LLM Security Framework

Threats Defenses Architecture Governance

A Framework for LLM Threat Modeling & Security

This interactive application synthesizes research on Large Language Model security. Explore the threat landscape, evaluate defense mechanisms, examine a secure deployment architecture, and assess governance maturity.

Threat Landscape Explorer

The security of an LLM is not defined by a single vulnerability, but by a complex interplay of risks across its lifecycle. Use the filters below to explore the unified threat taxonomy, which classifies threats by when they occur, where in the system they manifest, why an attacker pursues them, and what industry-standard category they fall into.

Lifecycle Stage (When)

All Stages

System Module (Where)

All Modules

Attacker Goal (Why)

All Goals

Adversarial Techniques in Practice

Theoretical risks become real-world exploits in high-stakes domains. This matrix illustrates how different adversarial techniques can manifest in sectors like healthcare, finance, and software development. Hover over a technique or domain to see concrete examples of potential harm.

Attack Technique Healthcare Finance Legal Services Code Generation

Defense & Mitigation Dashboard

There is no perfect defense. Securing LLMs involves navigating a fundamental trade-off between Security, Utility, and Cost/Performance. Use the controls below to select different defense configurations and observe how they impact these key metrics. This highlights the need for a balanced, portfolio-based approach to security.

Secure Architecture Blueprint

Effective LLM security relies on a defense-in-depth strategy, not a single tool. This blueprint outlines a modular, six-layer architecture designed to protect the entire LLM ecosystem. Click on each layer to explore its specific purpose and security controls.

Select a layer

Click on a layer in the diagram above to see its description and key security controls.

Governance & Maturity Model

Technical controls must be supported by a robust governance framework and a clear path for improvement. The maturity model below allows organizations to benchmark their current security posture across key domains and plan their journey toward a more proactive, optimized, and resilient state. Click each domain to see the progression from initial to optimizing.

This interactive application is an adaptation of the research paper “A Multi-Dimensional Framework for Threat Modeling, Security, and Governance of Large Language Model Ecosystems.”

Designed for educational and illustrative purposes.
