In October 2016 some of most heavily trafficked web site in US and Europe (e.g. Twitter, the Guardian, Netflix, Reddit and CNN) had more than one problem to guarantee the continuity of their online services. This because they experienced the worst DDoS (Distributed Denial of Service) attack in their history. In specific, a network of computers infected, with special malware known as a “botnet”, were coordinated into attacking a server with traffic until it collapses under the strain.
This situation was made possible by two main factors:
- DNS infrastructure vulnerability;
- Many cheap and not secured IoT devices connected (in particular cameras and DVR players), which made the life easier for cybercriminals.
After that attack, backbone providers have increased their security level but nothing has been done for the security of IoT devices.
Considering the area with more developments and investment in IoT and also considering the consumers’ demand and expectation, there are four sectors with high risk of security:
- Healthcare. The 2017 will be a year with more investment in IoT (more devices and digital applications) because IoT represents a solution for many different healthcare problems (e.g. patients with blood pressure can be monitored from home and also other preventive and diagnostics are possible). The risk is that attacks could disrupt the service and those could also steal personal IDs and data.
- Financial. This sector will face difficult time due to different situations. From one side, they have the challenge of Bitcoins and Artificial Intelligence and, on the other side, consumers’ devices and Apps could represent a threat.
- Retails. For 2017, the B2C revenue generated by apps and IoT (see recent Amazon developments) have a positive forecast but this will generate additional challenges to protect this business and sensitive consumer’s data.
- Communication and Media. Companies operating in this sector have the double necessity: strengthen their service security and still guarantee an easy access across multiple channels.
