OpenVPN security mechanisms

This section provides an introduction to the security mechanisms and modes of operation for OpenVPN on the vRouter.

  • Preshared secret
  • TLS

The security requirements for a virtual private network include authentication, confidentiality, and integrity. OpenVPN offers a choice of two different security mechanisms: preshared secret and Transport Layer Security (TLS).

Note: Secure Sockets Layer (SSL) is the predecessor of TLS, and most current references to SSL are, in fact, references to TLS. Therefore, these terms are used interchangeably in this document.
