Abstract

See full text

Techniques for detecting encrypted tunneling traffic are disclosed. In some embodiments, detecting encrypted tunneling traffic includes monitoring encrypted network communications between a client and a remote server, in which the encrypted network communications are encrypted using a first protocol (e.g., Secure Shell (SSH) protocol or another protocol for encrypted network communications); and determining if the client sends a request to create a tunnel using the first protocol with the remote server. In some embodiments, detecting encrypted tunneling traffic further includes performing an action in response to determining that the client sent a request to create a tunnel using the first protocol with the remote server.
