Product Overview: Splunk Enterprise Security (Splunk ES)
Splunk Enterprise Security (Splunk ES) is a comprehensive security information and event management (SIEM) solution designed to enhance the security posture of organizations by providing advanced threat detection, incident response, and continuous security monitoring capabilities.
What Splunk ES Does
Splunk ES is built on the Splunk platform and leverages big data security analytics to improve the utilization and analysis of existing security-related data. It helps security professionals and decision-makers to analyze threats effectively, prioritize security events, and respond to incidents swiftly. The solution is versatile and can be deployed in various environments, including public and private clouds, on-premises infrastructure, and hybrid deployments.
Key Features and Functionality
Continuous Monitoring and Security Posture
Splunk ES enables continuous monitoring of an organization’s security posture through predefined dashboards and Custom Glass Table views. These views include security and performance metrics, trending indicators, and static and dynamic thresholds. The solution also offers a Use Case Library to facilitate quicker detection of new and known threats.
Incident Response and Investigation
Splunk ES optimizes incident response workflows with features such as centralized logs, pre-defined reports and correlations, alerts and incidents, and incident response workflows. It allows users to investigate and analyze breaches, tracing activities associated with compromised systems using ad hoc searches, the investigator journal, and the investigation timeline.
Rapid Investigations and Correlations
The platform facilitates rapid investigations by offering ad hoc search capabilities alongside static, dynamic, and visual correlations. This helps in detecting malicious activities quickly and developing threat context by pivoting on various data fields.
Endpoint Protection
Splunk ES provides robust endpoint protection features, including reports, searches, and a library of alerts for rare activities, malicious software (malware), and resource utilization and availability. It also integrates with other endpoint security solutions like Symantec Endpoint Protection, McAfee Endpoint Protection, and IBM Proventia Desktop.
Risk-Based Analysis
The solution allows users to assign risk scores to assets, events, users, and behavior, helping to prioritize security events and investigations. This risk-based analysis enables active management of business risk by tracking the security status of various components.
Data Collection and Integration
Splunk ES can collect and index data from virtually any source, including logs, relational databases, and data warehouses. It integrates with over 2,700 security and IT tools, making it easy to introduce various security tools and data sources into the platform.
Threat Intelligence and Behavior Analytics
Splunk ES integrates with the Splunk User Behavior Analytics (UBA) platform to detect anomalous behavior from both inside and outside sources. It also aggregates public security threat information from various sources through its Threat Intelligence Framework.
Advanced Analytics and Machine Learning
The solution leverages unsupervised machine learning to detect unknown threats and anomalous behaviors, accelerating security investigations by more than 50%. It enriches and prioritizes high-fidelity alerts with integrated threat intelligence, boosting SOC productivity and reducing fatigue.
Pre-Packaged Security Content
Splunk ES comes with over 1,400 out-of-the-box detections aligned to industry frameworks such as MITRE ATT&CK, NIST, CIS 20, and Kill Chain. This pre-packaged content helps in quickly identifying and responding to high-priority threats.
Unified Security Operations
The Splunk Mission Control application unifies detection, investigation, and response capabilities within one common work surface, simplifying security operations and enhancing the overall efficiency of the security team.
Conclusion
In summary, Splunk Enterprise Security is a powerful SIEM solution that provides comprehensive security monitoring, advanced threat detection, and streamlined incident response capabilities, making it an essential tool for organizations seeking to strengthen their security posture and mitigate risks effectively.
