Splunk Enterprise Security Certified Admin Exam - SPLK-3001 Exam Dumps

Explanation:

In Splunk Enterprise Security (ES), the Risk Framework assigns a numeric risk score to objects (such as users, servers, or devices) to quantify their level of risk. Here’s how it works:

Risk scores are calculated based on correlation searches and threat intelligence.
Higher scores indicate higher risk (e.g., a user with multiple failed logins or a server communicating with a known malicious IP).
These scores help prioritize investigations (e.g., focusing on entities with the highest risk).

Why the Other Options Are Incorrect:

A. An urgency → Incorrect. While risk scores may imply urgency, the framework itself assigns scores, not urgency labels.
B. A risk profile → Incorrect. A "risk profile" is a broader concept (e.g., patterns of behavior), but the framework specifically adds numeric scores.
C. An aggregation → Incorrect. Aggregation refers to combining data, not risk scoring.

Key Concept:
Risk Adaptive Framework (RAF) dynamically adjusts risk scores based on:
. Threat severity (e.g., critical vs. low-risk threats).
. Recency (e.g., newer events weigh more heavily).
Analysts can view risk scores in the Risk Analysis dashboard and Incident Review.

Explanation:

In Splunk Enterprise Security (ES), the Short ID is a unique identifier used to track and reference a notable event easily—especially in cases where long event IDs or full search strings would be too cumbersome.

The option to create or view a Short ID is found in the Event Details section of a notable event. When you're viewing a notable event from Incident Review:

Click on a notable event.
In the Event Details pane that opens, you’ll see the Short ID (or an option to generate it).
This allows you to reference the event quickly in reports, investigations, or communications.

❌ Why other options are incorrect:

A. The Additional Fields: These contain other extracted fields from the event, not the Short ID.
C. The Contributing Events: This section shows the raw events that led to the notable, not metadata like the Short ID.
D. The Description: This is part of the correlation rule's output or user-provided details, not where Short ID is located.

Explanation:

If the Brute Force Access Behavior Detected correlation search is generating too many false positives, the most effective way to reduce sensitivity (assuming your input data is already correct) is to adjust the threshold conditions within the search logic.

Correlation searches often use conditional logic like:

| where failed_attempts > 5
or
| xswhere failed_logins from same src_ip > 10 in 5 minutes

By increasing these thresholds (e.g., changing > 5 to > 10), the search will trigger less frequently, i.e., only on more extreme cases, thus reducing false positives.

❌ Why the other options are incorrect:

A. Modify notable event status field: This changes how the event is displayed, not how often it's triggered.
C. Alter threshold to make it a more common match: This would actually increase the number of matches, making false positives worse.
D. Modify the urgency table: This affects urgency display, not search sensitivity. It changes how the event is prioritized, but not how often it’s generated.

Explanation:

In Splunk Enterprise Security (ES), the urgency of a notable event is determined by combining:

1. The event's security domain severity (e.g., high, medium, low).
2. The Priority field from the Asset or Identity list (e.g., "high" for critical servers or VIP users).

How It Works:

The Priority column in Asset/Identity lists defines how critical an asset/identity is (e.g., a CEO's workstation might be "high" priority).
Splunk ES cross-references this with the event severity to calculate the final urgency (visible in Incident Review).

Why the Other Options Are Incorrect:

A. VIP → A binary flag (yes/no), not used for urgency calculation.
C. Importance → Not a standard field in ES Asset/Identity lists.
D. Criticality → Often confused with "Priority," but not the field ES uses for urgency.

Key Concept:
Urgency = Event Severity + Asset/Identity Priority
Configure Priority in:
. Configure > Data Enrichment > Asset/Identity Management.

Explanation:

In Splunk Enterprise Security (ES), the recommended way for administrators to add a new lookup is by using the Content Management interface, which is purpose-built for managing correlation searches, lookups, dashboards, and other ES components.

To do this:

Go to Configure → Content Management
Click Create New Content
Choose Managed Lookup
Upload the file and define the lookup's settings (e.g., destination name, app context, permissions)

Using this method ensures the lookup is properly tracked by ES, making it easier to manage and integrate with correlation searches or other ES features.

❌ Why the other options are incorrect or not recommended:

A. Settings → Lookups → Lookup Definitions: This lets you define the lookup after the file is uploaded, not for uploading the file itself.
B. Settings → Lookups → Lookup table files: While this can be used to upload a lookup in core Splunk, it bypasses ES’s content management system, meaning the lookup won't be managed or tracked in ES.
C. Add to /etc/apps/SplunkEnterpriseSecuritySuite/lookups: This manual file placement is not recommended because it bypasses app controls and is not preserved during upgrades or deployments.

