The federal agency that regulates banks today issued new rules for online security for financial institutions, instructing them to use minimal types of “layered security” and fraud monitoring to better protect against cybercrime. It’s the first time the Federal Financial Institutions Examination Council (FFIEC) has updated its rules since 2005, and the instructions to regulated financial services today focus on protecting high-dollar Automated Clearinghouse (ACH) transactions that have been targeted by sophisticated cybercrime groups that hijack business PCs in order to initiate fraudulent transactions.
