The defense approach against prompt injection is capability constraints rather than intent constraints: even if the model is tricked, it has no shell, network, or write privileges, and can only read files and generate diffs that require human review.

UnverifiedThe fundamental defense against prompt injection lies in narrowing permissions at the architectural level rather than relying on the model's comprehension, because models cannot reliably distinguish instruction boundaries; what truly prevents unauthorized operations is server-side rejection.79% similarUnverifiedSelf-generated prompt injection is a security risk in which the injected instruction originates from the model itself rather than an external attacker.79% similarUnverifiedThe focus of defending against indirect prompt injection cannot be on 'identifying malicious text' but must be on capability constraints—even if the agent is persuaded to call a tool, the system should have the authority to refuse that call.76% similarUnverifiedThe reliable defense against prompt injection is architectural least-privilege isolation: physically separating the steps that process untrusted content from the steps that have tool permissions, and adding a final human confirmation.75% similarUnverifiedThe hard constraints of formal methods encode safety rules as inviolable logical specifications, perform verification before action execution, operate independently of the model, and cannot be bypassed by attackers through manipulating model inputs.75% similar
