The Challenge
Validating AI Security Controls Through Adversary Simulation
A global stock media brand was performing a security audit focused on AI risk. In the course of this audit, they discovered a serious problem: no one could tell them how to verify their controls. Vendors crowded around every side to reassure them they could provide the silver bullet tool, but no one could offer proof that those tools were working. Unless and until an AI-related incident occurred, it seemed, they were expected to take it all on faith. Being serious about their security, the client wasn’t willing to trust without verification.
The Solution
AI security validated, not assumed
We identified several major opportunities for no-cost improvements to the client’s security infrastructure, along with recommendations around strategic planning. We identified valuable unimplemented controls around API usage, found high-value logs not captured in alerts, helped senior leaders design and push a new DLP implementation, and worked with their engineers to validate an enterprise browser to upgrade and uniformly enforce security. The detailed, prioritized recommendations allowed the client to make strategic, defensible decisions around AI risk and to rapidly upgrade their resilience against it.
Best of all, we tied every single test and recommendation back to major AI frameworks (e.g., MITRE ATLAS, NIST SP 800-171, MAESTRO) to make it all fit smoothly into their audit.
