Mitigating Controls (NIST 800-53 r5) AI

prevent

Directly requires validation and neutralization of special elements in query inputs to block the malformed data logic that triggers the DoS condition.

prevent

Restricts authenticated users to the minimum privileges needed for queries, limiting the ability to reach or exploit the vulnerable configurations.

prevent

Implements mechanisms to protect against or limit the effects of denial-of-service attacks originating from database query processing.

prevents

Secure SDLC practices directly require proper quantity/length validation in input handling.

detects

Security testing in development can detect missing quantity validation but does not itself implement the control.

prevents

Secure development lifecycle mandates input validation for quantity fields, directly preventing CWE-1284.

prevents

Application security requirements explicitly call for validation of size/length inputs, mitigating CWE-1284.

prevents

Secure architecture principles encourage robust input handling but do not specifically address quantity validation.

prevents

Secure coding standards require explicit checks on numeric quantity inputs, fully addressing CWE-1284.
