Explanation: The areas of information system, as separated by Information Assurance Framework, are as follows: Local Computing Environments: This area includes servers, client workstations, operating system, and applications. Enclave Boundaries: This area consists of collection of local computing devices, regardless of physical location, that are interconnected via local area networks (LANs) and governed by a single security policy. Networks and Infrastructures: This area provides the network connectivity between enclaves. It includes operational area networks (OANs), metropolitan area networks (MANs), and campus area networks (CANs). Supporting Infrastructures: This area provides security services for networks, client workstations, Web servers, operating systems, applications, files, and single-use infrastructure machines
