Abstract

A method of operating a network message interceptor for enforcing an authentication policy for communication over a network between first and second network endpoints, the interceptor being in communication with the network and external to the first and second endpoints, the network including transport layer security, the method comprising the steps of: intercepting a handshake message transmitted over the network between the first and second endpoints; extracting a certificate for an authenticating one of the endpoints from the handshake message; determining a validity status of the certificate for confirming an identity of the authenticating endpoint; and preventing communication between the first and second endpoints based on a negatively determined validity status of the certificate.
