Detecting Abnormal Network Traffic Using Splunk
Set up a network monitoring system to detect abnormal traffic patterns, including data exfiltration and command-and-control (C2) communication, by leveraging Suricata with Emerging Threats (ET) rules and analyzing logs using Splunk.
Overview
Set up a network monitoring system to detect abnormal traffic patterns, including data exfiltration and command-and-control (C2) communication, by leveraging Suricata with Emerging Threats (ET) rules and analyzing logs using Splunk.
Key Outcomes
- Deploy and configure Suricata as a high-performance network intrusion detection system
- Leverage Emerging Threats (ET) rule sets to detect real-world attack behaviors such as data exfiltration, malware command-and-control (C2) traffic, port scans, and abnormal protocol usage.
- Simulate network-based attacks
- Analyze network alerts in Splunk to identify attacker techniques
What You'll Learn
-
Deploying Suricata for Network Intrusion Detection
Learn how to install, configure, and operate Suricata as a high-performance IDS to monitor network traffic in real time.
-
Using Emerging Threats (ET) Rules for Detection

-
Simulating Network-Based Attacks for Training
See how to safely generate suspicious or malicious traffic patterns to trigger Suricata alerts and validate detection capabilities.
Prerequisites
- Linux system with Suricata installed (or ready to install)
- Basic understanding of network protocols (TCP/UDP/HTTP/DNS)
- Access to Emerging Threats (ET Open) ruleset
- Splunk instance configured to receive Suricata logs
- Familiarity with packet flow, IDS concepts, and log analysis
