Practice Verified Codes and Commands

1. Splunk Search Query Example:

index=main sourcetype=access_combined status=200 | top uri

This query retrieves the top URIs with a status code of 200 from the main index.

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 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 Command for Security Logs:

Get-WinEvent -LogName Security | Where-Object {$_.ID -eq 4625} | Select-Object -First 10

This command retrieves the first 10 failed login events from the Windows Security log.

What Undercode Say

Cybersecurity is a critical field that requires continuous learning and hands-on practice. The Splunk courses listed above provide an excellent opportunity to gain expertise in SIEM tools, which are essential for monitoring and defending against cyber threats. By mastering these tools, you can enhance your ability to detect, analyze, and respond to security incidents effectively.

To complement your learning, here are some additional commands and tools to explore:

  • Linux Commands:
  • netstat -tuln: Lists all open ports and listening services.
  • tcpdump -i eth0 -w capture.pcap: Captures network traffic on the eth0 interface.
  • chmod 600 file.txt: Restricts file permissions to read/write for the owner only.

  • Windows Commands:

  • netstat -an: Displays active connections and listening ports.
  • schtasks /query: Lists all scheduled tasks on the system.

  • icacls file.txt /grant User:R: Grants read-only access to a specific user.

  • Cybersecurity Tools:

  • Nmap: `nmap -sV -O target.com` for service and OS detection.
  • Wireshark: Analyze network traffic with advanced filtering.
  • Metasploit: Use `msfconsole` for penetration testing.
