Splunk is a powerful SIEM (Security Information and Event Management) tool widely used in cybersecurity for log analysis, threat detection, and incident response. Below are 10 free Splunk courses to enhance your SOC (Security Operations Center) skills:
1. The Art of Investigation (Defense SOC Analyst)
2. Data and Tools for Defense Analysts
3. Developing SOAR Applications
4. Scheduling Reports & Alerts
5. Security Operations and Defense Analyst
6. to Cybersecurity Awareness
7. to Enterprise Security
8. Visualizations
9. The Cybersecurity Landscape
10. Understanding Threats and Attacks
You Should Know: Essential Splunk Commands & Cybersecurity Practices
1. Basic Splunk Search Queries
index=security_logs sourcetype=firewall action=blocked | stats count by src_ip
– Purpose: Lists blocked IPs from firewall logs.
2. Detecting Brute-Force Attacks
index=auth_logs sourcetype=linux_ssh "Failed password" | stats count by user, src_ip | sort -count
– Purpose: Identifies repeated failed SSH login attempts.
3. Creating Alerts for Suspicious Activity
index=web_logs status_code=500 | stats count by client_ip
– Action: Set an alert if `count > 10` in 5 minutes.
4. Linux Commands for Log Analysis
grep "Failed password" /var/log/auth.log | awk '{print $11}' | sort | uniq -c | sort -nr
– Purpose: Finds brute-force attack sources.
5. Windows Event Log Analysis with Splunk
source="WinEventLog:Security" EventCode=4625 | table _time, user, src_ip
– Purpose: Tracks failed Windows logins.
6. Automating Threat Hunting with SOAR
- Use Splunk Phantom (SOAR) to automate:
- Malware containment
- Phishing response
- Threat intelligence enrichment
7. Creating Splunk Dashboards
index=network_logs | timechart count by action
– Visualization: Bar/line charts for traffic trends.
