8. Essential Tools • SIEM: Splunk, QRadar • EDR: CrowdStrike, Defender • Threat Intel: MISP, VirusTotal • Automation: Python, Sigma rules

9. Real-World Example Issue: Unusual login attempts on an executive account. Discovery: Threat hunters found stolen credentials in use. Action: Account locked, attackers blocked, security strengthened.
