On the downside, the great benefit carried by the IoT paradigm in our life brings simultaneously severe security issues, since the information exchanged among the objects frequently remains unprotected from malicious attackers. The paper at hand proposes COSMOS (Collaborative, Seamless and Adaptive Sentinel for the Internet of Things), a novel sentinel to protect smart environments from cyber threats. Our sentinel shields the IoT devices using multiple defensive rings, resulting in a more accurate and robust protection. 


Additionally, we discuss the current deployment of the sentinel on a commodity device (i.e., Raspberry Pi). Exhaustive experiments are conducted on the sentinel, demonstrating that it performs meticulously even in heavily stressing conditions. Each defensive layer is tested, reaching a remarkable performance, thus proving the applicability of COSMOS in a distributed and dynamic scenario such as IoT. With the aim of easing the enjoyment of the proposed sentinel, we further developed a friendly and ease-to-use COSMOS App, so that end-users can manage sentinel(s) directly using their own devices (e.g., smartphone).


The main contributions of this paper are summarized as follows:


  • The proposal of COSMOS (see Figure 1) based on a defense-in-depth approach oriented to perform the main security functions for asset protection (identify, protect, detect, react and recover) within an IoT ecosystem.
  • The design of a mechanism for sharing threat intelligence between IoT Sentinels, which is critical to guarantee collaboration, reduce incidents’ response time and prevent attacks.
  • The conception of an adaptive mechanism that allows for updating defense capabilities in IoT Sentinels, making them resilient to an evolutionary threat environment.
  • The development and evaluation of COSMOS as a full-fledged security framework aiming to be as much seamless as possible to users, automatic, portable, easy to deploy and manageable in a pragmatic way through a mobile application.
