A. B. C. D.D.
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.
The Information Assurance Framework (IAF) is a structured methodology for ensuring the security and integrity of information systems. The IAF divides information systems into various areas, each with its unique characteristics and security requirements. The question is asking which area of the information system is a collection of local computing devices, interconnected via local area networks, and governed by a single security policy.
A. Local Computing Environments: This area refers to a single computer or a group of computers that are not interconnected. This area does not meet the criteria in the question.
B. Networks and Infrastructures: This area includes all of the interconnected network devices such as routers, switches, and firewalls. It also includes the cabling and other physical components that make up the network. While this area includes LANs, it also includes other types of networks such as wide area networks (WANs) and virtual private networks ( VPNs). This area does not meet the criteria in the question.
C. Supporting Infrastructures: This area includes all of the supporting components that enable the information system to function, such as power, cooling, and physical security. This area does not meet the criteria in the question.
D. Enclave Boundaries: This area refers to a collection of local computing devices, regardless of physical location, that are interconnected via local area networks (LANs) and governed by a single security policy. An enclave may be composed of one or more sub-networks that are connected by a common security perimeter, such as firewalls or other security devices. This area meets the criteria in the question and is the correct answer.
In summary, the correct answer is D. Enclave Boundaries, which refers to a collection of local computing devices, interconnected via local area networks, and governed by a single security policy.
