Responding to the theft of 57 hard drives in 2009 , BlueCross BlueShield of Tennessee has completed a $6 million project to encrypt all of its at-rest data.
The project included a thorough inventory of stored data and was completed in just over a year.
The insurer said it is now encrypting all data on 1,000 Windows, AIX, SQL, VMware and Xen server hard drives; 6,000 workstation hard drives and removable media drives; 136,000 tape backup volumes; and 25,000 daily voice-call recordings.
The 57 hard drives, which were stolen from a leased facility in Chattanooga, Tenn., contained recordings of customer service telephone calls that included varying degrees of personal information on about a million of the insurer's subscribers. So far, there is no indication of any misuse of personal data from the stolen hard drives, according to the company.
"The lessons we learned from the theft led us to go above and beyond current industry standards, and our team has worked tirelessly to put new safeguards in place and encrypt all our at-rest data," said CIO Nick Coussoule in a statement.
