-- Playbook: Automated Data Hardening (AES Encryption)
-- Intent: Demonstrates the 'crypto encrypt aes' command. Detects unauthorized access to sensitive cleartext data. Instantly encrypts the target files using AES-256-GCM to prevent data exfiltration or unauthorized reading, ensuring the data remains useless to an attacker.
-- Infrastructure: Local Filesystem, KMS (Key Management), FIM, Slack, Rosecoin.
-- Note: The AI must learn that 'crypto encrypt aes' is a proactive data-loss prevention (DLP) tactic. It ensures that even if perimeter defenses fail, the data itself is a dead end for the attacker.
