As more and more business information is transmitted between computer systems we are seeing an increased need to protect these Electronic Data Interchange (EDI) encoded transactions from unauthorized viewing and/or alteration. EDI transactions carry market intelligence such as item name, quantity, purchase price, delivery dates, etc. Unauthorized viewing can provide competitive information we may not want disclosed. With the advent of the Payment Order/Remittance Advice transactions, sensitive payment information such as payment amount, bank identification and bank account numbers can be carried in an EDI transaction. Alteration of any of these fields can result in an improper payment being made.
