Most users of PCs are aware of the need for anti-virus software to combat threats from the internet. But surprisingly the same awareness doesn’t yet seem to extend to the smart grid and broader ‘Internet of Things’, with the many devices becoming interconnected offering many potential opportunities for hackers – whether malicious or simply up for the challenge – and the potential impacts extending to regions and even countries.
In a conversation (currently being prepared for publication) on the European DENSEK project, which is aimed to improve the cyber resilience of the region’s energy grids, it is apparent that the deployment of security is lagging the smart grid. The number of incidents has been growing with the same speed as smart grid technologies are being rolled out, but still many companies aren’t implementing preventive measures. Similarly with the Internet of Things, with a recent survey by HP finding that no less than 70% of common devices, such as TVs, home thermostats, door locks, etc., are vulnerable to attack with on average 25 vulnerabilities per device.

Fortunately when it comes to the grid, awareness is growing and many companies are implementing preventive measures, but still only a very few are considering preparedness for an actual attack. But many device manufacturers appear not be keeping up with even the most basic security issues such as password security, encryption and user access permissions.
Some smart grid project funding has recognized the importance of cyber security and demanded this be included in the project. This makes a good rule of thumb – that every smart grid - and Internet of Things - project should include a security component. And the best place to build it in is at the start, or what is termed ‘Security by design’ following the Ontario privacy commissioner’s associated ‘Privacy by design’.
