Abstract
In an embodiment, a computer-implemented method prevents use of a network protocol over an encrypted channel. In the method, a packet is received on an encrypted channel addressed to a network address. It is determined whether a network host at the network address is able to service a request formatted according to the network protocol over the encrypted channel. When the network host is determined to be able to resolve to a domain name over the encrypted channel, the network packet is blocked.
