TLDR: The research paper introduces the ‘AI Security Map,’ a holistic framework for organizing AI security knowledge, technologies, and their impacts. It divides AI security into two aspects: the Information System Aspect (ISA), covering internal system elements like confidentiality and integrity, and the External Influence Aspect (EIA), addressing impacts on individuals and society such as privacy and disinformation. The map clarifies direct and indirect chains of negative impacts, showing how technical compromises or AI misuse can affect various stakeholders. It provides insights into key vulnerabilities and offers recommendations for both fundamental and applied research in AI security.
As artificial intelligence (AI) becomes increasingly integrated into our daily lives and various industries, the importance of AI security has grown exponentially. While traditional information security focuses on confidentiality, integrity, and availability (CIA), AI introduces new complexities, extending the scope of security concerns to include elements like explainability, fairness, and privacy, and their far-reaching impacts on individuals and society.
Existing research has often focused on specific aspects of AI security, such as classifying attacks and defenses within particular domains or for individual AI elements. This fragmented approach makes it challenging to understand the broader relationships between different security elements and how negative impacts on AI systems can cascade to affect various stakeholders.
To address this challenge, researchers Hiroya Kato, Kentaro Kita, Kento Hasegawa, and Seira Hidano from KDDI Research, Inc. have developed a novel framework called the “AI Security Map.” This map provides a holistic organization of AI security knowledge, technologies, and their impacts on information systems and stakeholders. The core idea is to offer a comprehensive overview that helps in understanding the intricate interconnections within AI security.
The AI Security Map: Two Key Aspects
The AI Security Map is structured around two primary aspects:
1. Information System Aspect (ISA): This aspect classifies the essential elements that AI must fulfill within information systems. It primarily focuses on the traditional CIA triad (Confidentiality, Integrity, Availability) but also includes other crucial AI-specific elements such as Explainability, Output Fairness, Safety, Accuracy, Controllability, and Trustworthiness. Negative impacts identified under ISA are typically direct results of attacks on AI systems, affecting their functions and operations.
2. External Influence Aspect (EIA): This aspect encompasses elements that affect individuals and society as a result of AI being attacked or misused. It includes a wide range of concerns like Privacy, Misinformation, Usability, Consumer Fairness, Transparency, Reputation, Compliance with laws and regulations, Human-centric principles, Ethics, Economy, Physical impact, Psychological impact, Medical care, and Critical infrastructure. Importantly, negative impacts in the EIA can arise not only from attacks on AI within information systems but also from the misuse of properly functioning AI by malicious actors.
Interrelationships and Chains of Impact
A key contribution of the AI Security Map is its ability to illustrate the relationships between elements in the ISA and EIA. The map clarifies how a compromise or misuse of an element in the ISA can lead to negative impacts on individuals and society. The researchers identified two types of chains leading to these impacts:
- Direct Chain of Impacts: In many cases, the compromise of an ISA element directly affects individuals and society. For example, a breach of “Confidentiality” in an AI system can directly lead to a violation of “Privacy” for individuals. Similarly, issues with “Integrity” or “Availability” can have immediate social impacts, especially concerning critical infrastructure and medical care.
- Indirect Chain of Impacts: This involves a cascading effect where multiple impacts occur in a sequence. For instance, if the “Integrity” of a large language model (LLM) is compromised (e.g., via a prompt injection attack), it can affect the “Controllability” of the AI. This compromised controllability might then be exploited to generate “Disinformation.” If this disinformation spreads, it can influence human decision-making, violating “Human-centric principles” and ultimately causing psychological or financial harm to “Non-consumers” who encounter it. The map also highlights that AI misuse, even when ISA elements are technically sound, can trigger these indirect chains, leading to widespread societal harm.

Insights and Recommendations
By referring to the AI Security Map, the researchers gained several key insights. They observed that confidentiality is often a primary target for attacks in AI-based systems, and integrity is the most influential element in the ISA, as its compromise can affect almost all other elements. In the EIA, there are numerous negative impacts on individuals and society, and impacts from AI misuse tend to spread when the malicious objective is achieved rather than having an immediate effect.
The paper also provides recommendations for future research. For fundamental research, it encourages a holistic analysis of impacts when considering new attacks or countermeasures, suggesting the need for more granular definitions of security targets and quantitative assessment of impacts. For applied research, the map can be a valuable tool for business stakeholders, decision-makers, and AI system providers to understand potential risks and design more robust systems. For example, an LLM could use the map to identify relevant negative impacts from a news article about AI misuse, even inferring less obvious societal impacts like the compromise of human-centric principles.
In conclusion, the AI Security Map offers a crucial framework for navigating the complex landscape of AI security. By holistically organizing AI elements, attacks, defenses, and their far-reaching impacts on individuals and society, it provides a clearer understanding of how damage to AI-based information systems can affect people and society. This work serves as an important foundation for researchers and a wide range of stakeholders to better understand and address the multifaceted challenges of AI security.
