Description: Policy evaluation is the process by which it is determined whether a specific policy applies to a given request in a computer system. This process is fundamental to ensuring security and compliance with regulations in various computing environments, including cloud computing and operating systems. Policy evaluation allows administrators to define and enforce rules that control access to resources, ensuring that only authorized users can perform specific actions. This evaluation is based on a set of conditions and criteria that are assessed in real-time, enabling dynamic and flexible management of permissions. This evaluation may include aspects such as the user’s identity, the context of the request, and the characteristics of the resource being accessed. Proper implementation of policy evaluation is essential to protect data and resources, as well as to comply with privacy and information security regulations.
