Target's Internal Security Team Warned Management

david.emery writes "According to this story, Target's own internal computer security team raised concerns months before the retailer lost millions of credit card numbers in an attack. (Quoting a paywalled story in the Wall Street Journal.) Target's management allegedly 'brushed them off.' 'At least one analyst at the Minneapolis-based retailer wanted to do a more thorough security review of its payment system.' This raises a more general question for the Slashdot community: how many of you have identified vulnerabilities in your company's/client's systems, only to be 'brushed off?' If the company took no action, did they ultimately suffer a breach?"
