You Should Know: Essential Splunk Commands & Cybersecurity Practices

Basic Splunk Commands for SOC Analysts

 Search for failed login attempts 
index=security sourcetype=linux_secure "Failed password"

Extract top source IPs generating alerts 
index=firewall | top src_ip

Monitor brute-force attacks 
index=security (fail OR denied) | stats count by src_ip

Track suspicious process execution 
index=endpoint process=cmd.exe OR powershell.exe | table _time host process

Linux Security Commands for Threat Hunting

 Check active network connections 
netstat -tulnp

Monitor login attempts 
grep "Failed password" /var/log/auth.log

List all cron jobs (check for malicious tasks) 
crontab -l

Analyze running processes 
ps aux | grep -i "suspicious_process"

Windows Security Commands for Incident Response

 Check active network connections 
netstat -ano

List scheduled tasks (malware persistence check) 
schtasks /query /fo LIST /v

Analyze event logs for security events 
Get-WinEvent -LogName Security | Where-Object {$_.ID -eq 4625}

Check for unusual services 
Get-Service | Where-Object {$_.Status -eq "Running"}

What Undercode Say

Splunk is a critical tool for SOC analysts, and mastering it can significantly enhance your cybersecurity career. These free courses provide hands-on knowledge, but practical implementation is key.

  • For Linux Security:
  • Use `auditd` to monitor file changes (auditctl -w /etc/passwd -p wa).
  • Detect rootkits with rkhunter --check.
  • Analyze logs in real-time with journalctl -f.

  • For Windows Security:

  • Use `Sysmon` for advanced logging (Get-WinEvent -Path C:\Logs\sysmon.evtx).
  • Detect lateral movement with logparser.exe.

  • Check for Mimikatz traces in logs (EventID 10).

  • For Splunk Automation:

  • Automate alerts with | savedsearch "Suspicious_Activity".
  • Use `lookup` commands to enrich threat intelligence.

Expected Output:

By combining Splunk expertise with OS-level security commands, you can build a robust defense against cyber threats. Enroll in these courses, practice the commands, and stay ahead in cybersecurity! 🚀
