About the Project

The process of designing IoT protocols and sensors and the lack of standards are the main reasons why the IoT is an easy target for botnets. Network Forensics is the branch of Digital Forensics, where the evidence is network-related and exist in the form of logs, packets and network flows. Popular methods of investigating botnets include Honeypot, Network flow analysis, Intrusion detection systems, Visualization of Network traffic, Deep Packet Analysis etc. Multiple deep learning solutions have been proposed for application in the field of Network Forensics in recent years. Niyaz et al. (2016) used stacked auto-encoders in their implementation of a DDoS detection system for software defined networks. The multiple auto-encoders were greedily trained layer-by-layer, with the output of one layer being the input of the next. Then the entire network was fine-tuned as a classifier. Reported accuracy for distinguishing between normal and attack traffic was 99.82%, outperforming other classification methods such as shallow NN, while individual types of DDoS attacks were identified with an accuracy of 95.65%. Lotfollahi et al. (2017) used a combination of a one-dimensional CNN and stacked auto-encoders for automatic feature extraction and classification of network traffic, achieving both application identification and traffic characterization in either encrypted or unencrypted traffic.
This project will explore the use of Recurrent Neural Network (RNN), Convolutional Neural Networks (CNN), Deep Auto Encoder (DAE), Deep Boltzman Machine (DBM) and Deep Belief Network (DBN), alongside some of the network forensics methods, whereby botnets in IoT can be effectively mitigated. For example, some ways of enhancing Honeypot implementations might include, making them more resilient against anti-forensics mechanisms, increasing the number of supported protocols thus increasing the range of mimicked IoT devices and handling the massive quantities of incoming traffic which could be generated by an IoT Botnet (N. Koroniotis et al., 2019)

This project is supervised by Dr Nauman Aslam.
