OpenVPN OpenVPN Server Securityhas long been known as a flexible and secure protocol for VPN tunneling. The server aspects of OpenVPN are less openly discussed. The different aspects of an OpenVPN server allow it to function as an important part of the total VPN security package while maintaining ease of use. Three of the major advantages of OpenVPN is that it supports secret Static Key and public SSL/TLS security, scalability to mass users, and UDP/TCP tunneling. This is the basis for its superior server security and performance.

OpenVPN Server Capability

The Fast OpenVPN Server Processingintroduction of OpenVPN 2.0 brought in the “server” mode which carries out multi-client server capability. This allows the server to respond to network client requests more efficiently to return better and faster results. Multiple servers can also be networked together to handle increased processing load as the number of clients grows. This in turn allows more users to share access and improves scalability since connections are made as needed. OpenVPN is server platform independent, allowing greater flexibility in server management.

OpenVPN Server Security

Secure OpenVPN sever administration is provided by SecureShell tunneling. The encrypted tunnel created by the SSH protocol connection reroutes traffic to the remote fileserver through the encrypted channel which provides security. Added server communications security is provided by key-based authentication. OpenVPN relies heavily on SSL crypto infrastructure, ensuring that data encryption and transfer through the server is properly executed. OpenVPN runs best over UDP, a very low overhead data communications protocol designed to transmit data at very high speeds. TCP capability is also provided, and is not as fast but gives higher data delivery reliability for larger amounts of data. OpenVPN also doesn’t require kernel modules, which eliminates the need to patch in drivers when upgrading, lessening the load. The lighter server load ensures faster data transfer, further minimizing the risk of data OpenVPN Server Secure Shell Tunnelingleaks.

The “bind” procedure for the local host or IP address allows the servers to select what network interfaces they will receive UDP packets and TCP connection requests from. This limits the communication allowed to and from the server. Client options to adjust remote host settings through the connection profile further limit communication permissions. This is used by the OpenVPN client also to allow server connections in a specific order to control access for better server performance. This means better speeds and data processing for integrity. The authentication testing still functions in UDP mode if the bind is unspecified, on all potentials peers and IPs whether trusted or not. In TCP mode, remote options filter connections and reject those that do not match the host. When resolving to multiple IPs, one is selected for load-balancing and failover capability.

OpenVPN is the most secure, most reliable, and most flexible option available. OpenVPN is also the fastest and easiest to use. Choosing an OpenVPN service provider is the best option to take full advantage of maximum data security and integrity while assured of anonymity on the web, for any internet-enabled application. ExpressVPN OpenVPN ServerExpressVPN is one provider that offers OpenVPN by default to give users the best protection. OpenVPN is available from ExpressVPN for most desktop and Android users. ExpressVPN additionally secures users’ personal information, as staunch advocates of privacy. They maintain and upgrade fast and secure servers all over the world to continually deliver better connection options to users.
