Beth Jacob, the chief information officer at Target Corporation, has resigned. Her resignation comes at a time where Target fell victim to a recent credit card data breach. Target CEO, chairman, and president Gregg Steinhafel said that the company is overhauling their information security and compliance structure. The breach involved theft of around 40 million credit and debt card records and 70 million records containing the personal information of customers. Jacob was named CIO in 2008 and will be replaced with an external hire.
