Risk mechanism

Training machine learning systems, particularly large language models, involves considerable investment. A significant risk is the potential theft of a system’s knowledge through direct observation of their input and output observations, akin to reverse engineering. This can lead to unauthorized access, copying or exfiltration of proprietary models, resulting in economic losses, eroded competitive advantage and exposure of sensitive information. This attack can be as simple as attackers making legitimate queries and analyzing the responses to recreate a model. Once replicated, the model can be inverted, enabling the attackers to extract feature information or infer details about the training data.

Applicability

Predictive ML Models · Fine-tuned LLMs · Pre-trained LLMs

Blank source cells remain null (unspecified); a source “No” means this default filter omits the risk; it does not establish absence in your architecture. Combine every deployment pattern in the system.

Source control guidance

• DASF 1: SSO with IdP and MFA to limit who can access your data and AI platform • DASF 2: Sync users and groups to inherit your organizational roles to access data • DASF 3: Restrict access using IP access lists that can authenticate to your data and AI platform • DASF 4: Restrict access using private link as strong controls that limit the source for inbound requests • DASF 5: Control access to data and other objects for permissions model across all data assets to protect data and sources • DASF 24: Control access to models and model assets • DASF 30: Encrypt models • DASF 31: Secure model serving endpoints to prevent access and compute theft • DASF 51: Share data and AI assets securely • DASF 32: Streamline the usage and management of various large language model (LLM) providers and rate-limit APIs • DASF 33: Manage credentials securely to prevent credentials of data sources used for model training from leaking through models • DASF 59: Use clean rooms to collaborate in a secure environment • DASF 55: Monitor audit logs • DASF 67: Federate authentication

Investigate and verify

Project adaptation: use the evidence workflow, then request investigate_risk with DASF-R-8.2. It returns the mechanism above, control-specific evidence requests, proposed tests and remediation acceptance criteria. Until evidence is supplied, the result is unverified. Use the finding template to record a concrete observation and residual risk.
