Which type of authorization is not valid according to OMB, despite being used by some agencies?

• A. IATO
• B. IATT
• C. ATO
• D. TYPE

Answer: (A)

The reason that IATO, or Interim Authorization to Operate, is not considered valid according to OMB (Office of Management and Budget) guidelines lies in the emphasis placed on full Authorization to Operate (ATO) processes for federal information systems. While some agencies may still rely on IATOs for temporary authorization during the implementation or operational phase of a system, these interim approvals do not meet the full requirements set forth for establishing a comprehensive security posture. IATOs were initially designed to allow systems to commence operations while waiting for a full assessment and final authorization, but they do not provide the same level of assurance regarding risk management. The OMB strongly advocates for robust and formal risk assessment processes and comprehensive evaluations that lead to ATOs, thereby ensuring that all necessary security controls are assessed and that the systems pose an acceptable level of risk before they are put into operation. This stance supports the overarching goal of improving federal information security and ensuring that all systems are in compliance with established regulatory frameworks and best practices, ultimately leading to better protection of sensitive government data.
