Opis:: This article addresses some functional safety assessment procedures with cybersecurity aspects in critical industrial installations with regard to the functional safety requirements specified in standards IEC 61508 and IEC 61511. The functional safety management includes hazard identification, risk analysis and assessment, specification of overall safety requirements and definition of safety functions. Based on the risk assessment results, the safety integrity level (SIL) is determined for consecutive safety functions. These functions are implemented within the industrial control system (ICS) and/or the distributed control system (DCS) that consists of the basic process control system (BPCS) and/or the safety instrumented system (SIS). The determination of the required SIL related to the required risk mitigation is based on the semi-quantitative evaluation method. Verification of the SIL for the considered architectures o fthe BPCS and/or the SIS is supported by probabilistic models with appropriate data and model parameters including cybersecurity related aspects. The proposed approach is illustrated on the example of critical industrial installations.

Opis:: The aim of this article is to identify problems of the risk assessment of the electric / electronic / programmable electronic (E/E/PE) systems concentrating on the functional safety and security aspects. These aspects should be considered in an integrated way in the system life cycle. The role of functional safety solutions is effective reducing the risk from unacceptable level. The risk is defined as a combination of the probability of occurrence of harm and the severity of that harm. Security is concerned with the protection of assets including the E/E/PE systems or safety instrumented systems (SISs) from potential threats including cyber attacks. This article deals with current challenges and methodological issues of integrating the functional safety and security aspects of the programmable systems’ operation for the control and protection of hazardous industrial systems.

Opis:: W niniejszym artykule przedstawiona została problematyka związana z analizą bezpieczeństwa funkcjonalnego rozproszonych systemów sterowania i automatyki zabezpieczeniowej z uwzględnieniem zagadnień ochrony informacji. Powinny być one rozpatrywane w sposób zintegrowany w zależności od rodzaju komunikacji stosowanej do transmisji danych. W tym celu zaproponowano podział analizowanych systemów na trzy kategorie. Zaproponowane podejście zilustrowano na przykładzie rozproszonego systemu monitoringu i sterowania, który może korzystać z różnych kanałów przesyłu informacji.
The aim of this paper is to present some issues of the functional safety analysis of the distributed control, monitoring and protection systems including information security aspects. These aspects should be considered in an integrated way depending on the types of communication channels used. The classification of analyzed systems into three categories is proposed. The conventional functional safety assessment based on IEC 61508 and integrated with some information security aspects, based on ISO/IEC 15408, are presented. Proposed approach is illustrated by an example of distributed, monitoring, control and protection system using different communication channels.

Opis:: A security level of distributed control and protection system may have a significant impact on the results of functional safety analysis. However, the issue of integrating the safety and security aspects is difficult and usually is neglected during the functional safety analysis. This article presents a method of functional safety analysis which takes into consideration a concept of integrating these two aspects. It is based on proposed classification of communication channels used in the computer system / network and the scope of such system distribution. The functional safety analysis is to be performed at every stage of system lifecycle, but one of the most important parts is defining required safety functions and determining the safety integrity level for them. The integration concept might be taken into account at this stage. The basis of a method proposed is the assumption that the security level is considered as a risk parameter in graphs of functional safety analyses.
