IriusRisk AI Threat Modeling & Machine Learning is a security library and toolset within the IriusRisk platform designed to enable threat modeling of AI and ML systems and applications. It follows the "secure by design" methodology, aligning with CISA guidance that AI systems must be secured from the ground up, rather than as an afterthought. The product centers around a dedicated AI/ML Security Library, which contains 28 specific components covering AI and ML concepts. This library allows users to construct threat models for AI and ML systems, identify associated risks, and receive insights into the security posture of those systems. The AI/ML Security Library is available in two tiers: - Community Edition: A free-forever version accessible to any registered user - Enterprise Edition: The full commercial threat modeling platform The library was developed by IriusRisk's internal security researchers and subject matter experts, and is described as the first of its kind for threat modeling AI and ML applications. It is positioned as a resource for teams seeking to integrate security considerations into AI/ML development from the design phase onward.
