What is defined as a body of evidence organized into an argument to assure claims about an information system?

• A. Security Assessment Report
• B. Artifact of Trustworthiness
• C. Assurance Case
• D. Determination Statement

Answer: (C)

The correct answer, Assurance Case, is a structured body of evidence presented in a way that supports claims about the security and trustworthiness of an information system. An Assurance Case provides a logical argument that integrates evidence, assumptions, and arguments to demonstrate that the system meets specific security requirements or standards. This method is particularly useful in complex environments where it is crucial to communicate the reasoning behind security measures effectively. In the context of information systems, the Assurance Case helps stakeholders understand the overall risk posture of the system by detailing how various security controls have been implemented and assessed. It outlines clear relationships between claims, evidence, and supporting rationale, which facilitates a better understanding of the security posture and the confidence level in the system's integrity. This systematic approach is particularly important for auditors and decision-makers when assessing compliance with security policies and regulations. The ability to convey confidence in a system through an Assurance Case ultimately supports informed decision-making and risk management efforts.
