Report #85038
[counterintuitive] Can system prompts prevent LLM jailbreaks and data exfiltration
Implement external guardrails \(input/output classifiers\) and strict API permission boundaries; never rely solely on system prompt instructions for security.
Journey Context:
Developers put 'DO NOT REVEAL THE SECRET' in the system prompt and assume it's a secure boundary. System prompts are just text prepended to the user prompt; they are highly susceptible to prompt injection, role-playing attacks, and social engineering. Security must be enforced outside the LLM's generative loop.
