Role-Based Access Control (RBAC)

Infrastructure
About 1 min read

A security management method that systematically controls access to AI models, data, and system functions by defining job-based 'roles' rather than granting individual permissions to users within an organization.

Detailed explanation

RBAC is a standard security model that ensures both security and operational efficiency by managing permissions based on organizational 'roles' rather than individual users. It is essential when adopting enterprise AI solutions to prevent sensitive data leaks in Retrieval-Augmented Generation (RAG) environments by restricting users from accessing the same information. Permissions can be granularly assigned—such as administrative tool access for admins, prompt engineering and model tuning for developers, and service usage for general users. This enables the 'Principle of Least Privilege', optimizes API costs by limiting indiscriminate and expensive LLM calls, and securely protects an enterprise's core prompt assets.

Why it matters when choosing tools

Enterprise AI tools are often connected to internal company documents, meaning that without RBAC, there is a risk of lower-level employees accessing sensitive RAG data such as HR information. Additionally, because usage costs vary by AI model, RBAC plays a critical role in reducing operational costs by restricting users to models with performance levels suited to their specific jobs.

What to check

  • Can custom roles tailored to company characteristics be created in addition to built-in roles (Admin, User, etc.)?
  • Does it support integrated management by linking with existing corporate directory systems (SSO, Active Directory, etc.)?
  • Can access permissions be configured differently for each RAG data source?
  • Can permission to use high-cost models be restricted to specific roles?

Real-world example

A user with a Legal Role can search internal contract databases through AI, whereas a user with a Marketing Role can be restricted to accessing only marketing guideline data even when using the same chatbot.
