VPN - Ferramenta de Segurança Computacional

Abstract

This article aims to analyze security in public access networks obtained through the use of VPN connections. Bibliographic reviews and practical vulnerability tests were conducted to observe the security and privacy of data during network access with a VPN, evaluating aspects such as IP address protection, geolocation, open ports, data traffic, DNS and WebRTC leaks. The results of these tests showed a low occurrence of vulnerabilities and protected data traffic, demonstrating that VPN connections significantly contribute to the protection of user data while browsing on public access networks, guaranteeing greater privacy, anonymity, and data security. However, disadvantages include increased latency, network overload, and instability.
