There is no OOTB rule to know whether it is password protected or not.
This would require a custom development effort to perform a method that would touch the suspect PDF, and determine if the PDF is password protected or not.
Example:
c# - checking if pdf is password protected using itextsharp - Stack Overflow
You can also do GOOGLE SEARCH TERMS:
