🔒 Security Best Practices

✅ DO

✅ Use SSH keys instead of passwords
✅ Protect secrets with Ansible Vault
✅ Use become for privilege escalation
✅ Version control playbooks (not state)
✅ Restrict SSH access with security groups
✅ Audit changes and keep logs
✅ Use separate inventories per environment

❌ DON'T

❌ Store passwords in plain text
❌ Use root for everything
❌ Run playbooks without review
❌ Commit .vault_pass to Git
❌ Use same credentials everywhere
❌ Skip security group configuration
❌ Ignore error handling
