Virtual Private Network (VPN) is a network technology that has been widely used in Internet communications. This paper conducts an in-depth study of the definition of VPN, the importance of Internet communication, and its practice in application fields such as privacy protection, remote office, geographical location restrictions, and public Wi-Fi security. We also provide an in-depth analysis of VPN security, including a comparison of different encryption protocols, data logging and privacy, potential vulnerabilities and attacks, and the importance of vendor selection. Through real case studies, we explore the security practices of reputable VPN providers and past VPN data breaches to provide users with insights on how to choose a trustworthy VPN provider and manage potential risks. Finally, we summarize the main findings and observations of this paper and propose future research directions, including future trends in VPN technology and further research recommendations. This dissertation all about giving users a clearer picture of how VPN tech works, and ways to boost your internet privacy and security.
