Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

prevent

Directly requires validation of the keyword argument in loadDictItemByKeyword to reject SQL metacharacters before query execution.

detect

Enables monitoring of the Online Report API endpoint for anomalous SQL syntax or error patterns indicative of injection attempts.

prevent

Restricts the database privileges of the low-privilege account used by the API so that successful injection yields only limited impact.
