Hey Community!
When it comes to building AI applications, the race to market often leaves security trying to catch up. But what if adhering to the right guardrails actually gave your development process a competitive boost?
Our Mandiant offensive security teams are on the front lines stress-testing AI systems to understand their unique vulnerabilities. Recently, they conducted adversarial assessments on a pre-production banking chatbot. By uncovering an exposed API endpoint, our red team intercepted chat history data sent in easily modifiable JSON and injected fake "system" messages. The large language model, accepted this falsified history as fact, bypassed its primary instructions, and allowed the red team to make unauthorized account changes.
The takeaway? Securing mere model prompts isn't enough. You have to secure the entire AI application.
Based on these hands-on assessments, we've distilled our recent findings into five critical lessons to help you securely develop and deploy AI applications:
- Defend your AI pipeline from end to end: Security shouldn't be a final layer. Integrate it across all phases of the SDLC, from data ingestion to deployment.
- Don't take front-end data at face value: Threat actors will try to intercept and modify client-side data structures. Move from trusting user input to continuously verifying it with cryptographic signatures like HMAC.
- Lock the door on system-level prompts: Block privilege escalation at the application layer by configuring your logic to sanitize data and drop privileged system messages originating from the UI.
- Stick to application security basics: AI relies heavily on third-party libraries and orchestrators. Apply standard application security testing and vulnerability scanning to your entire AI tech stack.
- Build an early warning system: Integrate application and infrastructure logs with centralized security monitoring tools for real-time detection and response.
Building AI securely is a foundational requirement for realizing the full potential of this technology.
