This paper proposes a method to detect signaling storms in IIoT networks by monitoring control plane messages within the Open RAN architecture, aiming to identify malicious activity early.

Contribution

It introduces a novel approach leveraging Open RAN architecture for early detection of signaling storms in IIoT networks.

Findings

Effective early detection of signaling storms demonstrated

Open RAN-based monitoring improves security response times

Potential for integration into existing IIoT security frameworks

Abstract

The Industrial Internet of Things devices due to their low cost and complexity are exposed to being hacked and utilized to attack the network infrastructure causing a so-called Signaling Storm. In this paper, we propose to utilize the Open Radio Access Network (O-RAN) architecture, to monitor the control plane messages in order to detect the activity of adversaries at its early stage.
