	# ✅ AWS Lambda Security Checklist

	A practical checklist to help developers write secure AWS Lambda functions—without needing to be security experts.

	---

	## 🔐 Input Validation
	- [ ] Validate and sanitize all incoming event data at the start of the handler.
	- [ ] Use strict schemas (e.g., Pydantic for Python) and whitelisting.
	- [ ] Avoid relying solely on frontend validation.
