should be copied from the staging instance to the $SPLUNK_HOME/etc/shcluster/apps location on the cluster deployer instance. This is the directory where the deployer stores the configuration bundle that it distributes to the search head cluster members. The configuration bundle consists of apps and other configuration files that are not replicated by the cluster. The deployer does not use the $SPLUNK_HOME/etc/master-apps/ directory, which is used by the master node in an indexer cluster. The deployer does not use the $SPLUNK_HOME/etc/system/local/ directory, which is used to store local configuration files for the deployer instance itself. The deployer does not use the $SPLUNK_HOME/var/run/searchpeers/ directory, which is used by the search head to store information about the indexer cluster peers. References =

 This is because ES is a resource-intensive application that requires a dedicated search head with sufficient CPU and memory. Installing ES on the existing search head may cause performance issues and conflicts with other applications. Deleting the non-CIM-compliant apps from the search head is not recommended, as they are mission-critical for the site. Increasing the number of CPUs and amount of memory on the search head may not be enough to handle the load of ES and other applications. Therefore, option B is the most suitable answer. You can find more information about installing ES on this web page1.

 The urgency of a notable event is a value that indicates how important or urgent the event is for investigation and response. The urgency of a notable event is determined by two fields: the priority and the severity. The priority is a value that is assigned to an asset or an identity based on how critical or valuable it is for the organization. The priority can be unknown, low, medium, high, or critical. The severity is a value that is assigned to a notable event based on how serious or harmful the event is for the security posture. The severity can be unknown, informational, low, medium, high, or critical. The urgency of a notable event is calculated by combining the priority and the severity values using a lookup table called urgency_lookup. The urgency can be informational, low, medium, high, or critical. You can use the urgency field to prioritize the investigation of notable events in Splunk Enterprise Security. References =

To observe what network services are in use in a network’s activity overall, the Protocol Analysis dashboard in Enterprise Security will contain the most relevant data. The Protocol Analysis dashboard shows the network traffic data by protocol, such as TCP, UDP, ICMP, and others. You can use this dashboard to identify the most active protocols, the most active hosts, the most active ports, and the most active connections in your network. You can also filter the dashboard by protocol, host, port, or connection to narrow down your analysis. The Protocol Analysis dashboard uses the data from the Network Resolution (stream) data model, which requires the Splunk Stream app to collect network packet data1.

The ES application should be uploaded to the search head, which is the component that runs the ES user interface and executes the searches, alerts, and reports. The search head should be dedicated to ES and not run any other applications. The indexer is the component that indexes the data and stores it in buckets. The KV Store is a feature that stores and manages data as key-value pairs. The dedicated forwarder is a component that collects data from various sources and forwards it to the indexer. None of these components can run the ES application. References =

 The Threat Download Manager is a feature of Splunk Enterprise Security that downloads threat intelligence data from a web server. The Threat Download Manager is a modular input that runs on a schedule and fetches threat intelligence data from various sources, such as STIX/TAXII servers, RSS feeds, or custom URLs. The Threat Download Manager then passes the downloaded data to the Threat Intelligence Parser for further processing12. References = 1: Add threat intelligence to Splunk Enterprise Security - Splunk Documentation - Configure the threat intelligence sources included with Splunk Enterprise Security. 2: Using threat intelligence in Splunk Enterprise Security - Splunk Lantern - Where do I get threat intelligence?

The priority column in the asset or identity list is combined with the event severity to make a notable event’s urgency in Splunk Enterprise Security. The urgency is a measure of how important it is to address a notable event, and it is calculated based on a matrix that maps the priority of the asset or identity involved in the event and the severity of the event. The urgency can be one of the following values: low, medium, high, or critical12. For example, by default, medium, high, and critical priority, combined with critical severity, will generate a critical urgency ranking3. References = 1: Incident Review - Splunk Documentation - Urgency. 2: Configure notable event urgency - Splunk Documentation. 3: Solved: Splunk Enterprise Security: Is there a way to forc… - Splunk Community.

If the number of failed logins is greater than or equal to the threshold value, the search triggers a notable event. To make the search less sensitive, the threshold value can be increased, so that only more frequent failed logins will trigger a notable event. For example, the default threshold value is 4, which means that 4 or more failed logins within a 1-minute window will trigger a notable event. If the threshold value is changed to 10, then only 10 or more failed logins within a 1-minute window will trigger a notable event. References =

When exporting and importing updates to ES content, you should follow the best practices described in the Splunk Enterprise Security Admin documentation1. One of the best practices is to avoid overwriting existing content on the destination system. To do this, you have two options: either use new app names each time you export content, or always include both existing and new content in each export. This way, you can preserve the original content and avoid conflicts or data loss. The other options, A, B, and C, are not correct. Using new app names each time content is exported is only one of the options, not the only one. Using the .spl extension when naming an export is not a problem, as it is the default extension for Splunk apps. Including only new content for each export is not a good practice, as it may overwrite existing content on the destination system. References =

According to the Splunk Enterprise Security documentation, the Protocol Intelligence dashboards are the dashboards that support the ability to view and analyze network Stream data. The Protocol Intelligence dashboards provide a summary of network traffic by protocol, such as TCP, UDP, ICMP, and others. They also show the top sources, destinations, ports, and applications for each protocol. The dashboards allow you to filter the data by time range, protocol, source, destination, port, and application. The dashboards also provide drilldown links to other dashboards, such as the Network Resolution dashboard and the Traffic Size Analysis dashboard, for further analysis. The Protocol Intelligence dashboards require the Splunk App for Stream and the Splunk Add-on for Stream to capture and parse network traffic data. Therefore, the correct answer is C. Protocol Intelligence dashboards. References = Protocol Intelligence dashboards.

