Abstract

U današnjem svijetu bežične lokalne mreže postale su nezaobilazan dio svakodnevice. Pri tome najveću ulogu igraju upravo Wi-Fi mreže. Kroz pojavu pametnih telefona, tableta i ostalih uređaja koji imaju mogućnost bežičnog spajanja na Internet putem Wi-Fi-ja, još više je porasla popularnost te tehnologije. No kod Wi-Fi tehnologije i dalje postoje sigurnosni rizici, i to veći nego ikad prije zbog njene rasprostranjenosti. Većina ljudi nije svjesna načina na koji se Wi-Fi može iskoristiti kako bi se došlo do povjerljivih podataka. Danas je iznimno važno obratiti pažnju na to. U radu se provela anketa kojom se saznaje koliko su ljudi svjesni rizika koji su prisutni na Wi-Fi mrežama. Osim toga, korišten je i programski alat Vistumbler koji omogućava skeniranje Wi-Fi mreža u blizini te se skeniranjem Wi-Fi mreža u gradu Trogiru saznaje kakvo je stanje na terenu, odnosno kakvo je stanje Wi-Fi mreža u gradu što se tiče sigurnosnog aspekta.

Abstract (english)

In today's world, wireless local networks have become an indispensable part of everyday life. Wi-Fi networks play the biggest role in this. Through the appearance of smartphones, tablets and other devices that have the ability to wirelessly connect to the Internet via Wi-Fi, the popularity of this technology has grown even more. But there are still security risks with Wi-Fi technology, greater than ever before due to its prevalence. Most people are unaware of the ways in which Wi-Fi can be exploited to access confidential data. Today it is extremely important to pay attention to it. In the paper, a survey was conducted to find out how much people are aware of the risks lurking on Wi-Fi networks. In addition, the Vistumbler tool was also used, which enables scanning of Wi-Fi networks in the vicinity, and by scanning Wi-Fi networks in the city of Trogir, it is known what the situation is on the ground, that is, what is the state of Wi-Fi networks in the city as far as the security aspect is concerned.
