Research and Thesis Topics in Deep Learning-based Attack Detection for RPL Routing Protocol

A network of interconnected smart devices, machines, and related software devices is termed the Internet of Things (IoT). In modern society, IoT plays a crucial role and enables energy-efficient automation to improve the quality of life. A wide range of IoT applications is in industrial scenarios, smart homes, intelligent healthcare, and smart cities.

The importance of IoT applications is to secure the IoT networks from attacks. Cyber-attacks or network attacks in IoT significantly cause disruption and loss of information. Low Power Lossy Network Routing Protocol (RPL) is mainly affected by the attacks on IoT. RPL is an effective protocol that allows communication in a wireless network with low power consumption and limited resources. RPL is effectively used in different applications limited to healthcare, smart environments, transport, industry, and military applications.

RPL attacks are hard to defend against due to the improvised nature of IoT systems and the resource constraints of IoT devices. RPL attacks affect the IoT networks from both the outside and inside nodes. Continuous security and robustness against RPL attacks are needed to achieve the systems confidentiality, integrity, and availability of IoT networks. Some RPL attacks are sinkhole attacks, wormhole attacks, persistent attacks, distributed denial-of-service, clone ID, sybil attacks, and many more. The deep-learning-based method is a successful approach for detecting attacks in RPL and predicting IoT network abnormal and normal behavior.

Deep learning models handle complex prediction, classification, and detection tasks more accurately than machine learning models. Architectures of deep neural networks utilized for deep learning-based attack detection in RPL are multi-layer perceptron (MLP), generative adversarial networks(GAN), deep belief networks (DBN), and convolutional neural networks (CNN).

Significance of DL-based Attack Detection for RPL Routing Protocol

Complex Attack Patterns: Traditional rule-based and signature-based security mechanisms struggle to detect novel and sophisticated attack patterns. DL models recognize complex, non-linear patterns in data, making them well-suited for identifying known and previously unseen attacks on RPL.
Evolving Threat Landscape: The threat landscape in IoT is constantly evolving, with attackers devising new tactics and exploiting vulnerabilities. DL models can adapt to changing attack patterns through continuous learning, making them more robust against emerging threats.
Reduced False Positives: DL-based models can reduce false positive rates in attack detection, minimizing the chances of generating unnecessary alerts and allowing security teams to focus on genuine threats.
Adaptation to IoT Evolution: As IoT technologies evolve, DL-based attack detection can be updated and fine-tuned to address new challenges and requirements, ensuring the long-term security of IoT ecosystems.

Drawbacks of DL-based Attack Detection for RPL Routing Protocol

Data Intensive Training: Deep learning models for attack detection require large volumes of labeled data for training. Acquiring and annotating such data can be challenging and expensive, particularly for RPL attacks, which may not always be readily available.
