Cyber-threat protection is today one of the most challenging research branches of Information Technology, while the exponentially-increasing number of tiny, connected devices able to push personal data to the Internet is doing nothing but exacerbating the battle between the involved parties.

Not to mention those millions of IoT devices already deployed without any hardware security support. In this context, it is crucial to develop tools able to detect such cyber-threats. In this paper, we present Passban, an intelligent Intrusion Detection System (IDS) able to protect the IoT devices that are directly connected to it. The peculiarity of the proposed solution is that it can be deployed directly on very cheap IoT gateways (e.g., single-board PCs currently costing few tens USD), hence taking full advantage of the Edge Computing paradigm to detect cyber-threats as close as possible to the corresponding data sources. We will demonstrate that Passban is able to detect various types of malicious traffic, including Port Scanning, HTTP and SSH Brute Force, and SYN Flood attacks with very low false positive rates and satisfactory accuracies.

Abstract

Cyber-threat protection is today one of the most challenging research branches of Information Technology, while the exponentially-increasing number of tiny, connected devices able to push personal data to the Internet is doing nothing but exacerbating the battle between the involved parties. Thus, this protection becomes crucial with a typical Internet of Things (IoT) setup, as it usually involves several IoT based data sources interacting with the physical world within various application domains, such as agriculture, health care, home automation, critical industrial processes, etc. Unfortunately, contemporary IoT devices often offer very limited security features, laying themselves open to always new and more sophisticated attacks and also inhibiting the expected global adoption of IoT technologies. Not to mention those millions of IoT devices already deployed without any hardware security support. In this context, it is crucial to develop tools able to detect such cyber-threats. In this paper, we present Passban, an intelligent Intrusion Detection System (IDS) able to protect the IoT devices that are directly connected to it. The peculiarity of the proposed solution is that it can be deployed directly on very cheap IoT gateways (e.g., single-board PCs currently costing few tens USD), hence taking full advantage of the Edge Computing paradigm to detect cyber-threats as close as possible to the corresponding data sources. We will demonstrate that Passban is able to detect various types of malicious traffic, including Port Scanning, HTTP and SSH Brute Force, and SYN Flood attacks with very low false positive rates and satisfactory accuracies.
