Machine Learning (ML) and Artificial Intelligence (AI) systems, due to their critical and often complex nature, require stringent identity and access control mechanisms. An improper implementation in these systems can lead to overly permissive agency in model interactions. This might allow unauthorized individuals or entities to access, manipulate, or even control the model's operations, parameters, or outputs.
As ML/AI models are increasingly integrated into decision-making processes, their access control becomes a focal point of security. An improper control mechanism could permit unauthorized training data uploads, access to intermediate model layers, alteration of model parameters, or theft of proprietary model architecture.
-
Role-Based Access Control (RBAC): Implement RBAC to ensure that only authorized individuals can interact with the model based on predefined roles.
-
Multi-Factor Authentication (MFA): Enforce MFA for critical operations or administrative accesses to the ML/AI system.
-
Regular Review and Audit: Periodically review and audit user access rights, ensuring that no excessive permissions exist and obsolete permissions are revoked.
-
Logging and Monitoring: Maintain detailed logs of all access and operations on the ML/AI system. Use anomaly detection to identify and alert on unusual activities.
-
Encryption: Use encryption for data in transit and at rest, ensuring that even if unauthorized access occurs, the data remains protected.
- CWE-285: Improper Authorization - A failure to ensure that a user is given the right level of access.
- CWE-287: Improper Authentication - When the system doesn't verify the user's identity correctly.
- CWE-288: Authentication Bypass Using an Alternate Path - Bypassing authentication mechanisms through alternative methods.
-
Data Breach: Unauthorized access could expose sensitive training data or proprietary model details, leading to significant information leaks.
-
Model Sabotage: Malicious actors could alter model parameters or training data, causing the model to behave unpredictably or in a biased way.
-
Operational Disruption: Unauthorized actions could halt model operations, resulting in operational disruptions or downtimes.
-
Loss of Trust: Security incidents related to ML/AI models can severely damage the trustworthiness of the model's outputs and the organization's reputation.
-
Economic Impact: Data breaches or model misuses could result in significant financial losses, either through the misuse itself or through fines and penalties from regulatory bodies.
