Abstract [en]

Industrial systems have traditionally been kept isolated from external networks. However, business benefits are pushing for a convergence between the industrial systems and new information technology environments such as cloud computing, as well as higher level of connectivity between different systems. This makes cybersecurity a growing concern for industrial systems. In strengthening security, access control is a fundamental mechanisms for providing security in these systems. However, access control is relatively immature in traditional industrial systems, as compared to modern IT systems, and organizations’ adherence to an established cybersecurity standard or guideline can be a deciding factor for choices of access control techniques used. This paper presents the results of a questionnaire study on the usage of access control within industrial system that are being developed, serviced or operated by Swedish organizations, contrasted to their usage of cybersecurity standards and guidelines. To be precise, the article focuses on two fundamental requirements of cybersecurity: identification and authentication control, and presents related findings based on a survey of the Swedish industry.

Abstract [en]

Industrial automation and control systems (IACS) are taking care of our most important infrastructures, providing electricity and clean water, producing medicine and food, along with many other services and products we take for granted. The continuous, safe, and secure operation of such systems are obviously of great importance. Future iterations of IACS will look quite different from the ones we use today. Modular and flexible systems are emerging, powered by technical advances in areas such as artificial intelligence, cloud computing, and motivated by fluctuating market demands and faster innovation cycles. Design strategies for dynamic manufacturing are increasingly being adopted. These advances have a fundamental impact on industrial systems at component as well as architectural level. 

As a consequence of the changing operational requirements, the methods used for protection of industrial systems must be revisited and strengthened. This for example includes access control, which is one of the fundamental cyber­security mechanisms that is hugely affected by current developments within IACS. The methods currently used are static and coarse-grained and therefore not well suited for dynamic and flexible industrial systems. A transition in security model is required, from implicit trust towards zero-trust, supporting dynamic and fine-grained access control. 

This PhD thesis discusses access control for IACS in the age of Industry 4.0, focusing on dynamic and flexible manufacturing systems. The solutions pre­sented are applicable at machine-to-machine as well as human-to-machine in­teractions, using a zero-trust strategy. An investigation of the current state of practice for industrial access control is provided as a starting point for the work. Dynamic systems require equally dynamic access control policies, why several approaches on how dynamic access control can be achieved in indus­trial systems are developed and evaluated, covering strategies for policy for­mulations as well as mechanisms for authorization enforcement. 

Abstract [sv]

Vi tar för givet att det alltid ska finnas el, rent dricksvatten, mat och läkemedel. Många av våra grundläggande behov tillgodoses tack vare produkter som är beroende av industriella styrsystem. Att skyddas dessa system ifrån störningar är följaktligen ytterst viktigt. 

Vi är mitt i ett teknikskifte som brukar kallas "Industri 4.0" och som innebär att framtidens industriella system kommer skilja sig avsevärt ifrån dagens. Förän­dringen drivs bland annat av nya krav och förväntningar, exempelvis på ko­rtare tid mellan ide och produktion, möjlighet att anpassa produktionen till snabba marknadsförändringar och tillverkning av individuellt anpassade pro­dukter. Flexibla och skalbara lösningar krävs för att kunna uppfylla dessa krav, till skillnad från dagens system som i allmänhet är utvecklade för massproduk­tion av en specifik produkt. 

Detta påverkar såväl hur produktionssystemen konstrueras som designen av varje ingående komponent. En konsekvens är att metoderna som används för att skydda dagens system måste anpassas och stärkas för att möta framtidens utmaningar. En grundläggande sådan säkerhetsfunktion är behörighetshanter­ing. Nuvarande behörighetshantering är inte tillräckligt flexibel och därmed dåligt anpassad till morgondagens dynamiska system. 

I denna doktorsavhandling undersöks behörighetshantering för framtidens industriella system, med fokus på de dynamiska produktionssystem som behövs för att uppfylla kraven kopplade till Industri 4.0. Med utgångspunkt från en enkätundersökning analyseras dagsläget. Förslag på flera olika tillvägagångssätt för dynamisk behörighetshantering presenteras och utvärderas, såväl med avseende på hur sådana regler kan formuleras som på hur de ska kunna upprätthållas.
