20.500.12556/DKUM-38329 MODEL VAROVANJA INFORMACIJSKEGA SISTEMA SCADA SECURITY MODEL OF INFORMATION SYSTEM SCADA Povzetek Predmet diplomske naloge je model varovanja informacijskega sistema SCADA. Kot izhodišče smo izbrali preučitev razpoložljive literature za vpogled v trenutno stanje na področju informacijske varnosti in predstavili različne poglede. Nato smo obravnavali informatizacijo poslovnih procesov s poudarkom na vlogo sistemov za spremljanje in kontrolo procesov in njihovo ranljivost zaradi vse bolj višje stopnje integriranosti s poslovnimi aplikacijami temelječih na internetni tehnologiji. Na podlagi pridobljenega znanja o uveljavljenih teoretičnih konceptih s področja informacijske varnosti in že razvitih referenčnih modelih s področja varovanja informacijskih resursov, smo razvili in predstavili model varovanja sistema SCADA. Pri tem smo, kot podlago, za oblikovanje modela uporabili splošni referenčni model za področje informacijske varnosti, funkcijski model za proizvodne procese in logični model. Model zagotavlja hierarhična uveljavitev strategije varovanja obramba v globino, kar je glede na stopnjo tehnološkega razvoja sistemov informacijske tehnologije in organizacijskih varnostnih politik ter družbenih odnosov, optimalna rešitev. Abstract The purpose of this undergraduate thesis is the security model of information system SCADA. As a starting point, available literature was examined to determine the current state of information security as well as to present various perspectives and views on this topic. Next, a discussion on the informatization of business processes is presented with a focus on the role of systems to monitor and control processes and their vulnerability due to increasingly higher levels of integration with business applications that are based on Internet technology. On the basis of obtained knowledge on established theoretical concepts in the field of information security as well as currently developed reference models from the field of securing information resources, a security model of the SCADA system was developed. To develop the model, a general reference model for information security was used as a basis, a functional model for production processes and a logical model. The model assures a hierarchical enforcement of strategy to secure an defence in-depth that considering the level of technological development of information technology systems, organizational security policies as well as social relations is the optimum solution. informacijska varnost varnostna politika ranljivost razpoložljivost mehanizmi napadanja obramba v globino informatizacija poslovnih procesov proizvodni in kontrolni sistemi sistemi SCADA model varovanja sistema SCADA information security security policies vulnerability availability mechanisms of attack defence-in-depth informatization of business processes production and control systems SCADA systems security model of SCADA system true true false [M.
