VPN
A Virtual Private Network is a technology that creates a safe and encrypted connection over a less secure network such as the internet, allowing users to send and receive data across shared or public networks as if directly connected to a private network.
It allows users to send and receive data across shared or public networks as if their computing devices were directly connected to the private network.
VPNs are used for a variety of purposes in cybersecurity. They can be used to secure data transmissions, protect user privacy, bypass geographic restrictions, and allow remote workers to securely access a company's internal network.
VPNs work by routing your device's internet connection through the VPN's private server rather than your internet service provider (ISP). This means that when your data is transmitted to the internet, it comes from the VPN rather than your computer. The VPN acts as an intermediary, so your true IP address is hidden, and it appears as if you're connected from a different location.
VPNs use a variety of protocols to create these secure, encrypted tunnels. Common VPN protocols include Point-to-Point Tunneling Protocol (PPTP), Layer 2 Tunneling Protocol (L2TP), Internet Protocol Security (IPsec), Secure Socket Tunneling Protocol (SSTP), and OpenVPN.
