Prioritization of Cybersecurity Measures

Abstract

The considerable losses caused by the low levelof cyber security of companies, institutions and so on and the limited financial resources available imply the need to prioritize the implementation of measures to counter cyber attacks. For this purpose, the respective optimization problem is formulated as a Boolean mathematical programming one. At large dimensions, the use of known methods of solving the problem requires a large volume of calculations. That’s why, a simple rule for approximately solving the problem is obtained. By computer simulation, it is shown that the error of the solution when using this rule decreases considerably with the increase of the number of cybersecurity measures, more accurate – the more detailed such measures are. In order to reduce the error of solutions, three other simple algorithms are also proposed. The latter of these algorithms is more detailed and allows to reduce to a greater extent the solutions’ error.

A Differentiated Beneficiary Cybersecurity Approach

“…Adults (18+ years old) -ordinary cybersecurity. Knowing the categories of beneficiaries, they are also necessary to: a) identify and systemize the dangers, vulnerabilities and needs regarding the cybersecurity of beneficiaries (by categories); b) define the priorities and stage the measures and actions for cybersecuring the beneficiaries, taking into account the approach [30]; c) systemize the cybersecurity means to be used, taking into account the priorities (b); d) set up the models of cybersecuring the beneficiaries (by categories); e) define the set of criteria characterizing the degree of cybersecurity provided by models (d); f) explore and characterize the system of models (d); g) implement step by step the models (d) in practice, taking into account the results obtained according to items (e) and (f).…”
