A federal appellate court recently held that a bank is potentially liable to a customer for failing to catch fraudulent money transfers totaling over $500,000. (Patco Construction Company v. People's United Bank, 1st Cir., July 3, 2012, http://www.ca1.uscourts.gov/pdf.opinions/11-2031P-01A.pdf). The court held the bank's security measures were not "commercially reasonable," thereby exposing the bank to possible liability for the fraudulent transfers to be decided by the trial court.The decision is significant as it demonstrates the importance of people to security, and that effective data security is not just about the technology.

Bank personnel did not monitor the risk-scoring reports. The bank did not conduct any regular reviews of transactions that generated high risk scores. Bank employees should have been aware of the increased risk of compromise security because at the times in question keylogging malware was a persistent problem throughout the financial industry. Bank personnel should have understood that triggering the use of the same challenge...
