Which of the following services is often the first focus for policy preparation?

Focusing on Core Services as the first step in policy preparation is critical because these services are fundamental to the functionality and operation of the overall system. Core Services typically include essential infrastructure components that all other services depend on. By establishing policies for Core Services, you ensure that the most crucial elements of the infrastructure are securely managed and that they can effectively support the subsequent layers of application and business services.

In addition, securing Core Services often helps mitigate risks throughout the entire environment since they are usually responsible for vital operations such as authentication, data storage, and network routing. Once Core Services are properly configured with robust policies, it becomes easier to extend those policies to Application Services and Business Services that rely heavily on the integrity and availability of the Core Services.

Other service types, such as Business Services, Application Services, and Network Services, are viable areas for policy management but typically come after Core Services in the prioritization of policy development. This approach allows for a layered security strategy where foundational security measures are firmly established first.
