Abstract
Techniques for destination domain extraction for secure protocols are disclosed. In some embodiments, destination domain extraction for secure protocols includes monitoring network communications between a client and a remote server; determining if the client sends a request to create a secure connection with the remote server (e.g., in which the network communications are initiating a setup for a secure protocol-based connection); and extracting a destination domain from the request to create the secure connection with the remote server. In some embodiments, the secure protocol is a secure sockets layer (SSL) protocol or transport layer security (TLS) protocol, and the destination domain is extracted from the server name indication (SNI) of a client hello message sent from the client to the remote server. In some embodiments, destination domain extraction for secure protocols further includes applying a policy (e.g., a security policy) based on the destination domain to filter traffic using a security device.
