A process should be allowed to access only those resources for which it has authorization. Furthermore, at any time, a process should be able to access only those resources that it currently requires to complete its task. This is commonly referred to as the need-to-know principle, or domain of protection. Discuss this “domain” and its structure, including the following: Whether the relationship between a process and a domain is static or dynamic Domain switching How domain switching happens in the following cases: Each user is a domain Each process is a domain Each procedure is a domain

Question

A process should be allowed to access only those resources for which it has authorization. Furthermore, at any time, a process should be able to access only those resources that it currently requires to complete its task. This is commonly referred to as the need-to-know principle, or domain of protection.

  • Discuss this “domain” and its structure, including the following:
    • Whether the relationship between a process and a domain is static or dynamic
    • Domain switching
    • How domain switching happens in the following cases:
      • Each user is a domain
      • Each process is a domain
      • Each procedure is a domain
