Which of the following is NOT a key document used for risk-based authorization decisions?

• A. SSP
• B. POAM
• C. IATO
• D. SAR

Answer: (C)

The correct answer indicates that "IATO" (Interim Authority to Operate) is not considered a key document for risk-based authorization decisions. Risk-based authorization is primarily focused on assessing and managing risks associated with information systems, which is facilitated by certain key documents. The System Security Plan (SSP) is crucial as it outlines the security controls in place and provides a comprehensive overview of how security is managed within the system. It serves as a basis for understanding the risk profile of the system. The Plan of Action and Milestones (POAM) is also essential in a risk-based approach. It identifies any deficiencies in the system's security controls and outlines the steps needed to address these gaps. This document helps in tracking corrective actions and remaining risks. The Security Assessment Report (SAR) provides the results of security testing and evaluation, detailing the effectiveness of the implemented security controls. It is vital for decision-makers to understand the potential risks associated with the system after assessment. In contrast, while the IATO does provide an interim level of authorization usually pending further evaluation, it does not play a direct role in formally assessing risks or deciding ongoing security status based on risk. Rather, it is more of a temporary measure that indicates a system is permitted to operate under
