TL;DR
The paper presents GAF, a unified security layer for LLM applications that consolidates various defenses into a single, comprehensive enforcement point, enhancing protection for autonomous agents and tool interactions.
Contribution
GAF introduces a novel architectural layer that unifies multiple defense mechanisms for LLM applications into a single, cohesive system.
Findings
GAF provides comprehensive security coverage for LLM applications.
It unifies fragmented defenses into a single enforcement point.
GAF enhances protection for autonomous agents and tool interactions.
Abstract
This paper introduces the Generative Application Firewall (GAF), a new architectural layer for securing LLM applications. Existing defenses -- prompt filters, guardrails, and data-masking -- remain fragmented; GAF unifies them into a single enforcement point, much like a WAF coordinates defenses for web traffic, while also covering autonomous agents and their tool interactions.
