In this model the operation of a computer system is considered as a sequence of failures and recoveries, which result from information security threats affecting the sys- tem. The model is described in detail: explicit analytical formulas for probabilities of computer system states at any time are derived, some extreme cases discussed, and the system’s long-run dynamics is ana- lyzed. The dependence of a secure state probability (i.e. a state with no threats) on the probabilities of threats is investigated separately. In particular, it is shown that this dependence takes on essentially different forms for odd and even times. For example, in case of one
