You are tasked with setting up protection within a new project, and you are trying to decide on a formal security model to protect the resources (e.g., files). The two options are to implement an access matrix using the following:

Access lists that are associated with objects.
Capabilities that are associated with domains.

Compare the strengths and weaknesses of each type of implementation

Expert Solution

Step 1

Introduction

Access Matrix: An example of a security model for a computer system's protective state is Access Matrix. A matrix is used to depict it. The permissions of each process running in the realm with regard to each object are specified using an access matrix. The columns of a matrix represent objects, whereas the rows represent domains. Each entry (i, j) describes the collection of actions that a process operating in domains Di can call on object Oj, and each cell of the matrix represents a set of access permissions that are granted to the process of the domain.
