20.500.12556/DKUM-95072 Analiza uporabe vpn za podporo strankam Analysis of vpn for customer support V diplomskem delu smo se osredotočili na raziskovanje uporabe virtualnih zasebnih omrežij (VPN) kot orodja za zagotavljanje varne in učinkovite podpore strankam. Namen našega dela je bil predstaviti teoretične osnove VPN-tehnologije, raziskati varnostne vidike, ki spremljajo uporabo takšnih omrežij, ter praktično preveriti delovanje in učinkovitost VPN-povezav v okolju, ki posnema realne razmere v podjetjih. V teoretičnem delu smo najprej opredelili osnovne koncepte, kot so IP-naslovi, značilnosti varnosti računalniških omrežij in vrste varnostnih elementov, ki se uporabljajo za zaščito podatkov in komunikacij. Podrobno smo obravnavali tudi delovanje požarnega zidu in njegovo vlogo pri preprečevanju nepooblaščenih dostopov, oblikovanje varnostnih strategij, različne oblike tuneliranja, protokole (npr. PPTP, L2TP, IPsec, OpenVPN) ter VPN-topologije, kot sta oddaljeni dostop in povezava med mesti (site-to-site). Na podlagi analize smo ugotovili, da VPN predstavlja zanesljivo in varno rešitev za oddaljeno podporo strankam, še posebej v kombinaciji z ustrezno konfiguracijo, dobrimi varnostnimi praksami ter uporabo analitičnih orodij. In our thesis, we focused on exploring the use of Virtual Private Networks (VPNs) as a tool for providing secure and efficient customer support. The aim of our work was to present the theoretical foundations of VPN technology, examine the security aspects associated with its use, and practically evaluate the performance and effectiveness of VPN connections in an environment that simulates real business conditions. In the theoretical part, we first defined the basic concepts such as IP addresses, characteristics of computer network security, and types of security controls used to protect data and communications. We also thoroughly addressed the operation of firewalls and their role in preventing unauthorized access, the formation of security strategies, various forms of tunneling, protocols (e.g., PPTP, L2TP, IPsec, OpenVPN), and VPN topologies, such as remote access and site-to-site connections. Based on the analysis, we found that VPN represents a reliable and secure solution for remote customer support, especially when combined with proper configuration, good security practices, and the use of analytical tools.
