Navigating the Complex Landscape of Ethical AI in Defense: Insights from Northrop Grumman Experts


Navigating the Complex Landscape of Ethical AI in Defense

Nevertheless, AI presents well-documented challenges related to data bias, vulnerability, and explainability. Northrop Grumman is collaborating with U.S. Government organizations to establish comprehensive guidelines for assessing the safety, security, and ethics of AI models intended for Department of Defense (DoD) use.


The Defense Innovation Board (DIB) of the DoD has responded proactively to AI challenges by introducing the AI Principles Project. Initially, this project outlined five ethical principles that AI development for the DoD should adhere to: responsibility, equity, traceability, reliability, and governability. To effectively implement these DIB principles, AI software development must also prioritize auditability and resilience against potential threats.


It is important to note that concerns surrounding AI ethics are not a recent development; they have existed since the inception of the concept of AI. These ethical principles represent a culmination of this historical perspective, aiming to harness the potential of automation while mitigating its associated risks. In this article, three AI experts from Northrop Grumman delve into the significance and complexity of applying the DIB's AI Principles in the realm of national defense.


Ethical AI: From Theory to Practice

According to Dr. Bruce Swett, Chief AI Architect at Northrop Grumman, the true challenge lies in operationalizing AI ethics – integrating ethical decision-making into AI systems to prevent subtle oversights or flaws that could lead to detrimental mission outcomes. Developing secure and ethical AI is inherently complex because it blurs the boundaries between traditional development and operational phases seen in conventional computing environments.


AI constantly evolves and undergoes updates, necessitating continuous retesting to ensure its safety, security, and ethicality. For instance, when an image-recognition AI is re-trained with a new dataset, it effectively reprograms itself, adjusting its internal recognition weights. Updating AI models with fresh data for enhanced performance can introduce new sources of bias, vulnerabilities, or instability, necessitating thorough testing for ethical and secure utilization.


Dr. Amanda Muller, a technical fellow and systems engineer at Northrop Grumman, emphasizes the multidisciplinary nature of addressing these challenges. She suggests that a comprehensive approach is required—one that encompasses technology, policy, and governance while considering multiple perspectives simultaneously.


Ethical AI and DevSecOps Integration

While some of these challenges are not unique to AI, the transition towards agile software development practices, characterized by frequent update cycles, has led to the integration of code generation stages, software development, and operations, resulting in the concept of DevOps. Recognizing that security cannot be an afterthought, the concept of DevSecOps emerged.


However, securing and ensuring the ethicality of AI goes beyond merely integrating development, security, and operations into one continuous process. When AI systems are deployed, they are exposed to not only learning experiences but also potential threats from hostile actors. Vern Boyle, Vice President of Advanced Processing Solutions at Northrop Grumman, highlights the importance of safeguarding AI against adversarial AI attacks—a vital consideration for DoD applications.


This risk is not confined to defense; even major tech companies have faced challenges when deploying AI, as demonstrated by a chatbot aimed at teenagers that was manipulated by trolls to respond with insults and slurs. In a defense context, the stakes are higher, potentially impacting a broader range of individuals. Attackers are expected to possess a deep understanding of AI and exploit its vulnerabilities. Protecting AI data and models throughout the AI lifecycle, from development through deployment and sustainment, is crucial for DoD applications of AI.


The Challenge of Contextual Understanding

Current AI capabilities excel at performing specific tasks with precision. However, they struggle to grasp context. AI operates within the confines of its designated application, lacking the broader contextual awareness that humans possess. For example, AI might struggle to determine whether a puddle of water is one foot or ten feet deep. Humans can contextualize information around the puddle to make a more informed judgment, realizing the potential danger of driving through it.


As Muller points out, human intelligence must remain an integral part of AI systems. This necessitates keeping humans involved in the process, even as systems become increasingly automated, and configuring interactions to allow humans to leverage their unique capabilities.


Toward a Future of Secure and Ethical AI

For Dr. Swett, the central ethical question for AI developers revolves around assessing whether an AI model aligns with DoD applications and how to instill justified confidence in its capabilities. An integrated approach to AI, encompassing AI policies, testing, and governance processes, will provide DoD customers with auditable evidence that AI models and capabilities can be utilized safely and ethically for mission-critical purposes.


In conclusion, as AI continues to advance and permeate various aspects of our lives, addressing the complexities of ethical AI in defense is of paramount importance. Northrop Grumman's experts emphasize the need for a multidisciplinary approach, integration with DevSecOps practices, and the essential role of human intelligence in navigating the intricate landscape of AI ethics and security. Ultimately, a comprehensive strategy is essential to ensure that AI serves as a valuable tool while safeguarding against potential risks and ethical concerns.
