detects

Security testing in development and acceptance can detect calculation flaws before deployment.

prevents

Secure development lifecycle mandates verification steps that catch incorrect calculations before they reach production.

prevents

Application security requirements can explicitly call for numeric accuracy and bounds checking.

degrades

Secure architecture principles include input validation and safe arithmetic design that reduce calculation errors.

prevents

Secure coding standards directly prohibit unsafe arithmetic and require defensive checks against incorrect results.
