SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires presidio-analyzer, presidio-anonymizer, nemoguardrails, PyJWT, structlog, and includes scripts (resource) and references (resource) components.

What problem does it solve?

This Skill protects AI and LLM deployments from critical security vulnerabilities like prompt injection, data exfiltration, and model theft, ensuring the integrity and safety of your AI systems.

Core Features & Use Cases

  • Prompt Injection Defense: Implements input sanitization and guardrails to prevent malicious prompt manipulation.
  • Data Exfiltration Prevention: Includes output filtering and PII scrubbing to protect sensitive information.
  • API Security: Provides examples for rate limiting, token verification, and input validation for LLM API endpoints.
  • Model Weight Security: Details methods for verifying model integrity and scanning for malware.
  • Use Case: Secure a customer-facing chatbot by preventing users from tricking the LLM into revealing sensitive system information or executing unintended commands.

Quick Start

Use the ai-security-hardening skill to sanitize user input before sending it to the LLM.

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I protect my LLM application from prompt injection attacks?

To protect against prompt injection, this Skill implements input sanitization and guardrails using NeMo Guardrails to prevent malicious prompt manipulation before user input reaches the LLM.

Can I use Presidio to scrub PII and prevent data exfiltration in LLM outputs?

Yes, you can use Presidio to prevent data exfiltration by applying output filtering and PII scrubbing to LLM responses, ensuring sensitive information is removed from generated text.

How do I secure LLM API endpoints against unauthorized access?

You can secure LLM API endpoints by implementing rate limiting, JWT token verification, and input validation using PyJWT to control access and prevent API abuse.

What is the best way to verify model integrity and prevent model theft?

The best way to verify model integrity is by scanning model weights for malware and implementing strict access controls to prevent unauthorized model theft in production AI systems.

Does this approach work for securing customer-facing chatbots?

Yes, this approach works for customer-facing chatbots by sanitizing user inputs and filtering outputs, preventing users from tricking the LLM into revealing sensitive system information or executing unintended commands.

Why do I need input validation and output filtering for production AI systems?

Input validation and output filtering are required for production AI systems to enforce compliance controls, block malicious prompts, and ensure sensitive data is not leaked during LLM interactions.
