QRadar AQL for suspicious process execution
SELECT FROM events
WHERE category=1003
AND "Image" LIKE '%cmd.exe%'
AND "ParentImage" LIKE '%browser%'
LAST 24 HOURS
Elastic Security detection rule
rule Suspicious_PowerShell_Execution {
condition:
process.name == "powershell.exe" and
(command_line contains "-EncodedCommand" or
command_line contains "IEX")
}
SIEM platforms require specialized query languages for threat hunting. These examples show pattern detection for brute force attacks, living-off-the-land techniques, and encoded PowerShell commands—exactly the skills developed in IBM’s analyst program.
5. TryHackMe: Network Reconnaissance Methodology
Nmap host discovery nmap -sn 192.168.1.0/24 Service version detection nmap -sV -sC -O 192.168.1.100 Vulnerability scanning nmap --script vuln 192.168.1.100 Web directory brute forcing gobuster dir -u http://192.168.1.100 -w /usr/share/wordlists/dirb/common.txt Subdomain enumeration subfinder -d target.com
TryHackMe’s penetration testing path teaches systematic network reconnaissance. This workflow progresses from host discovery to service enumeration, vulnerability assessment, and web application testing—building the methodology ethical hackers use in real engagements.
6. Google AI Essentials: Security Automation with Python
import openai
import json
from datetime import datetime
def analyze_log_suspicion(log_entry):
prompt = f"""
Analyze this security log for suspicious activity: {log_entry}
Return JSON with: threat_level, confidence, rationale, recommended_action
"""
response = openai.ChatCompletion.create(
model="gpt-4",
messages=[{"role": "user", "content": prompt}]
)
return json.loads(response.choices[bash].message.content)
Example usage
log = "User admin failed login 50 times from IP 192.168.1.15"
result = analyze_log_suspicion(log)
print(f"Threat Level: {result['threat_level']}")
The Google AI Essentials certification teaches prompt engineering for security automation. This Python script demonstrates how AI can augment security analysis by automatically assessing log entries and providing analyst recommendations.
7. Fortinet NSE Training: Firewall Policy Management
