The idea behind the Internet of Things (IoT) is that everyday objects can connect to each other and exchange data via the Internet. Even the smallest components, such as sensors for measuring temperature, angle of inclination or acceleration can send information or accept commands via the network. Current and future systems are based on the Internet protocol and will probably soon include ipv6 support. They transmit data in an open and well-known format. Depending on the application, data will most likely be transmitted via public networks. This means that data is in principle open to everyone who is connected to the network. Subject to the type of data the consequences range from unpleasant to catastrophic, which is why confidentiality must be protected and safeguarded. There are many ways of achieving this, especially through encryption.
High profile data breaches at companies like Mossack Fonseca, Target, Home Depot and Wendy’s along with Government controversies like Edward Snowden and the FBI’s legal suit against Apple after the San Bernadino shootings have severely dented public confidence in the ability of business and government to keep personal data safe and secure.
Anybody who uses the Internet uses, creates and leaves data behind. While in the past site visits were recorded in the depths of server log files rarely to surface again, these and related data are now the currency of the 21st century. Services are exchanged for data, this is the business model shared by Google, Amazon and many others. But people are becoming more aware that the uninhibited acquisition of their personal data may have negative consequences and no longer trust that their data is protected on the Internet.
Architects and city planners first began promoting the concept of Smart Buildings, or Building Automation Systems (BAS), around ten years ago. Smart buildings were meant to deliver untold benefits from energy efficiencies and greener lifestyles to cost savings and improved living standards for all. Early examples of IP-connected appliances, however, were not built to cope with the demands of an evolving threat landscape.
