New Security Development and Trends to Secure the SCADA Sensors Automated Transmission during Critical Sessions

Abstract

Modern technology enhancements have been used worldwide to fulfill the requirements of the industrial sector, especially in supervisory control and data acquisition (SCADA) systems as a part of industrial control systems (ICS). SCADA systems have gained popularity in industrial automations due to technology enhancements and connectivity with modern computer networks and/or protocols. The procurement of new technologies has made SCADA systems important and helpful to processing in oil lines, water treatment plants, and electricity generation and control stations. On the other hand, these systems have vulnerabilities like other traditional computer networks (or systems), especially when interconnected with open platforms. Many international organizations and researchers have proposed and deployed solutions for SCADA security enhancement, but most of these have been based on node-to-node security, without emphasizing critical sessions that are linked directly with industrial processing and automation. This study concerns SCADA security measures related to critical processing with specified sessions of automated polling, analyzing cryptography mechanisms and deploying the appropriate explicit inclusive security solution in a distributed network protocol version 3 (DNP3) stack, as part of a SCADA system. The bytes flow through the DNP3 stack with security OPEN ACCESSSymmetry 2015, 7 1946 computational bytes within specified critical intervals defined for polling. We took critical processing knowledge into account when designing a SCADA/DNP3 testbed and deploying a cryptography solution that did not affect communications.

A Cellular Access and Monitoring System for Industrial Information Model and Design

“…In literature [10][11][12][13], traditional security designs and developments were conducted for SCADA systems, but a development is still required that will be more significant in the terms of security enhancements, without various protocols dependencies, and minimal interrupting of normal SCADA/DNP3 traffic. To fulfill these requirements, a cryptography based security enhancement is made in data link layer of DNP3 protocol.…”

“…In researches [11,14], simulation based multimedia environments were designed to carry the SCADA communication in industrial environments such as, water pumping station, gas station, electrical station and other SCADA industries, but are limited to specific station, and plant . Meaning that, automation and processing are simulated between sensors and actuators, by mean of programmable logical controllers (PLCs) but fail to display the information that have been occurred in transmission.…”

Centralized Connectivity for Multiwireless Edge Computing and Cellular Platform: A Smart Vehicle Parking System

“…Thereby, the system is considered as a fully automated system and reachable to numerous smart devices, such as cellular devices, laptops, and others, using the Internet access. However, the system is not designed with the considerations of security, that is, Internet security as well as the security protection against the potential system's vulnerabilities [48,49]. So, the comprehensive security design will be a major contribution to this study aimed to draft in nearly future; nevertheless, here in the current stage, this study considers the inclusive smart setup procedure which is useful during the verification process to verify whether or not the vehicle that beings utilizing the parking service is authorized or not.…”

Cross-layer design for reducing delay and maximizing lifetime in industrial wireless sensor networks

“…And applying our method to different uncoded modulation systems, i.e., MQAM (M-ary quadrature amplitude modulation) and MPSK (M-ary phase shift keying), confirmed its effectiveness. 4 The system model and problem statement…”

“…The wireless sensor networks have been developed for a long time [21][22][23][24][25][26]; with the development of wireless portable devices and sensor technology, the application of wireless sensor network in the industrial field becomes the focus of attention [2,4]. Industrial wireless sensor networks (IWSNs) is emerging in this background; it does not require wiring to be deployed at any time and has simple requirements for complex industrial sites; the device is small and easy to deploy and has powerful functions that can be used to detect and monitor a variety of visible and invisible physical phenomena in close range and high precision; and the strong practicality makes it to have broad application prospects in various fields of industrial production [1,2,9,10], especially with the rise of cloud computing [27] and fog computing [28][29][30], to make its development face greater opportunities.…”
