Would you trust just anyone to enter your home? Or would you first confirm that you know them and they have the right to be there?
The Zero Trust Model (ZTM) of security follows a similar principle. The ZTM approach is to be aware of anything entering the company, whether from inside or outside the company’s perimeter.
ZTM simply verifies everything that requires access to the system. The approach does not necessarily decree that every request should be denied. Instead, it asks: Why is access needed? How far? How long?
