The operational task

Different encoded inputs can express similar hostile-looking payloads. Normalization can expose patterns hidden by some encodings.

What the implementation supports

Injection Shield normalizes inputs and applies implemented injection patterns. Review the actual normalization order and event fields in the integration.

Integration and limits

Parameterized queries, authorization, and application validation remain necessary. Normalization and signatures cannot establish that every encoding or injection attempt is detected.

Check collector wiring, the current event schema, and the enforcing component before relying on a response. Preserve the original event and verify the result on your actual deployment. An emitted alert does not prove that the initiating operation was stopped.
