Multi-Agent Security: Building a Zero-Trust Inter-Agent Authentication Framework
blaizedsouza · x · 2026-08-12
As agents increasingly call other agents, open agent-to-agent calls pose significant security risks. The author proposes an Inter-Agent Authentication Framework, advocating for managing agents securely, much like microservices.
Core practices of the framework include:
- Issuing short-lived identity tokens to every agent
- Validating identity on every agent-to-agent call
- Scoping permissions based on agent roles
- Automatically rotating credentials
- Rejecting calls with missing/invalid identities and auditing all events
The author emphasizes never relying solely on network location for agent identity, enforcing a strict zero-trust policy.
