Security in the Internet of Things

Security Requirements For The Internet Of Things

The data security and privacy are the most potential risks associated with the IoT. Privacy risks will be increased in the IoT as the complexity provides more vulnerability that is related to the service. In IoT, much information corresponds to personal information, such as budgets and date of birth, etc. This aspect requires a big data challenging, so the designer should pay more attention to the security and they should design security solutions in a big enough range for all parts in IoT.

The IoT should be implemented in a legitimate, politically, socially and acceptable way, where legal challenges, business challenges and technical challenges should be considered. Security must be addressed all along the IoT lifecycle from the initial design to the services running. The main research challenges in IoT scenario include the data confidentiality, privacy, and trust, as shown in Weber (2013), Gaur (2013), Di Pietro et al. (2014), Furnell (2007), Miorandi et al. (2012), and Roman et al. (2013).

Security Issues in IoT

The IoT environment is built on four layers which are physical, network, perception and application layers, as shown in Figure 2 (Miorandi, 2012; Sonar, 2011).
