Abstract

Problematika ovog rada bazira se na razvoju efikasnog sustava za zaštitu i nadzor mreža. U sklopu rada koristi se mini računalo Raspberry Pi kako bi se stvorio posrednik unutar mreže koji, pomoću programskih alata za nadzor i analizu mrežnog prometa, kontrolira tok podataka prema uređajima u mreži. U slučaju detekcije malicioznog prometa sustav može reagirati odbacivanjem paketa napadača i generiranjem informacija o samom napadu. Predloženi sustav ima više razina zaštite od kojih je svaka zamišljena za sustav određene složenosti. Kao temelj za testiranje sustava koristila se kućna mreža i računalni uređaji koji su spojeni na nju. Kućna mreža predstavlja sustav s najnižom razinom zaštite, dok su više razine zamišljene za manja poduzeća.

Abstract (english)

The core problem discussed in this thesis is the development of an effective network surveillance and security system. In the thesis, we use a mini-computer device Raspberry Pi to create a proxy inside a network that, with the assistance of tools for analysis and surveillance of network traffic, controls the data flow toward the devices inside the network. If malicious traffic is detected the system can reject data packages that come from the attacker and generate information about the attack. The suggested system has multiple layers of security with each developed for a system of different complexity. The basis for testing was a home network with several connected computers. It represents the low-level security system, while higher levels are intended for smaller companies
