R02 — Business Email Compromise (BEC)

Q: How do security teams mitigate Business Email Compromise (BEC)?

In CISO Game, Business Email Compromise (BEC) is reduced by Awareness (45%), Prevention (30%), Detection (25%) subscores. Real-world programs use the same control families, with category investments such as Basic email gateway, Advanced email security (anti-BEC), Phishing simulation platform.

Q: Why does Business Email Compromise (BEC) matter to a CISO?

Severity 8 (Major). Business Email Compromise is the highest-dollar attack vector by reported losses (the FBI's IC3 has put the cumulative impact above $50B). It rarely shows up in posture-tooling demos because there's no malware to detect — just a well-researched social-engineering path through finance approval workflows. The CISO Game lever is the awareness + identity stack (DMARC, MFA on every shared mailbox, out-of-band confirmation policies for wire changes), not the next EDR upgrade.
