Threats and fraud can be perpetuated through cyberattacks, email compromise, account takeover, social engineering, and even vendor impersonation fraud. While these threats are not about a direct compromise of the ACH Network or other payment systems, they exploit vulnerabilities or gaps in processes or procedures. Nacha is committed to helping financial institutions, businesses, other organizations, and consumers protect themselves and prevent fraudulent activity.

WEB eResources

WEB transactions, or Internet-Initiated/Mobile Entries, are one of the fastest growing areas of Direct Payment via ACH. As more organizations look for sound business practices and solutions to offer WEB payment options, Nacha developed eResources to support businesses and financial institutions in implementing and using the WEB code.

These eResources will help organizations broaden payment options for customers of all types, realize efficiencies of electronic payments, and have necessary guidance to fully understand ways to address compliance, security and risk factors. They seek to expand knowledge and understanding among all stakeholders in the industry, supporting effective implementation of WEB transactions.

Encryption is a core technology that underpins the security of the ACH Network. The eResource, based on information gathered from industry professionals, underscores its value and generates greater awareness about the need for methods for all ACH Network participants to combat data threats and attack scenarios. ​

Authentication in the ACH Network is a common challenge among all ACH Network participants, particularly for WEB transactions. The eResource covers relevant risk management requirements for WEB in an effort to help participants better understand authentication technologies that are available on the market.

Authorization involves determining what information should be collected and retained so that there is adequate proof in the event that a transaction is challenged--a common challenge among ACH Network participants that originate or process WEB ACH consumer debit transactions. The ability to prove that a transaction was properly authorized is highly dependent on the attributes of the authorization process and any underlying processes used to validate identity, all of which may vary among institutions, transaction types and operating models.
