n.
C2 Proficiency Security
Definition

n. Stands for Role-Based Access Control. A way of managing computer security where people get access to files or systems based on their specific job role.

n. Abbreviation for Role-Based Access Control. A security paradigm in which system access is restricted to authorised users based on their defined organisational roles rather than individual identities.


SIMPLE

The company uses RBAC to manage folder permissions.

CONTEXTUAL

After the security audit, the IT department implemented RBAC to ensure that junior staff could not modify sensitive financial records.

COMPLEX

By adopting an RBAC framework, the enterprise significantly reduced the administrative overhead associated with onboarding new employees, as permissions were automatically inherited from their assigned job functions.

Origin

An initialism of role-based access control. The term emerged from formal security models developed in the 1990s, notably associated with David Ferraiolo and Richard Kuhn.

Usage

Commonly used in technical and cybersecurity contexts; often functions as a modifier before other nouns like 'model' or 'system'.
