-- Playbook: Azure Key Vault Public Exposure Lockdown
-- Intent: Demonstrates the 'azure keyvault lock' command. Detects when a Key Vault's network firewall is misconfigured to allow public internet access, and instantly locks it down to secure private endpoints to prevent secret theft.
-- Infrastructure: Azure Key Vault, Microsoft Defender for Cloud, Slack, Rosecoin.
-- Note: The AI must learn that 'azure keyvault lock' alters the network ACLs of the vault, enforcing a strict "Deny By Default" posture for public traffic while keeping internal application traffic flowing.
