Target attack shows danger of remotely accessible HVAC systems

Jaikumar Vijayan | Feb. 10, 2014
The massive Target breach led to revelations that many companies use Internet-connected heating, ventilation, and air conditioning (HVAC) systems without adequate security, giving hackers a potential gateway to key corporate systems.

Boatner Blankenstein, senior director of solutions engineering at Bomgar, a company that provides tools for securing remote access, said the Target breach shows why companies need to implement measures for controlling what third-parties can do on their networks.

Large enterprises often grant remote access rights to software, hardware, and numerous other vendors and external third parties. But few have measures in place for ensuring that the access is properly authenticated and secured.

While many companies might routinely log remote access sessions, few have capabilities to audit the access from a security standpoint, he said.
