Payment authorization is the business process that approves a transfer, invoice, or change to payment details. It is the control point where finance decides whether money should move, which bank account should be used, and whether a request is legitimate.
In cyber security, this process is a frequent target because attackers do not always need to break into systems; they only need to trick a person into approving the wrong action. Business Email Compromise, vendor impersonation, and deepfake voice calls often aim at payment authorization by creating urgency, secrecy, or trust. A successful fraud can redirect funds, change supplier bank details, or authorize an invoice that should have been rejected.
Defenses focus on process hardening: use out-of-band verification for payment changes, require dual approval for high-risk transfers, and confirm requests through known contact methods rather than the message itself. Strong email controls help, but secure payment authorization is mainly about resisting social engineering and validating decisions before money moves.
