How to prevent Validated Cell From neither Copy and Past nor any other invalid criteria!

Dear Calibrators,
In need to find solution to prevent any way to change defined validations for some cells either using copy and past or other ways that can drop my lists.

Deeply thanks in advance.

While I search for solution in our respect FORUM, I got this one near to what I aim to and belong to 2010 VBA threads, so if any body can do as well its appreciated!
