ABAC vs Zero Trust
ABAC (Attribute-Based Access Control) and Zero Trust (Zero Trust Architecture) both come up in technology conversations and get confused. Here's the plain-English difference, side by side, so you can use each one with confidence.
The key difference: ABAC refers to attribute-based access control, while Zero Trust refers to zero trust architecture — they describe different things even when they show up in the same sentence.
ABAC — Attribute-Based Access Control
Access model that grants permissions based on attributes of the user, resource, and context (location, time, device). ABAC scales where RBAC breaks — when "what you can do" depends on more than just your title.
Zero Trust — Zero Trust Architecture
Security model that assumes no user or device is trusted by default, even inside the network. Every request is authenticated, authorized, and encrypted — the perimeter is dead.
When to use ABAC
Reach for "ABAC" when the conversation is specifically about attribute-based access control. Access model that grants permissions based on attributes of the user, resource, and context (location, time, device). ABAC scales where RBAC breaks — when "what you can do" depends on more than just your title.
When to use Zero Trust
Reach for "Zero Trust" when the conversation is specifically about zero trust architecture. Security model that assumes no user or device is trusted by default, even inside the network. Every request is authenticated, authorized, and encrypted — the perimeter is dead.
