The fast evolution and enterprise adoption of AI has motivated dangerous actors to focus on these techniques with better frequency and class. Many safety leaders acknowledge the significance and urgency of AI safety, however don’t but have processes in place to successfully handle and mitigate rising AI dangers with complete protection of your complete adversarial AI risk panorama.
Sturdy Intelligence (now part of Cisco) and the UK AI Safety Institute partnered with the Nationwide Institute of Requirements and Know-how (NIST) to launch the newest replace to the Adversarial Machine Studying Taxonomy. This transatlantic partnership aimed to fill this want for a complete adversarial AI risk panorama, whereas creating alignment throughout areas in standardizing an method to understanding and mitigating adversarial AI.
Survey outcomes from the International Cybersecurity Outlook 2025 revealed by the World Financial Discussion board spotlight the hole between AI adoption and preparedness: “Whereas 66% of organizations count on AI to have probably the most vital affect on cybersecurity within the 12 months to come back, solely 37% report having processes in place to evaluate the safety of AI instruments earlier than deployment.”
So as to efficiently mitigate these assaults, it’s crucial that AI and cybersecurity communities are effectively knowledgeable about immediately’s AI safety challenges. To that finish, we’ve co-authored the 2025 replace to NIST’s taxonomy and terminology of adversarial machine studying.
Let’s take a look at what’s new on this newest replace to the publication, stroll via the taxonomies of assaults and mitigations at a excessive stage, after which briefly replicate on the aim of taxonomies themselves—what are they for, and why are they so helpful?
What’s new?
The earlier iteration of the NIST Adversarial Machine Studying Taxonomy targeted on predictive AI, fashions designed to make correct predictions primarily based on historic information patterns. Particular person adversarial strategies had been grouped into three main attacker targets: availability breakdown, integrity violations, and privateness compromise. It additionally included a preliminary AI attacker method panorama for generative AI, fashions that generate new content material primarily based on current information. Generative AI adopted all three adversarial method teams and added misuse violations as a further class.
Within the newest replace of the taxonomy, we develop on the generative AI adversarial strategies and violations part, whereas additionally guaranteeing the predictive AI part stays correct and related to immediately’s adversarial AI panorama. One of many main updates to the newest model is the addition of an index of strategies and violations firstly of the doc. Not solely does this make the taxonomy simpler to navigate, however it permits for a neater strategy to reference strategies and violations in exterior references to the taxonomy. This makes the taxonomy a extra sensible useful resource to AI safety practitioners.
Clarifying assaults on Predictive AI fashions
The three attacker targets constant throughout predictive and generative AI sections, are as follows:
- Availability breakdown assaults degrade the efficiency and availability of a mannequin for its customers.
- Integrity violations try to undermine mannequin integrity and generate incorrect outputs.
- Privateness compromises unintended leakage of restricted or proprietary data corresponding to details about the underlying mannequin and coaching information.
Classifying assaults on Generative AI fashions
The generative AI taxonomy inherits the identical three attacker targets as predictive AI—availability, integrity, and privateness—and encapsulates extra particular person strategies. There’s a fourth attacker goal distinctive to generative AI: misuse violations. The up to date model of the taxonomy expanded on generative AI adversarial strategies to account for probably the most up-to-date panorama of attacker strategies.
Misuse violations repurpose the capabilities of generative AI to additional an adversary’s malicious targets by creating dangerous content material that helps cyber-attack initiatives.
Harms related to misuse violations are supposed to provide outputs that would trigger hurt to others. For instance, attackers might use direct prompting assaults to bypass mannequin defenses and produce dangerous or undesirable output.
To realize one or a number of of those objectives, adversaries can leverage a lot of strategies. The enlargement of the generative AI part highlights attacker strategies distinctive to generative AI, corresponding to direct immediate injection, information extraction, and oblique immediate injection. As well as, there’s a completely new arsenal of provide chain assaults. Provide chain assaults should not a violation particular to a mannequin, and due to this fact should not included within the above taxonomy diagram.
Provide chain assaults are rooted within the complexity and inherited danger of the AI provide chain. Each element—open-source fashions and third-party information, for instance—can introduce safety points into your complete system.
These may be mitigated with provide chain assurance practices corresponding to vulnerability scanning and validation of datasets.
Direct immediate injection alters the conduct of a mannequin via direct enter from an adversary. This may be performed to create deliberately malicious content material or for delicate information extraction.
Mitigation measures embrace coaching for alignment and deploying a real-time immediate injection detection resolution for added safety.
Oblique immediate injection differs in that adversarial inputs are delivered through a third-party channel. This method can assist additional a number of targets: manipulation of data, information extraction, unauthorized disclosure, fraud, malware distribution, and extra.
Proposed mitigations assist reduce danger via reinforcement studying from human suggestions, enter filtering, and using an LLM moderator or interpretability-based resolution.
What are taxonomies for, in any case?
Co-author and Cisco Director of AI & Safety, Hyrum Anderson, put it finest when he mentioned that “taxonomies are most clearly essential to prepare our understanding of assault strategies, capabilities, and targets. Additionally they have an extended tail impact in enhancing communication and collaboration in a discipline that’s transferring in a short time.”
It’s why Cisco strives to help within the creation and steady enchancment of shared requirements, collaborating with main organizations like NIST and the UK AI Safety Institute.
These assets give us higher psychological fashions for classifying and discussing new strategies and capabilities. Consciousness and schooling of those vulnerabilities facilitate the event of extra resilient AI techniques and extra knowledgeable requirements and insurance policies.
