Companies have always needed to be diligent in keeping ahead of hackers — email and leaky employee devices are an old problem — but the situation has grown increasingly complex and urgent as countless third parties are granted remote access to corporate systems. This access comes through software controlling all kinds of services a company needs: heating, ventilation and air-conditioning; billing, expense and human-resources management systems; graphics and data analytics functions; health insurance providers; and even vending machines.

Break into one system, and you have a chance to break into them all as Hackers in the recent Target payment card breach did by gaining access to the retailer’s records through its heating and cooling system!!
