SELKS (Suricata ELK Security): Advanced Usage Guide with Practical Exercises
SELKS (Suricata ELK Security): Advanced Usage Guide with Practical Exercises
Description:
Master SELKS with this advanced usage guide. Learn Suricata IDS/IPS, ELK Stack integration, real-time network monitoring, threat detection, and practical hands-on exercises for cybersecurity professionals.
What is SELKS?
SELKS (Suricata ELK Security) is a Debian-based Linux distribution designed for network security monitoring (NSM) and Security Operations Center (SOC) environments.
It integrates:
Suricata: High-performance IDS/IPS for threat detection
Elasticsearch: Log storage, indexing, and searching
Logstash: Log parsing and filtering
Kibana: Visualization dashboards and analytics
Filebeat: Log collection and forwarding
SELKS is used for real-time intrusion detection, network threat analysis, SOC monitoring, and incident response.
Key Use Cases
Network Intrusion Detection System (IDS)
Intrusion Prevention System (IPS)
Security Information and Event Management (SIEM)
SOC Monitoring and Incident Response
Malware traffic detection and analysis
Compliance and log auditing
Installing and Setting Up SELKS (Advanced)
1. Download and Install SELKS ISO
Official Website: https://www.stamus-networks.com
Installation options:
Live ISO
Dedicated sensor
All-in-One SOC lab
2. System Update
3. Network Interface Setup
Interface for management
Interface for monitoring in promiscuous mode
Practical Exercise:
Install SELKS in a virtual environment with two network interfaces (one for management, one for monitoring).

ELK Stack (Elasticsearch, Logstash, Kibana)
Elasticsearch
Stores all Suricata alerts and network logs
Logstash
Parses and filters network and IDS logs
Kibana Dashboards
URL:
http://localhost:5601Prebuilt Suricata dashboards: Alerts, Flows, DNS, HTTP, TLS
Create custom visualizations for threat analysis
Practical Exercise:
Visualize HTTP, DNS, and TLS traffic trends in Kibana.
Network Traffic Analysis (Advanced)

SOC and Incident Response with SELKS
SELKS enables SOC analysts to:
Build attack timelines
Track source and destination IPs
Map threats to MITRE ATT&CK
Identify indicators of compromise (IOCs)
Correlate alerts for faster incident response
Real-World Scenario Practice:
Brute force attack detection
Malware C2 communication
Port scanning and reconnaissance alerts
Advanced Threat Hunting in SELKS
Detect beaconing traffic
Analyze lateral movement in the network
Identify suspicious DNS tunneling
Inspect encrypted TLS traffic
