You Should Know:

Splunk Fundamentals (Log Analysis & Dashboards)

  • Basic Search Command: 
    index="main" | head 10
  • Extract Fields: 
    | extract kvdelim="=", pairdelim=","
  • Create a Dashboard: 
    | timechart count by sourcetype

Microsoft Sentinel (Cloud SIEM)

  • KQL Query for Threat Detection: 
    SecurityEvent
| where EventID == 4625
| summarize count() by Account
  • Hunting Query for Suspicious Logins: 
    SigninLogs
| where ResultType == "50057"
| project UserPrincipalName, IPAddress, Location

Elastic Security (ELK Stack)

  • Search for Failed SSH Attempts: 
    GET /_search
{
"query": {
"match": { "event.type": "authentication_failure" }
}
}
  • Detect Brute Force Attacks: 
    GET /_search
{
"query": {
"range": { "event.count": { "gt": 5 } }
}
}

TryHackMe SOC Lab

  • Analyze Logs with grep: 
    grep "Failed password" /var/log/auth.log
  • Extract Suspicious IPs: 
    awk '/Failed password/{print $11}' /var/log/auth.log | sort | uniq -c | sort -nr

Blue Team Labs (BTLO) – Threat Hunting

  • Hunt for Persistence via Registry: 
    Get-ItemProperty -Path "HKLM:\Software\Microsoft\Windows\CurrentVersion\Run\"
  • Detect Lateral Movement with WMI: 
    Get-WinEvent -FilterHashtable @{LogName='Security'; ID=4688} | Where-Object {$_.Message -like "wmic"}

Security Onion Lab (Real-World SIEM Setup)

  • Start Zeek (Bro) for Network Analysis: 
    sudo zeekctl deploy
  • Check Suricata Alerts: 
    tail -f /var/log/suricata/fast.log

What Undercode Say

SIEM tools are essential for modern cybersecurity operations. Mastering Splunk, Sentinel, and ELK Stack enhances threat detection, while hands-on labs like TryHackMe and BTLO provide real-world experience. Always validate logs, automate threat hunting, and stay updated with emerging attack patterns.

Prediction

The demand for SIEM-skilled professionals will rise as cloud adoption increases. AI-driven SIEM solutions will dominate, requiring cybersecurity experts to adapt to automated threat detection and response.

Expected Output:

  • Splunk logs analyzed
  • Sentinel KQL queries executed
  • ELK Stack searches performed
  • TryHackMe SOC challenges completed
  • BTLO threat-hunting scenarios solved
  • Security Onion deployed successfully
