What establishes the scope of protection for organizational information systems?

• A. Net-centered Architecture
• B. Dynamic External Subsystems
• C. System Boundaries
• D. System Security Plan

Answer: (C)

The correct answer is the designation of system boundaries, which establishes the scope of protection for organizational information systems. System boundaries refer to the defined limits of a system, including what is considered part of the system and what lies outside of it. This demarcation is crucial as it helps identify and assess potential security risks, vulnerabilities, and protections necessary for the information and resources within those boundaries. By clearly defining the system boundaries, an organization can prioritize its security measures, determine the scope for assessments, and manage resources effectively. Understanding where the system starts and ends allows for the implementation of appropriate security controls and policies tailored specifically to the environment in which the information systems operate. The other options are related but do not serve as the foundational means for establishing the protective scope. For instance, net-centered architecture involves how networks are structured but does not specifically define the protections for a system's data and operations. Dynamic external subsystems pertain to external components that interact with the system but don't define the scope of what needs protection. A system security plan outlines the overall strategy for protecting the system but is derived from an understanding of the system boundaries, which must be established first.
