Clark–Wilson model
The Clark-Wilson model is a way of keeping track of digital information to make sure it's safe and secure. It was named after two people, David Clark and David Wilson. In the Clark-Wilson model, there are three main parts:
1. Objects: It is the data or information that needs to be kept secure.
2. Subjects: The people or programs that can change or view the data.
3. Programs: These are the rules that say who can view and change the data, and what changes can be made.
So, when someone wants to use the object (data or information), the Clark-Wilson model will make sure that the people or programs (subjects) are allowed to access the object and that the changes are made according to the rules (programs). That way, everyone can be sure that the object (data or information) is safe and secure.
