What are risk objects in Splunk Enterprise Security?

Assets and identities such as systems and users in your organization are considered risk objects. Follow these guidelines to optimally configure assets and identities for RBA in Splunk Enterprise Security:

What are the alerts in Splunk?

In this Splunk tutorial we are going to learn about the Alerts in the Splunk. How to create an Alert, Types of Alert, the workflow of Alert, Comparison between different types of Alert, Real time Alert, Scheduled Alert, Rolling time Window trigging. Alerts occur when particular criteria are met for the search results.

What is the risk factor editor in Splunk Enterprise Security?

Asset and identity correlation. Use the Risk Factor Editor in Splunk Enterprise Security to increase or decrease the risk scores associated with your assets and identities. This helps to customize risk in your security environment based on evolving threat.

How RBA Reduces Alert Volumes

Security operations centers (SOC) are incredibly noisy places. They experience tens of thousands of alerts daily and are constrained by limited resources. As a result, only the highest priority alerts are examined, and most are later determined to be false positives or are simply abandoned. Hoping to improve things, teams pour resources into "perfecting" their correlation searches, but doing so paradoxically creates even more noise. The other option isn't much better: teams inadvertently create blind spots in their security coverage through alert suppression, making it even There has to be a better way. Splunk® Enterprise

(RBA) functionality to SOC operations. This helps organizations address the elephant in the room: alert fatigue. Analysts create risk attributions for entities (e.g., users or systems) when something suspicious happens. Then, instead of triggering an alert for each attribution, the attributions are sent to the risk index. Teams can enrich their risk attributions by appending relevant context, like annotating them against a relevant MITRE ATT&CK technique or applying a risk score. When an entity's risk score or behavioral pattern meets your predetermined threshold, then a notable event gets triggered, providing analysts with valuable context at the onset of their investigative process to of RBA extend well beyond these improvements as adopting a risk-based approach provides teams with a unique opportunity to pivot resources from traditionally reactive functions to proactive functions Reduce alert volume and enhance security operations

Let's create happier and more productive analysts by enabling them to conduct more security investigations.

Operationalize Cybersecurity Frameworks

Splunk Enterprise Security provides out-of-the-box alignments to leading cybersecurity frameworks like embedding the framework of your choice into your detections, your team can transform valuable security concepts into foundational cornerstones of your security operations. These frameworks form the base for proactive exercises like adversary simulation. Also, teams can use their preferred framework to quantify gaps (e.g., which MITRE tactics detections are covering) in their security coverage and determine the additional data sources needed to enhance security.

Complex Threat Detection

Historically, complex threat detection has posed a challenge for legacy SIEMs. The volume of disparate and-slow where it's hard to distinguish generated collection of attributions, it's easier to build detections for attackers to use low-and-slow tactics. For example, behavior spans three or more MITRE ATT&CK tactics coverage of your attack surface.

SOAR's automation capabilities reduce time

spent on security incident triage activities, and provide better context for the investigative process. SOCs including Indicators of Compromise (IOCs), from Splunk Enterprise Security to Splunk SOAR. Then, SOAR can automatically investigate all associated attributions simultaneously: IPs, domains, URLs, hashes, and more can be queued for automatic blocking. This ensures that risky devices or users present in your environment can be quarantined or disabled instantaneously, without the need for human interaction. This frees up time for your security team to focus on other high-value activities within the SOC.
