Halas [83] revealed the need to identify encryption algorithms that are suitable for PLC devices. Zonouz, Rrushi, and McLaughlin [74] suggested the application of encyrption algorithms in PLC networks to reduce the possibility of reverse analysis on communication protocols.…”

One key role in industrial control systems (ICSs) is known as Programmable Logic Controller (PLC). However, with the development of the Internet of Things (IoT), PLCs have become exposed to an increasing number of attacks, which may cause malfunctions of the whole ICS. Thus, it is necessary to identify potential attacks on PLCs and propose effective solutions to mitigate them. Unfortunately, to date, there have not been significant efforts made to provide a detailed overview of existing works on PLC security. With such a concern in mind, in this paper, we focus on summarising PLC security from different components running at different layers of a PLC architecture. We first review the framework of PLCs; then, we discuss several models when considering PLC security. After that, we provide an overview of existing attacks on PLCs and general solutions to those issues from different perspectives. Lastly, we conclude this paper with an overview of future research areas in PLC security.

“…Yau et al [16] proposed using semisupervised machine learning to detect anomalous PLC behavior based on captured PLC memory address values. Halas et al [17] proposed using encryption algorithms to encrypt data on PLCs to achieve the goal of data integrity. This approach has compatibility issues with existing protocols in use.…”

Supervisory control and data acquisition systems (SCADAs) play an important role in supervising and controlling industrial production with the help of programmable logic controllers (PLCs) in industrial control systems (ICSs). A PLC receives the control information or program from a SCADA to control the production equipment and feeds the production data back to the SCADA. Once a SCADA is controlled by an attacker, it may threaten the safety of industrial production. The lack of security protection, such as identity authentication and encryption for industrial control protocols, increases the potential security risks. In this paper, we propose a PLC protection system combined with a monitor between a SCADA and a PLC and a physically separated monitoring station. By using the PLC protection system, identity verification and command verification are separated, and both the identity of the operator and the corresponding commands are recorded. Experiments show that even if the SCADA is controlled by an attacker, our system could still protect the PLC in the field and record the identity of the key command operator, which facilitates the tracing and forensics of malicious activities.

Abstract-This article presents the software Asterisk PBX solution design in enterprise PLC network (Power Line Communication). The description of the installation and configuration of software Asterisk PBX is involved in the design. The secure interconnection of two enterprise PLC network is implemented via the telecommunication tunnel with security grant using the Cisco routers. The connection between two Asterisk PBXs is designed in context of the establishment of the tunnel. The subject of the article is also cross/connection of exchanges Asterisk PBX and hardware PBX -IP Panasonic PBX K-NS500. Keywords-Asterisk PBX solution, PLC technology, IP Panasonic KX-NS500I. INTRODUCTION VoIP (Voice over IP) technology has a number of advantages unlike public telecommunication network PSTN (Public Switched Telecommunication Network). The biggest advantage is cost savings when calling. Instead of paying telephone lines and circuits, customers pay only for the data connection. In addition, IP packets can be routed to any location with an Internet connection. As a part of the cost savings, employees can call in the enterprise network for free. Another advantage is the use of an existing network infrastructure, so it is no longer necessary to use the traditional telephone cables for interconnection of PBX. It is also possible configuration of the PBX from any location via the command line CLI or web interface. When communicating via VoIP because of additional cost savings for the company. VoIP technology is characterized by interoperability with older public telecommunication system PSTN. [1] In addition, voice in VoIP technology does not require high bandwidth (several kbit/s) and therefore is in the actual calls in corporate network, constructed based on PLC (Power Line Communication) technology which is described in [2][3][4][5][6][7][8][9][10], does not expect a significant reduction Manuscript received August 19, 2016, revised December 29, 2016 in quality of service. Therefore, PLC technology with lowcost software PBX Asterisk is suitable for the creation of a telecommunication platform for small and medium enterprise networks. II. SOFTVARE PBX ASTERISKPBX Asterisk is freely available software solution based on Linux. In addition to IP telephony, this PBX allows to use digital ISDN (Integrated Services Digital Network) and analog phones that are still in use in many companies. Asterisk also supports connectivity to the PSTN and other VoIP networks. Nowadays, the software PBX Asterisk has become a big competitor for traditional hardware PBX. One of the Asterisk advantages is the low cost for constructing PBX, whereas the PBX can be run on a personal computer or server. Another advantage is quick and easy installation and management over web interface control panel. Asterisk supports multiple protocols such as IAX, SIP, H.323 and MGCP. Asterisk solution is designed mainly for schools, hotels, small and medium-sized companies, where it's possible to call the flaps completely free. Asterisk provides a large number of serv...
