Virtually every study exploring the benefits of Internet of Things includes some reservations on IT security. According to an analysis by Deutsche Telekom 90% of managers are concerned about security (Cyber Security Report 2015), 70% of respondents surveyed by VDE see IT security risks (2) and a Bitkom survey reported more than 50 percent of study participants (3) were concerned about privacy and security. These concerns are well founded.
The average company network has many more devices connecting to it than even just a few years ago. In addition to traditional workstations there are now smartphones and tablets alongside a wide variety of Internet-connected equipment from printers, access control systems and security cameras to digital signage, smart TVs, thermostats and even everyday appliances like coffee machines. In situations where digital signage shares the network with such a diverse range of devices and applications use of software-based site-to-site VPNs are often the best way to ensure security, signal continuity and optimize flexibility.
Tor (The Onion Router) is one of the most important tools for anonymity on the Internet. The Tor network, protocol and client, make it extremely complicated to trace user activity. However, Tor users are not completely invisible. Firstly, only the connection to the exit node – the last server before traffic leaves the Tor network – is encrypted. Whoever controls the exit node can see data traffic in plain text. Meanwhile attacks and statistical analysis methods are known which can allow an organization with access to large parts of global Internet traffic to de-anonymize users in some cases. Nevertheless, Tor can protect users against the curiosity of most unauthorized parties if it is configured correctly. And a better solution is currently not available – at least not for the average computer user.
Advances in connected car technology are set to radically alter the future of driving for everyone. Among the promised benefits is the ability for cars to ‘learn’ from each other, provide early warning of mechanical problems and remotely interact with other devices. They may also allow insurers to accurately build up a ‘risk profile’ for every driver, leading to reduced premiums for some. Connected cars may even allow car manufacturers to target customers individually with software updates to suit their individual tastes.