Splunk Enterprise Security supports downloading threat intelligence from STIX/TAXII servers. STIX is a structured language for describing cyber threat information, and TAXII is a protocol for exchanging STIX data. Splunk Enterprise Security can download STIX/TAXII feeds from any server that supports the TAXII 1.1 specification and the STIX 1.1.1 or 1.2 specification. Splunk Enterprise Security does not support downloading threat intelligence from text, VulnScanSPL, or Splunk Enterprise Threat Generator sources.

The correlation search feature that is used to throttle the creation of notable events is the window duration. The window duration is the time period during which a correlation search will not create a new notable event for the same issue. For example, if the window duration is set to 1 day, and a correlation search triggers a notable event for a certain condition, such as a brute force attack from a source IP address, the correlation search will not create another notable event for the same condition within the next 24 hours. This prevents the correlation search from generating too many alerts for the same issue, which can reduce the alert fatigue and noise. The window duration can be configured in the correlation search settings, under the Throttling section12. References = 1: Create a correlation search - Splunk Documentation - Throttling. 2: Throttle alerts - Splunk Documentation.

According to the Splunk Enterprise Security documentation, the Distributed Configuration Management tool is used to update indexers in ES. This tool allows you to create and distribute a Splunk Enterprise Security app for indexers, which contains the necessary configurations for indexers to work with ES, such as index-time field extractions, tags, and event types. The app name is Splunk_ES_ForIndexers.spl and it is created by running the distributed_config_manager.py script on the search head. You can then deploy the app to the indexers using the deployment server or the cluster master. Therefore, the correct answer is B. Distributed Configuration Management. References = Distributed Configuration Management.

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.

 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 main purpose of the Dashboard Requirements Matrix document is to identify on which data model(s) each dashboard in Splunk Enterprise Security depends. The Dashboard Requirements Matrix document is a web page that lists all the dashboards in Splunk Enterprise Security and the data model datasets that populate them. The data model datasets are linked to the Common Information Model (CIM) documentation, which describes the tags, field names, and field values that the events must use to be CIM-compliant. The Dashboard Requirements Matrix document helps you to determine which data models you need to enable and accelerate for your Splunk Enterprise Security deployment, and which data sources you need to map to the data models using the technology add-ons. References =

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.

According to the Splunk Enterprise Security documentation, the first step when preparing to install ES is to determine the size and scope of installation. This involves estimating the amount of data that you plan to ingest, the number of users that will access ES, the number of search heads and indexers that you need, and the hardware requirements for each component. This step helps you plan your deployment architecture and ensure optimal performance and scalability of ES. Therefore, the correct answer is D. Determine the size and scope of installation. References = Deployment planning.

Splunk Enterprise Security knows the local customer domain names so it can detect internal vs. external emails by using the Corporate Web and Email Domain Lookups. These are lookup files that contain the list of domains that are considered internal or corporate for the organization. The Corporate Web and Email Domain Lookups are edited during the initial configuration of Splunk Enterprise Security, and they are used to enrich events with the tag=internal_web or tag=internal_email fields. These fields indicate whether the web or email activity is internal or external, and they are used by dashboards and correlation searches in Splunk Enterprise Security to monitor and analyze the web and email traffic.

 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 =

 According to the Splunk Enterprise Security documentation, the Create Notable Event adaptive response action is one of the included adaptive response actions that is configured by default for ES. This action allows you to create a notable event from the results of a correlation search or from the details of another notable event. You can customize the title, description, urgency, owner, and other fields of the notable event. The Create Notable Event action is useful for creating alerts or tasks based on specific conditions or criteria. Therefore, the correct answer is A. Create notable event. References = Create Notable Event.

After installing the add-ons necessary for normalizing data, you should configure the add-ons according to their README or documentation. The add-ons that are included in the Splunk Enterprise Security package are preconfigured and do not require additional steps. However, the add-ons that are downloaded separately from Splunkbase may require additional configuration steps, such as enabling inputs, setting up credentials, or modifying props and transforms. You should review the README or documentation for each add-on to determine the specific configuration requirements and follow the instructions accordingly. References =

A correlation search is a scheduled search that runs periodically to detect patterns of interest in the data and generate notable events or other actions when the search conditions are met. A correlation search can generate false positives, which are notable events that do not represent a real security incident or threat. False positives can create noise and reduce the efficiency and accuracy of the security analysis. To reduce false positives from a correlation search, you can modify the correlation schedule and sensitivity for your site. The correlation schedule determines how often the correlation search runs and over what time range. The sensitivity determines the threshold or limit for the search conditions to trigger a notable event. By adjusting the correlation schedule and sensitivity, you can fine-tune the correlation search to match your environment and data sources, and avoid generating notable events for normal or benign activities. You can modify the correlation schedule and sensitivity for a correlation search using the Content Management page in Splunk Enterprise Security. 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 =
