Abstract

Rad nas najprije upoznaje s pojmom kibernetičkih napada i važnosti sigurnosti. Odabran je specifičan način prikaza sustava koji je općenito i formalno opisan. Uveden je pojam napadača i matematički opis njegova modeliranja pomoću Markovljevih lanaca odlučivanja. Definirani su deterministički i prilagodljivi napadač, a potom je modeliran sustav s prilagodljivim napadačem. Sve pretpostavke ponašanja napadača i sustava su navedene, a odabrane su da što bolje opisuju stvarni svijet. Na kraju su opisani testni primjeri na kojima se vidi ponašanje sustava u različitim situacijama. Dan je i kratak osvrt na trenutno stanje i moguća poboljšanja

Abstract (english)

This work introduces us with cybersecurity attack concept and importance of security. Specific representation of system is chosen and given with general and formal description. The attacker term is introduced and presented mathematically with Markov Decision Process. Deterministic and adaptive attacker are defined and the system with adaptive attacker is modelled. Attacker behavior and system assumptions are adduced and chosen to describe system as realistic as possible. At the end, various situation test examples are given so we could watch addaptive behavior. There is brief review of current condition and possible improvement.
