OpenVPN Definition: OpenVPN is an open-source VPN that builds TLS-secured tunnels over UDP or TCP port 443, using OpenSSL to traverse firewalls across major platforms.
OpenVPN is a widely used open-source VPN solution that creates secure point-to-point or site-to-site tunnels using the OpenSSL library for encryption and TLS for key exchange and authentication. It can operate over UDP for performance or over TCP, commonly on port 443, to blend with HTTPS traffic and traverse restrictive firewalls. OpenVPN supports certificate, pre-shared key, and username-password authentication, and runs across Windows, Linux, macOS, and mobile platforms.
OpenVPN is one of the topics you'll master in the Security+ Boot Camp.
