You Should Know: Essential Splunk Commands & Techniques
🔹 Basic Splunk Commands
Search logs for a specific term index=main "failed login" Filter logs by source type sourcetype=linux_secure Time-range filtering earliest=-24h latest=now Extract fields using regex | rex field=_raw "user=(?<user>\w+)" Statistical analysis | stats count by src_ip
🔹 Threat Hunting Queries
Detect brute-force attacks index=main "Failed password" | stats count by src_ip | sort -count Find unusual process executions index=main "process_started" | rare limit=10 process_name Identify suspicious HTTP requests index=main status_code=404 | top uri
🔹 Linux Log Analysis (Syslog & Auth Logs)
Monitor SSH login attempts (Linux)
grep "Failed password" /var/log/auth.log
Check sudo command executions
grep "sudo:" /var/log/auth.log
Analyze Apache logs for attacks
awk '{print $1}' /var/log/apache2/access.log | sort | uniq -c | sort -nr
🔹 Windows Event Log Analysis (PowerShell)
Extract failed login events
Get-WinEvent -FilterHashtable @{LogName='Security'; ID=4625}
Check PowerShell execution logs
Get-WinEvent -LogName "Microsoft-Windows-PowerShell/Operational"
