Overview
Severity: MEDIUM | Affected: AI-SEC Foundation | Category: tool
The nonprofit AI-SEC Foundation has launched 'Guardian,' a new open-source security framework aimed at helping developers protect LLM-powered applications from common threats. Guardian acts as a real-time monitoring and intervention layer that inspects both user inputs (prompts) and model outputs. It uses a multi-layered defense strategy, including input validation, semantic analysis to detect jailbreak attempts, and canary-based detection to identify potential data leakage in model responses. The framework is designed to be highly modular, allowing developers to easily integrate it into existing applications and customize detection rules. The initial release includes pre-built modules for detecting prompt injection, SQL injection via LLM, and indirect prompt attacks. The AI-SEC Foundation hopes that Guardian will democratize AI security by providing a robust, free-to-use tool for organizations of all sizes.
