Common approaches to defending against prompt injection include: strictly separating the system prompt from user input, structurally validating model output, limiting the tools and data the model can access, and adding explicit rules to the prompt that treat overriding system instructions as an attack.

UnverifiedPrompt injection attacks can induce the model to output conclusions such as "this transaction is safe" by embedding malicious instructions in the field to be explained.79% similarVerifiedAn effective prompt injection defense system typically requires a combination of input content filtering, instruction source tracing, and pre-execution intent verification, as relying solely on the model's own safety training is insufficient to resist adversarial examples.78% similarUnverifiedPrompt injection defense should adopt a layered strategy: instruction source boundary labeling, capability gating, and output monitoring classifiers before executing tools with side effects.77% similarUnverifiedHardcoding validation logic on the server side rather than relying on system prompts to constrain model behavior is a fundamental engineering practice for defending against prompt injection attacks77% similarUnverifiedPrompt injection defense is usually divided into two layers: detection and filtering at the model layer (such as an anti-injection prompt section), and permission narrowing at the system layer (such as runtime isolation); the latter does not depend on model judgment and is therefore more reliable.75% similar
