Secure SDLC practices directly require output neutralization for untrusted CSV content to block formula injection.

finds

Security testing in development can detect formula injection but does not itself implement the mitigation.

prevents

Secure SDLC mandates input validation and output encoding that directly prevents formula injection in CSV exports.

prevents

Application security requirements include rules for safe CSV generation and handling of untrusted data.

prevents

Secure architecture principles encourage safe data export design but do not specifically address CSV formula neutralization.

prevents

Secure coding standards explicitly require neutralization of special characters when writing CSV files.
