In the digital age, organizations must navigate the junction of strong risk management with artificial intelligence (AI). It is critical to comprehend and reduce the dangers associated with AI applications as they become increasingly integrated into company operations. Companies must recognize, evaluate, and effectively manage AI risks, including everything from establishing tolerance to implementing controls.
This is where NIST’s AI Risk Management Framework (RMF) comes into play.
The NIST AI Framework provides organizations and security individuals with tools to improve the reliability of AI systems and promote their responsible design, development, implementation, and usage in the long run. To ensure responsible AI development and usage, the AI RMF aims to provide organizations utilizing and deploying AI systems with resources to manage and reduce risks associated with using AI systems.
In this blog, we will briefly overview NIST’s AI Risk Management Framework — what it is, how it defines a trusted AI system, the actionable guidance it offers for AI systems, and the steps required for implementing it for your AI product organization.
What is the NIST AI Risk Management Framework?
The NIST AI Risk Management Framework is a set of industry-neutral guidelines released by the National Institute of Standards and Technology (NIST) in January 2023 to assist organizations in evaluating and managing the risks related to deploying and using AI systems in today’s ever-changing digital environment.
Artificial intelligence (AI) is transforming several industries and opening up previously untapped prospects as it advances quickly. However, new risks and difficulties arise as AI develops and becomes more widely used. For instance, the application of AI systems may threaten the rights of persons and civil freedoms. NIST created the artificial intelligence risk management framework in response to these worries and new hazards. The NIST AI Framework aims to optimize the benefits of using AI technologies and address their drawbacks.
The guidelines of the NIST AI RMF offer a systematic way to recognize, evaluate, and lessen the hazards related to AI systems. This paradigm helps organizations traverse the complex world of artificial intelligence (AI) while guaranteeing the ethical use of AI and promoting accountability and transparency amongst the developers and users of AI systems.
Let’s see how the NIST AI Risk Management Framework defines a trusted AI system.
What is a Trusted AI System Based on the NIST AI Risk Management Framework?
To understand if your organization successfully governs AI system development and deployment, you must first know how the NIST AI Risk Management Framework defines a “trusted AI system.”
The NIST AI RMF defines several variables to assist organizations in determining how reliable an AI system is. These include:
Validity and Dependability The AI system should function as planned and consistently generate accurate findings, which is crucial in determining the validity of the AI’s outputs for use in decision-making processes.
Security and Resiliency To guard against malicious attacks, misuse, and unauthorized access, trusted AI systems should be built with strong security features. In addition, they must be able to bounce back fast and continue operating during and after any disruptive incidents.
Improved Privacy: A reliable AI system protects user privacy by putting safeguards in place to safeguard sensitive data and ensuring its use conforms with applicable rules and laws.
Transparency and Accountability: Accountability pertains to the auditability of a system, i.e., it should be evident who bears responsibility for the acts of the system. Transparency entails an unobstructed view of the system’s workings; an AI system’s decisions should be visible to humans and not concealed behind a “black box.”
Interpretability and Explicability: The AI system must offer concise and intelligible justifications for any decisions or actions to maintain user confidence and system accountability.
Fairness, with Zero Negative Biases: Unfair biases or discrimination should not be incorporated into the design of the AI system. This entails a concerted effort to locate and eliminate any detrimental biases in the system’s architecture or results.
So, what do the NIST AI RMF guidelines say? In this next section, we will delve into the actionable guidance provided by the NIST AI Risk Management Framework. This guidance is categorized into four phases, each of which will be detailed below.
Actionable Guidance Provided by the NIST AI Risk Management Framework
There are two sections to the NIST AI Risk Management Framework.
In the first, the features of trustworthy AI systems are defined, and organizational risks associated with AI are framed. The second section provides additional practical advice on successfully putting the framework into practice, enabling your company to continuously map and reduce risk throughout an AI system’s life cycle.
As mentioned above, the guidance is segregated into four phases, which are as follows:
Govern
The governing function, present across multiple tiers and permeating every process step, is an essential component of AI risk management.
The first layer comprises policies establishing an organization’s mission, culture, values, objectives, and risk tolerance. Technical teams go to work operationalizing and putting those policies into practice, producing thorough documentation to improve accountability. Senior leaders assist in creating a consistent and responsible risk management culture and tone in the meantime.
Rather than existing as a stand-alone component, governance should be incorporated into every other NIST AI Risk Management Framework function, particularly those associated with assessment and compliance. This can foster a strong organizational risk culture through strong risk governance, which can improve internal processes and standards.
Mapping
This function helps define and put the risk connected to an AI system in perspective. Information silos between teams are commonplace due to the inherent complexity of most AI systems.
Teams in charge of one aspect of the process might be unable need to help supervise or regulate others. Mapping aims to reduce potential risks and fill in these gaps by extracting information from all the stakeholders involved.
This further translates into informed decision-making, leading to possible sources of negative risk being proactively identified, evaluated, and addressed. The mapping process results also provide a crucial basis for the latter two phases, measurement and management.
Measure
The measure function uses tools, techniques, and methodologies — quantitative, qualitative, or a mixture of both — to assess, analyze, benchmark, and monitor AI risk and its related impacts. It also involves documenting system functionality, social impact, and trustworthiness.
This function helps organizations adopt or develop processes that include rigorous software testing and performance assessment methodologies, complete with measures of uncertainty, benchmarks for performance comparison, and formalized reporting and documentation of results.
Manage
The role of the manage function is to allocate resources regularly to address the risks identified and measured in the preceding processes.
The mitigation measures should include information about the organization’s response to, recovery from, and communication of an incident. Using the data acquired from the earlier phases, the manage function seeks to lower the probability of problems or system breakdowns.
It is finally time! In this next section, we will provide a five-step guide on implementing NIST’s Risk Management Framework in your organization.
How do you implement the NIST AI Risk Management Framework in an organization?
There are five steps as follows to applying the NIST AI RMF in any organization:
Determine the Goals and Purpose of the AI System
Establishing a clear understanding of the system’s objectives is the first step in developing a trusted AI system using the NIST AI RMF. During this step, an organization can pinpoint the risks connected to the planned application of the AI system. For instance, an AI system used for credit scoring will carry a different level of risk than one used in driverless cars.
Identify the AI System’s Data Sources and Assess Them for Biases
In the second stage, every data source that the AI system uses is identified, and a thorough bias analysis is carried out. Effective execution of this procedure is guided by the NIST AI RMF guidelines, which focus on comprehending the context of the data, spotting potential bias, and mitigating it to develop an ethically secure AI system.
Implement the NIST AI RMF Guidelines During Development
This third step requires implementing the AI RMF’s actionable guidelines while the AI system is still being developed. This entails introducing the four functions of the AI RMF — govern, map, measure, and manage — into the process of developing the system. By taking this step, risks are handled proactively as opposed to reactively.
Monitor and Test the Developed AI Systems Regularly
Regular testing and monitoring are crucial to guarantee that the system continues to satisfy the established performance parameters and operates as intended. As a critical component of risk management for AI systems, the AI RMF advocates for ongoing monitoring.
Actively Improve AI Systems Based on Findings
This final stage involves using the knowledge gathered from testing and observation to actively work toward continuously enhancing the AI system. This demonstrates how the AI RMF’s emphasis on iterative development is essential to successfully managing AI risks. By taking this step, you can be sure that the system will keep evolving and adapting to new data and environmental circumstances.
