Development of a cognitive model for analysis of the impact of threats on the security level of a computer network

Development of a cognitive model for analysis of the impact of threats on the security level of a computer network

It is impossible to imagine modern life without the use of computer networks, which offer many opportunities for their users. However, computer networks and their resources are constantly at risk of being infected by malware or from various types of network attacks. Therefore, for the proper functio...

The analysis of these indicators revealed the most dangerous threats to network security such as: malware, physical impact on the network by the attacker, unintentional actions and errors of network users. Increasing the impact of these concepts on the network, various scenarios have been simulated, resulting in a relative change in the security level of the network. It is revealed that with increased influence of the concept of «unintentional actions, mistakes of network users» the security will be reduced the most, and with the increase of the concept of «physical influence on the network by the attacker» the fault tolerance of network operation will worsen as much as possible. The results of this study will contribute to the implementation of the necessary mechanisms to prevent, protect and control access at the appropriate levels of network infrastructure. Tabl.: 2.

Сформовано матрицю взаємовпливів концептів нечіткої когнітивної карти та розраховано основні системні показники, такі як: консонанс, дисонанс і вплив концептів на систему. Аналіз даних показників дозволив виявити найбільш небезпечні загрози мережевій безпеці, що, у свою чергу, надає можливість вчасно провести відповідні заходи для послаблення ступеню негативних наслідків або ж запобігти їм.
