The Internet of Things takes information security into the physical world. The barrier between physical and cybersecurity was created before we had all of our physical security and access systems using cyber technologies. We must take a holistic approach to defending our businesses and individual privacy, Hackers and cyber criminals do take a holistic approach and look for the weakest link... they do not make a distinction if your HVAC is being managed by the physical or cybersecurity team.
The high wall between physical and cyber-security was a recurring theme athis year's Security and Counter Terror Expo at London's Olympia centre provided delegates from all over the security industry with one dedicated stream of talks on cyber security and three others in which the topic figured heavily. There was one particular theme which figured heavily at the expo: the high wall around cybersecurity.
