Whitelists based multiple filtering techniques in SCADA sensor networks

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. © 2014 dongho kang et al.
