You Should Know: Essential KQL Commands & Practices

KQL is a powerful tool for log analysis, threat hunting, and security operations. Below are key commands and best practices:

1. Basic KQL Queries for Log Analysis

SecurityEvent 
| where EventID == 4625 // Failed logins 
| summarize FailedAttempts = count() by Account 
| sort by FailedAttempts desc 

2. Detecting Brute Force Attacks

SecurityEvent 
| where EventID == 4625 
| summarize Attempts = count() by bin(TimeGenerated, 1h), Account 
| where Attempts > 5 
| render timechart 

3. Hunting for Suspicious Processes

DeviceProcessEvents 
| where FileName in~ ("powershell.exe", "cmd.exe") 
| where InitiatingProcessFileName != "explorer.exe" 
| project Timestamp, DeviceName, AccountName, FileName, CommandLine 

4. Analyzing Network Anomalies

DeviceNetworkEvents 
| where RemoteIPType == "Public" 
| summarize ConnectionCount = count() by RemoteIP 
| where ConnectionCount > 100 
| join kind=inner (IPData) on RemoteIP 
| project RemoteIP, Country, ConnectionCount 

5. Advanced Threat Hunting with Joins

let MaliciousIPs = datatable(IP:string) [ "1.1.1.1", "2.2.2.2" ]; 
DeviceNetworkEvents 
| where RemoteIP in (MaliciousIPs) 
| join kind=inner (DeviceFileEvents) on DeviceId 
| project Timestamp, DeviceName, RemoteIP, FileName 

6. Automating Alerts with KQL

SecurityEvent 
| where EventID == 4688 // Process creation 
| where CommandLine contains " -nop -w hidden -e " 
| extend Alert = "Possible PowerShell Obfuscation" 
| project Alert, Timestamp, Computer, Account, CommandLine 

What Undercode Say

KQL is indispensable for modern cybersecurity, enabling real-time threat detection and forensic investigations. Mastering KQL enhances SIEM (Security Information and Event Management) capabilities, making it essential for SOC analysts and threat hunters.

Additional Linux & Windows Commands for Cyber Analysts

Linux:

 Monitor live authentication logs 
tail -f /var/log/auth.log | grep "Failed password"

Extract IPs from logs 
cat /var/log/secure | grep "Failed" | awk '{print $11}' | sort | uniq -c

Check open ports 
netstat -tulnp 

Windows (PowerShell):

 Get failed login events 
Get-WinEvent -FilterHashtable @{LogName='Security'; ID=4625}

Check suspicious processes 
Get-Process | Where-Object { $_.CPU -gt 90 }

Monitor network connections 
netstat -ano | findstr ESTABLISHED 

Prediction

As cyber threats evolve, KQL will become even more critical in automating threat detection. Expect deeper integrations with AI-driven anomaly detection in future Kusto releases.

Expected Output:

  • Enhanced KQL proficiency for threat hunting.
  • Practical scripts for immediate use in SOC environments.
  • Deeper understanding of log analysis for cyber resilience.