Explanation:

The Content Management page in Splunk Enterprise Security (ES) allows administrators to export (and import) various ES content types, including but not limited to:

Correlation Searches

Adaptive Response Actions
Data Models
Glass Tables (custom dashboards)
Workbench Panels
Notable Event Aggregation Policies
Managed Lookups

Why This Is Correct:

The Content Management interface (Configure > Content Management) provides a centralized way to export all supported ES content for backup, migration, or sharing.
You can select specific items or entire categories for export.

Why the Other Options Are Incorrect:

A/B/D → These options are too restrictive; the Content Management page supports exporting all listed content types, not just subsets.

Key Concept:

Use Cases for Content Management:

Migration: Move configurations between ES environments (e.g., dev → prod).
Backup: Preserve customizations before upgrades.
Sharing: Distribute threat detection rules (e.g., correlation searches) across teams.

Explanation:

When tuning a correlation search to reduce false positives, severity controls how alarming a notable event appears (e.g., "high" vs. "low" severity) but does not affect whether the event is generated in the first place.

Why This Is Correct:

Severity is a post-trigger attribute (it labels the event after the search fires).
Changing it does not alter the search logic or reduce the number of events generated.

Actions That Do Reduce False Positives:

B. Removing throttling fields → Allows the search to group events more broadly, reducing duplicates.
C. Increasing the throttling window → Aggregates events over a longer time, filtering transient noise.
D. Increasing threshold sensitivity → Requires stricter conditions to trigger (e.g., count > 10 instead of count > 5).

Key Concept:

To reduce false positives, modify the search logic (thresholds, throttling) or input data filtering.
Severity/urgency adjustments only impact prioritization, not event volume.

Explanation:

In Splunk Enterprise Security (ES), you can control which roles are allowed to transition a notable event from one status to another using the Status Configuration settings.

If an admin wants to prevent users with the ess_user role from changing the status of a notable event from Resolved → Closed, they need to:

Go to Configure → Incident Management → Status Configuration.
Select the "Resolved" status.
Under the status transitions, look at the transition from Resolved → Closed.
Remove the ess_user role from the allowed roles for that transition.

This ensures that users with the ess_user role cannot finalize the event by closing it, even if they can perform other transitions like setting events to "In Progress" or "Resolved".

❌ Why other options are incorrect:

B. From the closed status...: Status transitions are configured from the current status, not the target. You have to control what statuses can transition to Closed, not from Closed.
C. Give own_notable_events permission: This grants ownership control, not specific transition limitations.
D. Remove edit_notable_events: This would completely block the user from editing any notable event, not just limit transitions between specific statuses.

Explanation:

In Splunk Enterprise Security (ES), detailed identity information (such as user names, email addresses, roles, business units, location, etc.) is stored in a lookup file, typically a CSV file, used for identity enrichment.

This file is part of the Asset and Identity Framework and is imported through:

Configure → Data Enrichment → Identity Management

Once imported, the data is used to enrich events and notable events with contextual identity details, which enhances correlation searches, risk analysis, and investigations (e.g., through Identity Investigator).

❌ Why the other options are incorrect:

A. Identity Investigator index: Identity Investigator is a visual investigation tool, not a storage location.
B. Access Anomalies collection: This is related to notable events about unusual access patterns, not a source of identity info.
C. User Activity index: No such index exists by default. User activity is usually collected in indexed events, but identity metadata isn't stored there.

Explanation:

The Use Case Library in Splunk Enterprise Security (ES) contains a curated set of predefined security scenarios that help guide and accelerate ES implementation.

These scenarios include:

Descriptions of specific security threats or compliance requirements
Mappings to correlation searches, data models, and required data sources
Implementation guides and recommendations for tuning detection content

This feature helps administrators:

Understand what security outcomes ES can support
Prioritize deployment steps based on available data
Ensure proper data onboarding and correlation search activation

❌ Why the other options are incorrect:

B. Correlation Searches: These are the detection rules, but the Use Case Library ties them together into broader scenarios.
C. Predictive Analytics: This is not a standard core feature in ES and isn’t part of implementation guidance.
D. Adaptive Responses: These are actions taken after a notable event is triggered, not part of planning or implementation.
