Whitelists Based Multiple Filtering Techniques in SCADA Sensor Networks

Abstract EN

Internet of Things (IoT) consists of several tiny devices connected together to form a collaborative computing environment.

Recently IoT technologies begin to merge with supervisory control and data acquisition (SCADA) sensor networks to more efficiently gather and analyze real-time data from sensors in industrial environments.

But SCADA sensor networks are becoming more and more vulnerable to cyber-attacks due to increased connectivity.

To safely adopt IoT technologies in the SCADA environments, it is important to improve the security of SCADA sensor networks.

In this paper we propose a multiple filtering technique based on whitelists to detect illegitimate packets.

Our proposed system detects the traffic of network and application protocol attacks with a set of whitelists collected from normal traffic.
