Leveraging Splunk Cyber Security Capabilities for Advanced Security Operations
Splunk ES is the go-to option for cyber security experts. This powerful app provides an effective, robust means of defense against threats from email, web browsing, social media accounts, and other sources by monitoring incoming traffic for malicious activity or indicators of compromise (IOCs). With its integrated SOC capabilities and easily customizable settings to keep up with dynamic needs, Splunk ES offers complete visibility into your network environment so that potential risks or bad actors can be swiftly identified.
Splunk offers the following advantages for your SOC:
- Real-time insight into the status of your security,
- Single dashboard with centralized insights,
- Provides actionable insight for threat analysis and incident investigation, and
- Reduces false positives and other false alarms across your security infrastructure.
“With Splunk ES we are able to keep up with the ever-changing threat landscape and ensure our customers’ data is secure,” says CISO at Enterprise Financial company and valued customer of Hurricane Labs. “The combination of sophisticated analytics tools with built-in monitoring and visualization capabilities makes it an ideal choice for any security team looking for comprehensive protection.”
Additionally, security analysts are able to use collected data to build out SIEM use cases and intelligence profiles on detected threats for decisive action when necessary.

How does Splunk ES integrate with other systems for enhanced security?
Integrating is the process of bringing together and connecting the component subsystems into one system. Fortunately, Splunk is integration friendly. Splunk ES integrates with existing SIEM tools – such as network firewalls and multi-factor authentication tools (MFA) – and leverages machine learning algorithms to identify suspicious activity in your network traffic. Additionally, Splunk apps can be leveraged to further functionality across the platform and with no limitations.
You can use Splunk ES to monitor user behavior, detect anomalies, track threats across multiple systems, and respond quickly in the event of an attack. However, it’s good to note that custom integrations may be necessary to fully connect your systems and navigate complex environments. That’s where Hurricane Labs comes in.

What are correlation searches and advanced analytics that help security teams detect and defend against modern threats?
Data collection helps you capture all relevant events from across your IT infrastructure and store them in a centralized location for easy access. With event analysis and correlation rules you can detect suspicious activity by analyzing events from multiple sources in real time. Dashboards and reports provide visibility into your security posture in an easy-to-understand format that allows you to identify potential risks quickly.
A correlation search is a type of scheduled search that lets you detect suspicious patterns in your data. You can configure a correlation search to generate a notable event when search results meet specific conditions.
Splunk Docs provides a great overview of how you can plan the use case for the correlation search. As indicated in the tutorial, you “create a correlation search to address a security use case or problem that you want to solve. If you want to know when vulnerability scanners scan your network, or a high number of devices are infected with the same strain of malware, you can create a correlation search to detect that behavior and alert you. Correlation searches allow you to search across one or more types of data and identify patterns that could indicate suspicious or malicious activity in your environment.”
Along with correlation searches, Splunk ES enables security teams to defend against threats with advanced security analytics and intelligence that provide focused detection and specific alerts to shorten triage times.
What are the different data sources that can be indexed and analyzed by Splunk Enterprise Security?
Splunk can support any data type. Organizations are able to leverage different apps and add-ons that best suit business needs.
Hurricane Labs has identified eight data types that are important for SOC engineers and managers to be aware of for a comprehensive SIEM implementation. You can download The Big 8 PDF here.

Splunk ES Best Practices for Monitoring Modern Threats
When you’re leveraging Splunk ES as your SIEM solution, the main number one best practice is: whatever you’re going to do, make sure you do it with a plan.
This is where having specific SIEM use cases in mind come in handy. This is because you want to build alerts around those use cases. In addition, have an idea of how your data will be used as it’s only as good as the data you put into it.
