Case 1Segev, Porra, Roldan, 1998 Bank of America: Replacing the Corporate Network with the Internet for Critical Business Transactions -- What Happens to Security?
Bank of America (BofA) • at the time the second largest banking company (assets more than $227 billion) • in the United States and 36 other countries • supported all major electronic payment options • FedWire • ACH (capable of FEDI) • SWIFT(capable of FEDI) • CHIPS
FEDI transactions over the InternetThe Pilot Project • The purpose of the Pilot project was to test security, reliability and speed of exchanging FEDI transactions over the Internet under actual circumstances and with real transactions • In 1994, BofA teamed up with the Lawrence Livermore National Laboratories to start the twelve month long Pilot • At the BofA, the project organization included experts from the Global Payment Services, Interactive Banking unit, project management unit, telecommunications, information systems services unit, security and marketing. • At the LLNL side the corresponding areas were represented in the Pilot • Additionally SW/HW vendors and outside consultants were employed
The Technical System Designing and implementing the technical system consisted of: • reviewing the available sw and hw options for the Internet security system • integrating the chosen Privacy Enhanced Mail (PEM); Multi Purpose Internet Mail (MIME) and Sun workstation based solution with the existing BofA FEDI system (ECS) for encryption/decryption of the FEDI messages exchanged with LLNL over the Internet • LLNL’s already had a PEM/MIME server. At their side the project was a part of improving the accounts payable system

The FEDI -Management System • In addition to the technical security system, transactions were carefully monitored by the key participants in both organizations using • automatically generated email messages • telephones • faxes • beepers • paper reports • weekly meetings for solving recurring problems • Throughout the project the security of the network was additionally monitored using standard security procedures of both organizations. • The groups managing the firewalls of each organization conducted their own independent tests
Results of the first phase • During the seven months of the Pilot project all payments were received by the vendor banks within two days of the generation of the payment instructions • No messages were lost • No evidence of tampering with the transactions was discovered
Second Phase of the Pilot • After seven months, the maximum dollar amount for a single payment was increased from $10.000 to $100.000/vendor/day • LLNL expanded the use of the system to provide travel and entertainment reimbursements to its employees • volume testing with files consisting up to 1,000 transactions was conducted • the speed and reliability of the system remained high • delays were mostly caused by the FEDI systems not by the network
Summary of Problems • 49% of the problems encountered during the project stemmed from the systems being down or off line • Other problems included • transaction delivery problems (duplicate, delayed or lost transactions) (24%) • Application, operating system incompatibilities (17%) • message delivery problems (5%) • decryption problems (5%) • Error rate per month varied from 5% to 50%
The Future • The Pilot project served as a proof of concept • The production system is being designed based on the Pilot with heightened security, reliability and speed sensitivity • The project prompted a network security processes reevaluation at BofA • Organizational changes have taken place and are planned for • Open issues include Internet based information systems security management of which one central area is encryption key management
