Abstract
Security is improved by adding a security heartbeat for and endpoint as a factor in a multi-factor authentication system. The security heartbeat may be used directly as an authentication factor, e.g., where the heartbeat provides a reliable and verifiable indication of identity, or the security heartbeat may be used as a gating input for some other verification method, e.g., where a text message with a temporary security code can only be transmitted to a user when the user's endpoint is providing a secure heartbeat.
