You Should Know:

1. SIEM & SOAR Fundamentals

SIEM (Security Information and Event Management) and SOAR (Security Orchestration, Automation, and Response) are critical in modern cybersecurity operations.

SIEM Commands (Splunk Example):

Search for failed login attempts 
index=security_logs sourcetype=linux_secure "Failed password" 
Detect brute-force attacks 
index=firewall_logs src_ip= | stats count by src_ip | sort -count

SOAR Automation (Python Example):

import requests 
def block_malicious_ip(ip): 
url = "https://api.firewall.com/block" 
payload = {"ip": ip, "reason": "Brute-force attempt"} 
headers = {"Authorization": "Bearer YOUR_API_KEY"} 
response = requests.post(url, json=payload, headers=headers) 
return response.json()

2. Threat Intelligence & Dark Web Monitoring

Tor Network Investigation:

Install Tor for anonymous research 
sudo apt install tor torbrowser-launcher 
Check Tor service status 
sudo systemctl status tor

Malware Analysis with YARA:

Scan a file for malware signatures 
yara -r malware_rules.yar suspicious_file.exe

3. Encryption & Compliance

OpenSSL Commands:

Generate a strong AES-256 encrypted file 
openssl enc -aes-256-cbc -salt -in secret.txt -out secret.enc 
Decrypt the file 
openssl enc -d -aes-256-cbc -in secret.enc -out decrypted.txt

GDPR Compliance Checks:

Audit file permissions in Linux 
find /var/www/html -type f -perm /o=w -exec ls -la {} \;

What Undercode Say:

Kim Crawley’s expertise highlights the need for human-driven cybersecurity analysis over AI-generated content. Practical SIEM queries, SOAR scripting, and encryption techniques remain essential for real-world threat mitigation. Organizations must invest in skilled professionals rather than relying solely on automation.
