The biggest data breach yet?

Heartland Payment Systems disclosed a data breach that could eclipse the current record set by TJX in January 2007. 

While not specifying the number of records that were compromised, Heartland’s systems were exposed for some period of time in 2008.  Heartland processes more than 100 million card transactions a month.

According to Computerworld, what may be more ominous is that cybercrooks are adding transaction processors to their typical target list of individual retail companies.

Another example of the pressing need for comprehensive data security measures,  including self-encrypting disk drives.
