This defensive line is called “Attack-Tolerant” and it is based on the deception for the cyber-attacks. The attack-tolerant scheme is able to making the attacker believes that he has achieved the desired goal and as a result, the attacker stops the attack method improvement. Furthermore, there is an indication for the attacks will be included within the sensor reading which will be sent from the remote plant side to the local controller side. In order to implement the proposed mechanism, a specific algorithm will be designed along with Data Encryption Standard (DES), Message Digest (MD5), timestamp, and the mathematical model of the plant with acceptable limit of uncertainty. The simulation results of the proposed mechanism have been found to be satisfactory.","PeriodicalId":330133,"journal":{"name":"2015 World Congress on Industrial Control Systems Security (WCICSS)","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125273928","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this new quadratic of error performance function, an additional error of the reference control signal between the input of the plant and the inversed of the plant output is added to the conventional input error of the single neuron controller to update the neuron weights in its learning mechanism. To accomplish the new quadratic error function, an inverse neural network is necessary put into the structure of the control system, for providing the inversed plant output as the feedback of the control signal. By using this new quadratic error performance function, the single neuron PID controller system is evaluated and compare with that of the conventional single neuron PID system, in terms of the rise time, the settling time and the overshoot of the system. The simulation results show that the convergence speed of the new adaptive single neuron PID system is increased and the control performance is greatly improve, outperformed the classical single neuron adaptive PID controller, especially in its strong robustness and better self-adaptation.","PeriodicalId":330133,"journal":{"name":"2015 World Congress on Industrial Control Systems Security (WCICSS)","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114743649","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Most of the existing reported research in this area has been driven by practical objectives.

This paper is a contribution to this conception of security as a machine. It proposes an abstract apparatus to represent such a machine. The machine representation is based on a conceptual model with a flow system that acts as a system of interruptions or breaks.","PeriodicalId":330133,"journal":{"name":"2015 World Congress on Industrial Control Systems Security (WCICSS)","volume":"87 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114859912","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The traditional DBSy modelling partitions business processes and underlying IT infrastructure into logical domains of predefined confidentiality levels to enforce restrictions on sharing of information. While constrains on sharing of information are addressing requirements on confidentiality of the information, industrial control systems primarily require and rely on timely and correct information. Therefore, this short paper explores applicability of the DBSy modeling to SCADA industrial control system environments in which integrity and availability of information is important for correct operation of the system, protection of human lives and prevention of damages to environment. Examples are shown to illustrate that on confidentiality focused legacy style DBSy modeling can be extended to consider and address integrity and availability requirements of industrial control systems.","PeriodicalId":330133,"journal":{"name":"2015 World Congress on Industrial Control Systems Security (WCICSS)","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134209497","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To address these issues we apply Dempster-Shafer (DS) theory to correctly model the information so that it can be merged in a consistent way. Unfortunately, existing merging operators are not suitable for every situation. We adapt a context-dependent strategy from possibility theory where we determine the context for when to merge using Dempster's rule of combination (i.e. for low conflicting information) and then resort to Dubois and Prade's disjunctive rule to merge information which is highly conflicting. We demonstrate the suitability of our approach with a scenario of a smart grid SCADA system modelled using the Belief-Desire-Intention (BDI) multi-agent framework. In particular, we use the notion of epistemic states to model combined uncertain sensor information for better informed selection of predefined plans.","PeriodicalId":330133,"journal":{"name":"2015 World Congress on Industrial Control Systems Security (WCICSS)","volume":"73 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127325773","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
