Context Aware Security for Smart Homes

Context Aware Security for Smart Homes using Cyber Physical Data Analysis

The rapidly growing rate of Internet of Things (IoT) requires a deep look into the challenges of security and privacy. This rapid growth is changing our contemporary world, which is now connected in new ways, and thus poses new challenges, as our communication technology has changed greatly, even within the last decade. Nowadays, technological devices routinely communicate with each other on behalf of humans, and although currently most of these devices are designed to perform particular tasks, in the near-future, after the Artificial Intelligence (AI) revolution, more and more of these devices will be making their decisions based on Machine Learning (ML). As we move further into this AI era, the world needs assurance that this fabric of interconnected things is not vulnerable to any traditional or cyber-physical security threat. The entire spectrum of IoT fabric includes; devices/things, connectivity, storage, and applications – all of which are potentially vulnerable. IoTs can be the ‘weakest link’ to breaking into a secure infrastructure. Therefore, in order to achieve a secure future with IoT, some security challenges will need to be addressed.

A key objective of this project is to develop an IoT sensor network that can be deployed across a household and be able to detect cyber-physical attacks by analysing anomalies of behavioural data independently. In this project, we aim to combine traditional Network Traffic Analysis (NTA) with novel physical, behavioural data analytics to better detect cyber attacks. Physical behavioural data will be collected using different types of sensors.
