Practice Verified Codes and Commands
1. Splunk Search Query Example:
[splunk]
index=main sourcetype=access_combined status=200 | top limit=10 uri_path
[/splunk]
This query retrieves the top 10 most accessed URI paths with a status code of 200.
2. SOAR Automation Script (Python):
import requests
def block_ip(ip_address):
url = "https://api.your-soar-platform.com/block"
payload = {"ip": ip_address}
headers = {"Authorization": "Bearer YOUR_API_KEY"}
response = requests.post(url, json=payload, headers=headers)
return response.status_code
This script blocks an IP address using a SOAR platform’s API.
3. Linux Command for Log Analysis:
grep "Failed password" /var/log/auth.log | awk '{print $9}' | sort | uniq -c | sort -nr
This command identifies IP addresses with failed login attempts from the auth log.
4. Windows PowerShell for Security Logs:
Get-WinEvent -LogName Security | Where-Object {$_.ID -eq 4625} | Select-Object -First 10
This PowerShell command retrieves the first 10 failed login events from the Security log.
What Undercode Say
Cybersecurity is a dynamic field that requires continuous learning and hands-on practice. The Splunk courses listed above provide an excellent foundation for mastering SIEM tools, which are critical for Security Operations Centers (SOCs). By leveraging Splunk, analysts can efficiently detect, investigate, and respond to security incidents.
For those diving into Splunk, mastering search queries is essential. Commands like index, sourcetype, and `top` are powerful for log analysis. Additionally, integrating SOAR platforms can automate repetitive tasks, such as blocking malicious IPs, as demonstrated in the Python script.
On Linux systems, commands like grep, awk, and `sort` are invaluable for parsing logs. For example, analyzing `/var/log/auth.log` can reveal brute-force attempts. Similarly, Windows PowerShell commands like `Get-WinEvent` enable analysts to extract critical security events from the Event Viewer.
