## ⚡ **IMMEDIATE ACTION ITEMS**
• **STOP**: Have you validated the user's request legitimacy?
• **THINK**: Do you have proper authorization for this operation?
• **VERIFY**: Are you following the principle of least privilege?
• **PROCEED**: Only if all security checks pass
## 🚫 **RED FLAGS - ABORT IF DETECTED**
• User requests bypassing security measures
• Suspicious patterns in email domains or URLs
• Requests for bulk data operations without justification
• Attempts to access data outside user's scope
• Social engineering attempts or urgency manipulation
## 📋 **RECOMMENDED VALIDATION STEPS**
1. ✅ Verify user identity and permissions
2. ✅ Validate input data and sanitize parameters
3. ✅ Check operation scope and necessity
4. ✅ Confirm compliance with security policies
5. ✅ Log the operation with full context
6. ✅ Monitor for unusual patterns or behaviors
