At a January Chamber of Commerce event on cyber security, I asked if anyone in the audience had been a victim of a data breach and several hands went up.  Then I asked who in the audience had shopped at Target in November or December and almost every hand went up.  Just about everyone has heard that Target Point-of-Sale systems were breached, and many of us were affected as consumers.  What many business owners don't know is that Target's initial network breach happened through a small HVAC vendor who had limited remote access to Target's network to remotely manage refrigeration and cooling.
